What are the problems with casting aluminum parts at home from reclaimed aluminum? Posted by: mepehuxit - 05-08-2018, 06:19 AM - Forum: aluminium faq - Replies (1) As someone who came from the foundry industry and has done a variety of different castings methods both professionally and at home, I think you will have several issues.    First, it depends on where your salvage comes from, and what method you are using for melting. The easiest to get would be cans, and if you are using a gas/solid fuel furnace, your dross percentage is going to be VERY high. The second issue is chemistry. What kinds of parts are you making? Most salvaged aluminum isn't a specific alloy (jungle gyms, picnic tables, cans etc). If you are talking about art or some kind, no biggy, but automotive parts are a huge difference.    Third is quality. You have no way of knowing if these parts are defect free, and no form of quality testing (most people don't have these amenities at home anyway). If this part is going to be under stress of any kind, and you have a massive bubble located inside, you wont know it until it fails.  If you are just messing around, I would recommend sand casting. If you are doing small pieces, I would recommend investment casting, but either way, I would not recommend making your own auto parts until you can guarantee that your parts are consistent and defect free.   What is the molar mass of aluminum? Posted by: ircasodle - 05-08-2018, 06:14 AM - Forum: aluminium faq - No Replies You want the value? 26.98 or do you want to know what it is? It is the average mass of all atoms of Al in their normal isotope ratio, and it is the mass of 6.23 x 10^23 atoms on the scale where an atom of carbon-12 isotope is taken as 12.000000000. This is very very easy to find in google! If a number is not what you were hoping for, it may suffice to give a definition instead. The molar mass of Aluminum is the mass in grams that 6.02 x10^23 atoms (Avogadro’s Number) or one mole of Aluminum weighs. This mass comes directly from the periodic table as Aluminum’s atomic mass, which is roughly 27.   What is the symbol of aluminium? Posted by: ircasodle - 05-08-2018, 06:11 AM - Forum: aluminium faq - Replies (2) Symbol: Al Atomic Number (Z): 13 Atomic mass: 26.98159 amu Number of Protons/Electrons: 13 Number of Neutrons: 14 Period: 3 Block: p-block Electrons per shell: 2,8,3 When the pure metal is obtained it is soft but it becomes hard when alloyed. It is ductile in nature and can be beaten into very thin sheets. It's a good conductor of heat and electricity because of the 3+ charge, meaning there are 3 declocalised electrons moving freely between each aluminium atom, which helps them to quickly pass the energy applied to it. It's also a corrosive resistant metal.   Where does aluminum come from? Posted by: askaluadmin - 05-08-2018, 06:04 AM - Forum: aluminium faq - Replies (2) Aluminium or aluminum is a chemical element with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic and ductile metal in the boron group. By mass, aluminium makes up about 8% of the Earth's crust; it is the third most abundant element after oxygen and silicon and the most abundant metal in the crust, though it is less common in the mantle below. The chief ore of aluminium is bauxite. Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals. Aluminium is remarkable for its low density and its ability to resist corrosion through the phenomenon of passivation. Aluminium and its alloys are vital to the aerospace industry and important in transportation and building industries, such as building facades and window frames The oxides and sulfates are the most useful compounds of aluminium. Despite its prevalence in the environment, no known form of life uses aluminium salts metabolically, but aluminium is well tolerated by plants and animals.Because of these salts' abundance, the potential for a biological role for them is of continuing interest, and studies continue.   Aluminum Coil Measurements Posted by: aluhm - 05-04-2018, 08:34 AM - Forum: Knowledge & Technique - No Replies In addition to aluminium alloy grades and tempers, when selecting aluminum coil stock for sale, customers also need to check out the various data ofaluminium roll according to their production purpose. haomei Aluminum group produces aluminium rolls for sale of different parameters to meet your different requirements on aluminum roll stock.

In automotive materials, aluminum alloys have become the first choice for replacing traditional steel materials because of their low density, corrosion resistance, and high strength. China’s aluminum alloy auto board industry started relatively late, coupled with high-tech and capital barriers in the aluminum alloy auto panel industry, and domestic aluminum alloy panel production capacity growth is slow. At present, automotive aluminum products are mainly used in China’s auto industry to import. The Japanese automobile segment is mainly imported from Japan, while the U.S. and German automobile segments are from European companies such as Alcoa, Hydro, and others. China’s aluminum alloy auto plate manufacturers are not capable of supplying large-scale joint ventures and small plate production because of their unstable production and quality. Their products are mainly supplied to local car companies.   mirror polished aluminum sheet Automotive aluminum have obvious energy-saving effects in terms of weight reduction, but also meet the development trend of safety, environmental protection, and automotive materials, with significant economic and social benefits. As the automobile body plays a decisive role in the vehicle, the development of high performance and distinctive automotive body panels is an important part of the automotive lightweight process. Haomei aluminium has developed a new material automotive aluminum sheet. The main materials used 5000 series and 6000 series aluminum, low manganese and non-heat-treatable alloy characters and good formability and corrosion resistance. The current automotive body panels are not widely used aluminum alloy mainly because of the price of aluminum alloy Steel is about 2 times higher and stamping is more difficult. However, with the continuous development of science and technology, these issues will be well resolved. By virtue of good product quality and perfect overseas services, Haomei . has obtained stable market sharing in United State and UK, after a long-term strategic planning. We strived to obtain more international markets and our products are sold worldwide, such as Brazil, Chile, Mexico, Germany, Italy, Bulgaria, Czech, Saudi Arabia, UAE etc more than 40 countries. The share of foreign trade grows rapidly.   Why does 6061 t6 aluminum is the the most popular in the market Posted by: askaluadmin - 05-02-2018, 09:22 AM - Forum: aluminium faq - No Replies 6061T6 aluminum sheet, as a heat treatable aluminum plate, has strong plasticity. It plays an important role in mold making, aluminum bodywork and so on. Therefore, analyzing the characters of 6061 t6 aluminum alloy is necessary for the aluminum industry in the lightweight development. 6061 aluminum plate First, the national standard elements of 6061 t6 aluminum sheet produced by haomei aluminum: SI0.4-0.8, FE0.7, CU0.15-0.4, MN0.15, MG0.8-1.2CR0.04-0.35, ZN0.25 TI0.15.AL is the margin. From the perspective of its composition, MG and SI elements account for a relatively large proportion, so the 6061T6 aluminum plate is determined from the composition to have a better rust prevention effect and a stronger hardness. Although the MG content is not as high as that of the 5083 aluminum plate, the6061 alloy aluminum sheet is used as a heat-treatable aluminum plate and is processed into a T4 or T6 state by rapid quenching at a high temperature. Hardness will rise sharply. In mold cutting, numerical control panels and other practical applications will have a relatively high strength. Second, 6061T6 aluminum sheet of haomei  aluminum also has higher tensile strength in terms of performance, greater than or equal to 290. The elongation after fracture shows an increasing trend with increasing thickness. The yield strength is not less than 240 and the HV hardness is above 95 degrees   Why is the aluminium coil so popular? Posted by: ircasodle - 04-28-2018, 08:01 AM - Forum: aluminium faq - Replies (1) Aluminum coil is actually thin aluminum sheet, while to the delivery, it can be flat as sheet, it can also be rolled as coil. As the iron does not have anti-rust effect, so the aluminum has been completely replaced iron currently. Aluminum coil is one of the more commonly used products in the aluminum plate products. HAOMEI Aluminum now produce 1060,3003 and other series aluminum coil. The aluminum coil products are with beautiful appearance, smooth surface, they are used the pipe insulation package. At present main supply to power plants and chemical plants and other insulation projects. Why is the aluminium coil so popular? Now the most commonly used aluminum coil thickness is 0.4mm, 0.5mm, 0.7mm, 0.8mm, the thickness tolerance is + -0.02mm. Of which 1060 pure aluminum material is basically choose by 80% of the project, and 3003 aluminum coil belongs to the aluminum-manganese alloy, anti-rust performance will be better, so it is used in high corrosion requirements, corrosive environment projects, such as chemical plant desulfurization insulation Items and so on. Thealuminum coil gradually replace the metal as the new favor of insulation materials recently, then what are the characteristics and advantages of aluminum coil products? 1,Light weight and materials saving. Aluminum coil has light weight (steel weight is 3times of aluminum). Accounting for the price per square meter, the price of steel and aluminum is almost equal. 2,Easy construction and high efficiency. Aluminum coil is easy processing molding, construction is convenient and quick, the construction staff will reduce the labor intensity. 3,Good appearance and effect. Aluminum coil is beautiful, with aluminum coil as outside insulation decoration, the bright visual effect is very good. 4,Long using period and cost savings. Aluminum coil has long using period, because of corrosion resistance of aluminum, generally the aluminum coil will not be corroded within 20 years.
