7075 AEROSPACE ALUMINUM BAR
7075 is an aerospace aluminum bar with cold finished or extruded aluminum wrought alloy with high strength, adequate machinability and improved stress corrosion control. Fine grain control results in good tool wear.
7075 is one of the highest strength aluminum alloys. It has good fatigue strength and average machinability. Often used where parts are highly stressed. It is not weld able and has less corrosion resistance than other aluminum alloys. The mechanical properties depend on the temper of the material. Commonly used in the bicycle industry, aircraft structures.
When forging this metal, it is recommended that the temperature be set between 700 and 900 degrees. This should then be followed by solution heat treatment. It’s not recommended for welding to be used as a joining technique, but if needed, resistance welding can be used. It’s not recommended for arc welding to be used because it can lower the metal’s corrosion resistance.
