Friction stir butt welding thin aluminum alloy sheets Posted by: aluminiumsheet - 08-16-2018, 07:06 AM - Forum: Knowledge & Technique - No Replies 0.8-mm-thick alclad 2024-T4 aluminum alloy sheets were friction stir butt welded. A 15-mm diameter shoulder tool was used to guarantee sufficient heat input during welding. A 0.08-mm shoulder plunge depth was adopted to reduce sheet thickness reduction. Sound joints were obtained at rotating speeds from 400 to 1000 rpm and welding speeds from 50 to 150 mm/min. A thickness reduction of 6% was achieved at 1000 rpm and 50 mm/min. Secondary phases firstly precipitated at the black lines in the stir zone (SZ). The hardness of the SZ showed a decrease about 6% compared with the base metal. A maximum tensile strength of 399.5 MPa and an elongation of 5.6% were achieved at 1000 rpm and 150 mm/min. The fracture morphologies showed typical ductile fracture mode.   What is the difference of the aluminum sheet and the aluminum foil? Posted by: lolitahe69 - 08-16-2018, 06:34 AM - Forum: aluminium faq - No Replies [img=300x0]http://www.aluminiumstrip-hm.com/wp-content/uploads/2018/04/1-300x300.jpg[/img] aluminum sheet Thickness of aluminum plate is put under more than 0.2 mm to 500 mm and 200 mm width, length less than 16 m aluminum material as aluminum plate or aluminium material, below 0.2 mm for aluminum, article within 200 mm width of row materials or materials (of course with the progress of large equipment, the most can do 600 mm wide row material also more). Aluminum plate is the rectangular plate made of aluminum ingot, which is divided into pure aluminium plate, alloy aluminum plate, thin aluminum plate, medium thickness aluminium plate, decorative Aluminium foil (or aluminum foil), often referred to with the misnomer tin foil, is aluminium prepared in thin metal leaves with a thickness less than 0.2 mm (7.9 mils); thinner gauges down to 6 micrometres (0.24 mils) are also commonly http://used.In the United States, foils are commonly gauged in thousandths of an inch or mils. Standard household foil is typically 0.016 mm (0.63 mils) thick, and heavy duty household foil is typically 0.024 mm (0.94 mils). The foil is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated to other materials such as plastics or paper to make them more useful.   Friction stir welding of thin 1050 aluminum sheet by heat assisted tool Posted by: ircasodle - 08-16-2018, 01:54 AM - Forum: Knowledge & Technique - No Replies The objective of the present study is to relieve the friction stir welding (FSW) tool from one of its main role: to generate heat by friction. 1-mm-thick 1050-H24 aluminum sheets were friction stir welded using a heater-embedded FSW tool. It is demonstrated that butt welding of the sheets becomes successful even at a low rotational speed of 60 rpm under the assist-heating of the FSW tool. The fact indicates that it is possible to weld without frictional heat. Sound joints with the highest average fracture strength, which is equivalent to that of the base metal, was obtained under the welding speed of 0.5 mm/s and the tool rotational speed of 60 rpm. The temperature of the sheet does not exceed 400 K throughout the welding under this condition. This temperature is 60 K lower than the ordinary FSW in which assist-heating is not used. One of the microstructural features in heat-assisted FSW is that the widths of heat affected zone (HAZ) and thermo-mechanically affected zone are suppressed, compared to the ordinary FSW. Particularly, HAZ becomes almost negligible. The hardness profile shows the maximum at the stir zone without revealing HAZ softening.   Mirror polishing thin aluminum sheet on both sides without warping Posted by: KamorkasOa - 08-16-2018, 01:52 AM - Forum: Knowledge & Technique - Replies (1) Hello all, We're trying to find a solution to achieve the same degree of standard grade mirror polishing on both sides of some rectangular pieces of 1 mm thick aluminium sheet, whilst retaining the flatness of the sheets. The largest piece is 1500 mm x 300 mm (5 ft x 1 ft) These will be components for an artwork we're trying to make, so lightness of material is imperative, hence aluminium. The samples we received from the local polishers were bent from stress relieving as they were made from one-sided mill finished mirror-polished aluminium which was then shop polished on the reverse side. Your thoughts would be appreciated - is electropolishing an option?   How to Solder Aluminum Sheet Metal Posted by: ircasodle - 08-16-2018, 01:30 AM - Forum: aluminium faq - No Replies Learning to solder aluminum metal sheet is a great skill to add to your DIY toolbox. Soldering is the process wherein two or more metal items are fused together by melting a filler metal into the joint. While soldering is generally easy, if become more difficult when working with certain materials. One of the most difficult materials to solder is an aluminum sheet metal because the aluminum oxide film on the aluminum sheet metal is so stable that it is very difficult to remove, even using heat from the soldering iron. Consequently, it is very difficult to solder and create strong joints on two aluminum sheet metals. This is the reason why a lot of DIY enthusiasts avoid working with aluminum sheet metal. However, here are some tricks on how to properly solder an aluminum metal sheet. Step 1 - Clean Your Aluminum Metal Sheet Use a clean rag to wipe your aluminum sheet metal from any dirt and apply a solvent or grease remover to remove oil or grease. This step is necessary the fact that when you are working with aluminum, it is very difficult to solder it properly this you need to remove any obstructions  from the metal sheet to facilitate the soldering process. Step 2 - Set the Aluminum Sheet Together Set the aluminum sheet together and ask a friend to hold both sheets firmly in place or you can use clamps to secure the aluminum sheets together. Before you proceed to the next step, make sure that you wear the necessary gear like a pair of working gloves, goggles and a long-sleeved work shirt to protect yourself from sparks. Step 3 - Apply the Flux on the Area to be Soldered The next step is to apply a flux to the areas where you need to solder. The flux is a chemical cleaning agent that facilitates the soldering process by means of removing the oxidation from the material you are working with. The flux extremely important when fusing a difficult aluminum sheet metal with another material. Step 4 - Heat the Flux and the Metal with a Torch Heat the area where you need to solder using a torch. Make sure that the solder metal or filler melts instantly. Do not apply heat directly to the solder filler to prevent the solder metal from burning up. You will know that the aluminum sheet metal has been soldered properly using the flux and solder metal if the molten filler flow onto the aluminum an seeps inside the joint but if it just rolls off, you need to try another flux and solder metal and repeat the process until you observe seepage of the metal to the aluminum joint.   Density of Aluminum and the Thickness of A thin Aluminum Sheet Posted by: ircasodle - 08-16-2018, 01:27 AM - Forum: Knowledge & Technique - No Replies Density is a property of a substance thus it can be used to identify a particular substance (Jensen 45). Density is a measure of how tightly packed particles are in matter by using the ration of mass to volume; mass and volume are related direct proportion (Mahan 20, Kalpakjian and scmid 13). Density is determined using the formula: Where M is the mass while V is the volume In this experiment, the masses and volumes of 3 samples of aluminum will be determined and be used to determine the density of aluminum. The density of the aluminum will be used to determine the thickness of the aluminum foil in the second part of the experiment. Materials Scale/balance 3 aluminum samples 25ml graduated cylinder Caliper Weighing boats Procedure 3 aluminum samples were obtained: 1 aluminum shot and 2 aluminum bars The scale was zeroed The sample was placed on the weighing scale and the mass was recorded The volume of the bar was determined using the formula Length (L)*Width (W)*Height (H) measured using a caliper The volume of the shot was determine using the water displacement method The volume of the second bar was determined using the L*W*H method The value of the density of the 3 samples was calculated using the formula:   The value of the densities was then averaged. Data and Observations Volume of the bars Sample Length L (cm) Width W (cm) Height H (cm) Volume (cm3) (L*W*H) 1 76.2 6.2 25.3 19.95275 2 5 1.2 2.5 15.00000   Volume of the Aluminum shot 67mL – 50mL = 17mL Sample Mass (g) Volume (V) Density (g/cm3) Aluminum bar 1 32.779 11.95275 2.74238 Aluminum bar 2 44.676 15.00000 2.97840 Aluminum shot 46.140 17.00000 2.71411   Rounded off average density = 2.8 g/cm3 Part II Background In science we use both large and small numbers at the same time. The laboratory tools available are not suitable for measuring the thickness of an aluminum foil. However, the volume of a regular object can be calculated using the formula: Taking the height (h) to be the thickness (T) of the foil, therefore: Using the density formula we get the volume formula The aluminum foil can be measured to get its mass and used the density obtained from part I. Materials Balance, centimeter ruler, 4 sheets of aluminum foil, data table and a calculator Procedure A data table was made to include all the necessary data A large aluminum foil was cut into 4 pieces with 900 edges The length and width of each piece was measured and recorded The mass of each piece was measured and recorded Calculations were made           I want to be able to weld thin aluminum sheet Posted by: ircasodle - 08-16-2018, 01:22 AM - Forum: aluminium faq - Replies (1)  I have zero knowledge about welding aluminum. I'm only talking about being able to weld some thin sheet aluminum together to make a cup holder for my boy's motorcycles. I also want to be able to weld together some aluminum tubing to make a luggage rack. Now...before you start trying to have me spend $2K on a welder.....Remember, I only want to do this for a few pieces and see if I like doing this. Isn't there a way to "weld" aluminum by applying heat and using a "welding rod"?? Educate me.!   Take a piece of thin aluminium sheet and keep it in the water in the bucket what do w Posted by: ircasodle - 08-16-2018, 01:16 AM - Forum: aluminium faq - No Replies Take a piece of thin aluminium sheet and keep it in the water in the bucket what do we observe? Now shape the same piece of aluminium into a small boat and place it on the surface of the water if float isn't it When we drop the aluminium sheet in the water it sinks because the density of aluminium is greater than the density of water.We can make it float by decressing its density by keeping the mass constant. Prepare a boat using the aluminium sheet and place it on the water,we observe that it float on water because the bowl has large surface area and the air present in it make the bowl float. Its density decreases when it made as a bowl.   Wrought Aluminium Alloys vs Cast Aluminum Alloys Posted by: KamorkasOa - 08-15-2018, 07:06 AM - Forum: Knowledge & Technique - No Replies It is simply to divide aluminum and aluminum alloys into two categories: wrought aluminium alloys and cast aluminum alloys. Wrought aluminium alloys contain lower percentage of elements, about less than 4%. Cast aluminum alloys contain the same chemical composition but has greater amounts. In the same temperature range( 520 to 590℃), the cast aluminum alloys undergo a thoroughly chemical properties while wrought aluminum alloys still remain the mechanical properties and remain ductile. Aluminum plate advantages: According to the rolling processing technique, cast aluminum alloys are generally divided into cold casting and hot casting aluminum alloy. The key difference is the recrystallization temperature. Aluminium Alloy Grades Aluminum alloy grates are the most basic types of aluminium sheets. According to international alloy designation system, there are mainly 8 aluminum alloy series . 1000, 4000 and 5000 aluminium alloy series are non-heat-treatable while 2000, 6000, 7000 and 8000 aluminium alloy series are heat-treatable. 8 series aluminum alloy sheet has different advantages: series 1000 alu sheet is pure industrial aluminum alloy and is lower in prices; series 3000 alu sheet is the most great type on corrosion resistance and also being called “corrosion resisting aluminum alloy”; series 2000 and 7000 alu sheet are aluminium alloy used in aircraft; 8011 alu sheet is the best aluminum foil material. In haomei Aluminum, our main types of aluminium sheets are series 1000, 3000 and 8011. Mature means of processing and casting is the quality of haomei  Aluminum aluminum sheet plate. According to your practical application, our professional staff will make a more elaborate division for you.   Types of Aluminum Sheet Finishes Posted by: KamorkasOa - 08-15-2018, 07:00 AM - Forum: Knowledge & Technique - No Replies After a series of steps, raw aluminum sheets can be processed into all kinds of profiles. The first most common kind is aluminium tread plate. It belongs to aluminum floor plate, other names including aluminum diamond plate, aluminium chequer plate, aluminium ribbed plate, etc. This kind of alu sheet usually being used in various decorations and buildings. The next common one is embossed aluminum plate. People often call them textured aluminum sheet, pressed aluminium sheets and hammered aluminum sheet, too. They are types of aluminium sheets with suppressing pattern on them. The embossed aluminum plate can also be printed various colors on the surface. So, it is widely used in the decoration industry. The next common profiles are corrugated aluminum plate or wavy aluminum sheet, they are both often used in roofs. Other aluminum sheet finishes are fluted aluminium sheet, slotted aluminum plate, polished aluminum sheet, drilling aluminum plate and so on.
