Hot Forming Aluminum Sheet

Aluminum melts between 865 and 1 240 degrees f so you obviously can t heat it as much as steel.

Hot forming aluminum sheet.

In this metal forming process a sheet of metal is passed through perforating scissors where it is cut and stretched into a pattern. Transfer from furnace to press and drawing tool. The 7000 series aluminium alloys has best potential to be used for the structural components in the car. Heat treatment in furnace.

This forming process is commonly used for manufacturing fences catwalks platforms grating etc. The hot forming process consists of the following steps. 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. The 7000 series has bad formability at room temperature both 5000 and 6000 series also have.

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. The part is then held under forming pressure for a period. Parts produced by hot forming are characterized by high strength complex shapes and reduced springback effects. 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.

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. Usually a diamond shaped mesh is preferred as it has a structural advantage over other shapes. The pattern of warm forming behavior previously established for aluminum magnesium alloys deformed at temperatures. Hot draw forming the hot forming process is similar to traditional cold forming but involves heating the tool and component.

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. Grain growth occurs. The hot sheet metal is brought into contact with the hot die whilst the hot punch descends into the die and shapes the part. Quenching in the closed cooled die.

Hot forming of al mg alloy sheet 1. Intergranular cavitation occurred at temperatures above 300 c 572 f at strain rates less than 1 x 10 2 s 1. 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. Temperatures range from 600 c to 980 c depending on customer specifications and the material used.
