Hot Forming Aluminum Sheet

Hot forming of al mg alloy sheet 1.

Hot forming aluminum sheet.

Hot forming aluminum if you bend anything harder than 5054 aluminum you will need to anneal it by heating along the bend line. In hot forming of aluminum the conventional approach to harden the material is to heat it to its solution heat treatment temperature and form and cool it in the tool. Hot draw forming the hot forming process is similar to traditional cold forming but involves heating the tool and component. In this metal forming process a sheet of metal is passed through perforating scissors where it is cut and stretched into a pattern.

This tech tip is related to their sportster project but can be used on anything you might be working with that requires something built out of aluminum sheet. Parts produced by hot forming are characterized by high strength complex shapes and reduced springback effects. Aluminum materials are characterized by high stacking fault energy values meaning that a lot of deformation and energy has to be introduced in order to trigger recrystallization. This forming process is commonly used for manufacturing fences catwalks platforms grating etc.

Aluminum melts between 865 and 1 240 degrees f so you obviously can t heat it as much as steel. Intergranular cavitation occurred at temperatures above 300 c 572 f at strain rates less than 1 x 10 2 s 1. The part is then held under forming pressure for a period. Temperatures range from 600 c to 980 c depending on customer specifications and the material used.

Usually a diamond shaped mesh is preferred as it has a structural advantage over other shapes. Grain growth occurs. Therefore the mentioned rule of thumb has to be corrected towards much higher temperature values for the distinction between warm and hotforming for aluminum alloys. If you don t such hard aluminum will crack and break during forming.

To obtain the desired mechanical properties the material then needs to be artificially aged by heating it again to a certain temperature for a specific amount of time. Quenching in the closed cooled die. According to the hot blow forming method for the aluminum alloy sheet the aluminum alloy sheet is an aluminum alloy sheet composed of by mass 1 1 to 6 5 mg 0 01 to 0 3 fe and the balance. The pattern of warm forming behavior previously established for aluminum magnesium alloys deformed at temperatures.

The 7000 series has bad formability at room temperature both 5000 and 6000 series also have. The 7000 series aluminium alloys has best potential to be used for the structural components in the car. Heat treatment in furnace. The hot sheet metal is brought into contact with the hot die whilst the hot punch descends into the die and shapes the part.
