Hot Forming Aluminum Sheet

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.

Hot forming aluminum sheet.

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. Temperatures range from 600 c to 980 c depending on customer specifications and the material used. Hot forming aluminum if you bend anything harder than 5054 aluminum you will need to anneal it by heating along the bend line. Quenching in the closed cooled die.

The pattern of warm forming behavior previously established for aluminum magnesium alloys deformed at temperatures. The hot forming process consists of the following steps. 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. The 7000 series aluminium alloys has best potential to be used for the structural components in the car.

This forming process is commonly used for manufacturing fences catwalks platforms grating etc. Hot forming of al mg alloy sheet 1. 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. 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 part is then held under forming pressure for a period. Intergranular cavitation occurred at temperatures above 300 c 572 f at strain rates less than 1 x 10 2 s 1. 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. Transfer from furnace to press and drawing tool.

Grain growth occurs. Heat treatment in furnace. Aluminum melts between 865 and 1 240 degrees f so you obviously can t heat it as much as steel. Usually a diamond shaped mesh is preferred as it has a structural advantage over other shapes.

Hot draw forming the hot forming process is similar to traditional cold forming but involves heating the tool and component. If you don t such hard aluminum will crack and break during forming. The 7000 series has bad formability at room temperature both 5000 and 6000 series also have. Welcome to the latest how to installment from jay roche at special 79 barnstorm cycles.
