Hot Forming Aluminum Sheet

Welcome to the latest how to installment from jay roche at special 79 barnstorm cycles.

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. Hot forming of al mg alloy sheet 1. The 7000 series aluminium alloys has best potential to be used for the structural components in the car. Hot forming aluminum if you bend anything harder than 5054 aluminum you will need to anneal it by heating along the bend line.

If you don t such hard aluminum will crack and break during forming. Hot draw forming the hot forming process is similar to traditional cold forming but involves heating the tool and component. Quenching in the closed cooled die. 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. The hot sheet metal is brought into contact with the hot die whilst the hot punch descends into the die and shapes the part. Intergranular cavitation occurred at temperatures above 300 c 572 f at strain rates less than 1 x 10 2 s 1. 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. 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 pattern of warm forming behavior previously established for aluminum magnesium alloys deformed at temperatures.

The hot forming process consists of the following steps. Usually a diamond shaped mesh is preferred as it has a structural advantage over other shapes. Transfer from furnace to press and drawing tool. Heat treatment in furnace.

The 7000 series has bad formability at room temperature both 5000 and 6000 series also have. 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. Grain growth occurs.
