What are the most innovative uses of Aluminum Posted by: 1-LVDCPN - 12-17-2018, 07:22 AM - Forum: aluminium faq - No Replies In 2001, the aluminum industry continues to benefit from technical innovations made in alloy development, product-manufacturing technologies, and processing equipment over the last century. This paper examines the top ten alloy, product, and process developments that have shaped the industry抯 production methods and markets. The inter-relationships among the alloy development, process innovations, and markets are highlighted. Omitted are details about patent literature or the inception of many technologies; the major criterion for placement on the list was impact on the total industry. INTRODUCTION The aluminum industry has evolved over the past 100 years from the limited production of alloys and products to the high-volume manufacture of a wide variety of products. Today抯 U.S. aluminum production includes roughly 5.6 million tonnes of flat-rolled products, 1.7 million tonnes of extrusions and tube, and 2.4 million tonnes of ingot/castings.1 These products are used in a wide variety of markets, including building and construction, transportation, and packaging. Markets also exist for such products as electrical conductors (EC), forgings, rod, wire, bar, and powders and pastes, as shown in the 搊ther� category in Figure1. Following is an analysis of ten innovations that influenced aluminum production methods and markets. Although Alcoa was the source of much of the historical perspective, two factors may excuse this to some degree: Many of these developments took place before the birth of Alcoa抯 major competitors. While Alcoa抯 early technical history is well documented, little was found in the open literature on early European developments. DIRECT-CHILL CASTING Casting in the early days of aluminum production consisted of making 45 kg ingots in steel-tilt molds.2 As shown in Figure 2, the family of alloys that could be offered to aluminum customers was growing by the 1920s. Supplies were limited by difficulties with casting and ingot quality, however. The tilt molds suffered from macrosegregation, porosity, and a tendency toward severe shrinkage cracking when the alloy content increased. Alcoa fabricating plants coped with casting inefficiency, poor ingot quality, and size limitations. Recovery losses were realized as the tilt molds had to be 搒calped� substantially to remove undesirable surface segregation. William T. Ennor, of Alcoa抯 Massena operations, devised the idea of directly impinging water on the solidified shell of an ingot as it was cast. Using the direct chill (DC) process, it was possible to drop the ingot continuously and avoid the turbulence associated with pouring metal into the old tilt molds. Ennor抯 patent3 provided the basis for modern DC-casting technology, which was introduced into virtually all of Alcoa抯 plants during the 1930s. The plants built by Alcoa for the war effort incorporated this technology to make aluminum products for the aircraft industry. In 1951, just after Alcoa抯 Davenport works was completed, the largest aluminum ingot fabricated was approximately 3.1 tonnes.4 During the 1950s, DC ingots were available to make the large products needed by the aerospace, marine, and transportation industries. Size increases continued over the years梩oday抯 sheet ingots may reach 15.5 tonnes and extrusion billet are produced as large as 1.2 m in diameter. Figures 3a and 3b show typical cast sheet ingot and extrusion logs used in today抯 aluminum industry. In addition to allowing for larger ingots, DC casting helped improve product characteristics. Figure 4 shows the advancements in average mechanical properties and fatigue-endurance limit for alloys 2024 and 2017 as DC casting became the standard within the U.S. aluminum industry.5 On the process side, it became necessary to re-engineer the downstream paths for some products. Alloy 3003 tilt-mold ingots, which cooled extremely slowly after solidification, required only modest thermal treatments to produce fine-grained products. However, the more rapid solidification of DC ingots resulted in significantly more manganese in solution as well as problems with coarse grain size. W.A. Anderson and others solved those problems by applying high-temperature homogenization practices to the ingot. As the product-size capabilities increased with DC casting, so did the capability to develop new alloys, such as high-strength alloy 7075, introduced during World War II. In the 1950s, new markets for shipbuilding required large ingots of higher magnesium 5xxx alloys such as 5086 and 5083. Other high-magnesium alloys, 5082 and 5182, were developed in conjunction with horizontal DC casting in the 1960s to supply the growing can-sheet market. Today抯 complex, higher solute 2xxx and 7xxx alloys could certainly not be cast in the sizes needed for aerospace applications without high quality DC ingot. Neither could the coils of 3xxx or 5xxx alloy can sheet be produced in the economic sizes demanded by the beverage-can industry. HEAT-TREATABLE ALLOYS Much has been written about the accidental discovery of aluminum alloys� heat-treatable capability 6,7 by German researcher A. Wilm in 1908. During World War I, the Germans produced Duralumin for 80 airships梞ore than 726 tonnes in one year.8 Alcoa obtained the rights to Wilm抯 patent after World War I and began research that led to alloys such as 25S (2025), 14S (2014), and aluminum-magnesium-silicon alloy 51S (6051), which were easier to fabricate than Duralumin. Forged aluminum propellers were used on airplanes as early as 1922. By 1936, the major heat-treatable systems, aluminum-magnesium-silicon, aluminum-magnesium-copper, and aluminum-magnesium-zinc, had been mapped out by researchers.9 With its improved strength, aluminum played a key role in the development of higher-performance aircraft.10 The 2xxx (aluminum-copper) alloys quickly reached a plateau with the development of 24S (2024) in 1933, in which the aluminum-magnesium-copper phase diagram was exploited for maximum solubility. Because of their high strength, toughness, and fatigue resistance, modifications of 24S as well as the original alloys are still widely used today for aircraft applications. Alloy 75S (7075), developed during World War II, provided the high-strength capability not available with aluminum-magnesium-copper alloys. Modifications to the base alloy composition resulted in higher toughness (alloys 7175 and 7475) while the T7xx tempers alleviated stress corrosion and exfoliation problems inherent with the T6 temper. The composition of alloy 7050 was designed to reduce quench sensitivity in thick-section T7xx products. Additional development has extended the ability of aluminum alloys to reduce weight and increase aircraft performance. This development continues today, with the T77 tempers being utilized with special alloy compositions to attain levels of strength and corrosion performance not matched by previous materials.   How much aluminum is an aluminum can? Posted by: 1-LVDCPN - 12-17-2018, 07:18 AM - Forum: aluminium faq - No Replies The whole beverage container is fabricated from aluminum. Based on a North American standard 12 global. oz or 355ml can. Cans are being made lighter every year. An aluminium beverage can weighed 16.55g in 1992 and 15.5g in 1997. This amounts to nearly 6% reduction in the raw material being used. By 2005 the aluminium can weighed about 14.70g.   Why are cars not made of aluminium? Posted by: 1-LVDCPN - 12-17-2018, 07:17 AM - Forum: aluminium faq - No Replies Aluminum builds a better vehicle. Aluminum's use in autos and commercial vehicles is accelerating because it offers the fastest, safest, most environmentally friendly and cost-effective way to increase performance, boost fuel economy and reduce emissions while maintaining or improving safety and durability. Steel and aluminum is continually fluctuating based on global supply and demand, fuel costs and the price and availability of iron and bauxite ore; however steel is generally cheaper (per pound) than aluminum. Competitive materials, such as aluminium, are at a significant cost disadvantage over steel for all aspects of the car body structure manufacturing process. STEEL vs ALUMINIUM In raw material costs,Aluminium is 3 times more expensive than steel. In conversion cost,aluminium is 2 times more expensive than steel. In assembly,aluminium is 20 to 30 % more expensive than steel. In total,an aluminium structure is estimated at 60 to 80 % more expensive than a conventional steel design.   The alloy grades of traffic signs aluminum sheet Posted by: 1-LVDCPN - 12-17-2018, 07:05 AM - Forum: Knowledge & Technique - No Replies Aluminum alloy sheet is generally used for traffic signs, and is the addition of other elements of the aluminum sheet. Often used as a marker is a layer of painted aluminum, mostly blue, green and yellow color coated aluminum. Because the color coated aluminum sheet has good reflective effect and corrosion resistance, it has been widely used in the field of traffic signs to remind pedestrians and vehicles, but also can be used as road partition. In our daily lives, we will see that the signs aluminum sheet everywhere. So, the traffic signs are used in color coated aluminum sheet is mostly what models and specifications? haomei Aluminum details for you: Traffic signs aluminum sheet is coated with a layer of aluminum coated with the color of the aluminum sheet, aluminum processing industry, said the color coated aluminum plate or color coated aluminum roll, according to the specific needs of different colors painted. Color coated aluminum sheet can not only be used in the field of road signs, in the field of construction, decoration and packaging of electronic products have a wide range of applications. Aluminum alloy sheet used in the traffic signs is commonly used alloy 3003, 3004 and 5052 color coated aluminum coil, thickness is 0.25-2.5mm, and width and length can be customized according to customer specific needs. haomei aluminum is a professional aluminum sheet and color coated aluminummanufacturers.

Posted by: 1-LVDCPN - 12-14-2018, 09:16 AM - Forum: aluminium faq - No Replies Aluminum plate is a very large amount of metal, many users and dealers will have some in stock, be ready for use at any time. Aluminum plate is a more active nature of the metal, if it is not in the proper storage, there will be deformation, discoloration, corrosion and other unexpected circumstances, affecting the normal use. So, how is the aluminum plate stored properly?  how is the aluminum plate stored properly? 1, Environment requirements for aluminum storage: Aluminum plate should be stored in a constant temperature, dry humidity appropriate indoor environment, in order to ensure that the aluminum plate will not be due to water and oxidation discoloration. Many users have very high requirements for the aluminum surface brightness, if the aluminum surface is oxidized, it will lose the original luster, so be sure to pay attention. 2, the placement of aluminum plate, is often overlooked by everyone, in fact, this is also very important. In particular, some direct users, without wood case, put yhr aluminum plate on the ground, not knowing the humidity near the ground is much larger than the above space, resulting in the bottom of the aluminum will be affected by oxidation, and prone to be injured, scratches. And aluminum between the wooden care interval, more conducive to ventilation, so that aluminum is not easy to moisture. All the aluminum plates of haomei Aluminum are packed in high quality wooden care above the wooden material moisture through rigorous testing, both to ensure the safety of aluminum, but also facilitate the storage and use of customers. 3, the third point is for the user, because of the vast local area, the temperature difference between the obvious, users get aluminum plate, we must not rush to open the packaging, the first thing we should to do is to place aluminum plate in a well-ventilated place for 3 days, so that aluminum inside and outside temperature difference achieve balance, and then open the package to use. This can ensure that the aluminum plate will not be too much because of the temperature and water vapor, to ensure the absolute quality of aluminum qualifie     What certification does 5083 Marine aluminum have Posted by: 1-LVDCPN - 12-14-2018, 08:48 AM - Forum: aluminium faq - No Replies 5083 aluminum plate is one of the most common alloy products of Marine aluminum field. Planking of other products such as 5052, 5383, 8784, 5454, such as alloy, were also the representative of 5 series Marine aluminum products, among them, 5083 Marine planking alloy aluminum plate is the most widely used. Planking aluminum alloy compared with general aluminium alloy products, it will be more strict inspection, when in the market for the purpose of ship, also want to be approved by the relevant national certification authority. So just what certification standard does5083 Marine aluminum plates have? First of all, for the domestic market of planking, 5083 aluminum products should pass through by CCS China classification society certification. CCS, founded in 1956, has a new vessel inspection and international experience, for the domestic construction and inspection of shipping vessels provide a wide range of services Domestic aluminum plate to be ship raw material of aluminum plate, should be certified by CCS. Second, for international planking market, each country has different classification society certification.Bureau veritas certification such as BV, LR type classification, the RS Russian register of shipping, NK Japan classification society certification. 5083 represented by Marine aluminum sheet if you want to enter the international market, also must through the international quality approval. In addition, det norske veritas DNV approval certificate, the quality for planking international market, is said to be a general of foreign trade license. For det norske veritas certification means that the most authoritative international ship and strict quality approval, therefore can almost universal around the world. At present, the domestic several strength strong large manufacturers have passed the international recognition of 5083 Marine aluminum plate. High quality planking is the core elements of shipbuilding. Therefore when Marine aluminum plate of choose and buy should be from some of the large manufacturer to select the strong comprehensive strength, such as in 5083 Marine aluminum plate, can choose to have recognized by det norske veritas haomei aluminum, Chongqing southwest aluminum, etc.   Aluminum Plate Elongation Posted by: 1-LVDCPN - 12-13-2018, 09:15 AM - Forum: Knowledge & Technique - No Replies Aluminum plate, it is to point to made of pure aluminum or aluminum alloy materials through pressure processing (shear or sawing) cross section is rectangular, thickness of rectangular material, aluminum material. Aluminum plate advantages: Aluminum sheet is usually according to the following two points: A, according to the alloy composition is divided into: 1, high purity aluminum plate rolling (by the content above 99.9 high purity aluminum) 2, pure aluminum plate (ingredients made from pure aluminium rolling) 3, alloy aluminum plate (composed of aluminum alloy and auxiliary, usually with aluminum and copper, aluminum and manganese, aluminum and silicon, aluminum and magnesium, and other series) 4, composite aluminum plate or brazing plate (through a variety of means of material compound special use aluminum material) 5, package aluminum aluminum (aluminum cladding outside aluminium sheet used for special purposes) Second, according to the thickness is divided into: (mm) 1, the sheet (aluminum sheet) 0.15 to 2.0 2, regular plate (aluminum sheet) 2.0 to 6.0 3, medium plate, aluminum plate), 6.0 to 25.0 4, thick plate, aluminum plate) 25-200 five reinforcement pattern aluminum plate above 200 Aluminum plate elongation is introduced: Elongation (delta) : material after tensile failure, the percentage of the total elongation and the original gauge length. Engineering is often called a delta of 5% or more material plastic material, such as room temperature static load of low carbon steel, aluminum, copper, etc.; And the delta 5% or less of materials known as brittle materials, such as room temperature under the static load of cast iron, glass, ceramics, etc. Elongation of aluminum plate elongation related factors: aluminum and aluminum plate number, the thickness of the aluminum plate, aluminum plate contact state has obvious. 1, aluminum nameplate: conventional 1 XXX department, department of * * * 3, 5 XXX series high elongation, of course, is only relative to the 4 XXX and 7 XXX series of hard alloy series. 2, the thickness of the aluminium plate: the higher thickness, elongation relatively. 3, aluminum plate, aluminum plate state and elongation rate are the most direct contact, with 0 for full annealing state, elongation reached the highest, according to the state classification and so on, elongation decreases.   Comparison between Aluminum Strip and Copper Strip Posted by: 1-LVDCPN - 12-13-2018, 09:09 AM - Forum: Knowledge & Technique - No Replies Electronics is playing an ever-increasing role currently. Copper is not the only choice as the raw material in electronics. In comparison to aluminum copper is heavy and expensive. Aluminum strip to replace copper strip as a raw material in electronics is becoming an international trend. Aluminium strip is a high aluminum content product with aluminium content more than 99.6%-99.7%, and the electricity& thermal conductivity properties is also outstanding. The good electricity conductive metals top 7 are as follows: silver, copper, gold, aluminium, nickel, steel and alloys. As the copper price is much higher than aluminium, so the aluminium strip becomes the first choice for transformer strips. Features of aluminum strip: flat mill finished surface, cutting edge with no burr, thin and light, high strength, high thermal conductivity and electric conductivity, excellent silvery white luster. Aluminum strip typically used to wrap and shield multi-pair process control, cable, optical cable, PPR, printing plates, nameplate, heat exchanger, computer and instrumentation cables such as Coaxial CATV cables, LAN cables and HDMI cables. haomei aluminium . is a professional Aluminium Strip Suppliers and Aluminum Circles manufacturers,mainly supply Aluminum Circles, Aluminium discs, Aluminum Strip, Food Box Material Aluminum Foil, Aluminum Circles for Kitchenware etc. series of aluminum products, sincerely welcome everyone to visit.   Do you know the application of the aluminum foil strip in the transformer winding?

Posted by: aadaasdark8072 - 12-12-2018, 07:38 AM - Forum: aluminium faq - No Replies Simply, the numbers are different “temper” process on 6061 alloy. – This explains the different T temper processes…. Once a process is defined, the engineer or quality group should lock down the specific type of aluminum that is best for the application. Company quality groups can identify the material used from the prototype inspection sample warrant and material certification. Engineering can then update the print material designation for the production run. To understand some of the thinking, you need to understand the differences in the “T” temper designations. T6 Temper – “Solution Heat-Treated and Artificially Aged” To get to the -T6 temper, the 6061-O aluminum billet is heated to about 990˚ F, then quenched in water, then aged at about 350˚ F for around 8 hours. That changes the typical yield strength from 8 ksi to about 35 ksi (ksi is a unit of stress, equivalent to 1000 lbf/in2). Plate T6 is called T651 – “Solution Heat-Treated, Artificially Aged and Permanent Set” Quenching in water puts residual stresses in the aluminum, since there is a surface-to-center cooling gradient. The -T651 designation means the aluminum mill took that extrusion and gave it a 1% to 3% stretching, or permanent set, to get rid of some of those residual stresses. Now we can machine it and it shouldn’t distort as much. Common specifications are ASTM-B209, and AMS-QQ-A-250/11 for plate. Extruded T6 is called T6511 – “Solution Heat-Treated, Artificially Aged, Permanent Set and Straighten” The final digit in the -T6511 designation (and how I know it was an extrusion, since this only applies to extruded stock) means that the aluminum mill is allowed to straighten the extruded bars, like in a press, to get the material to meet the straightness tolerances. Common specifications are ASTM-B221, and AMS-QQ-A-200/8 for rounds. Cold Finished/Rolled T6 is also called T651 – “Solution Heat-Treated, Artificially Aged, Permanent Set” Cold Finished, or also called rolled material, is designated as -T651, notice the extra “one” designation is missing. This applies to plate and cold finished rounds. The extra “one” is missing because the process is similar to plate. This material is commonly known as “screw machine stock.” This material has better manufacturing tolerances as compared to extruded. For example, a 1.000” diameter round bar in “close tolerance extruded rod” has a diametrical tolerance of 0.005’’, the “cold finished” is much more consistent, with a tolerance of 0.002’’. Additionally, a comparison of mechanical properties is very similar – both having a 35 ksi yield strength, but extrusion stock is 38 ksi ultimate tensile strength and cold finished is slightly more, at 42 ksi. Common specifications for cold finished / rolled are ASTM-B211, and AMS-QQ-A-225/8 for rounds. Summary of Metallurgical Differences Chemically and physically, all of the tempers are basically the same, although the grain structure and additional stresses from straightening may be present (if straightened, and most bars are straightened) in the -T6511 First Previous Next Last
