7075 Aluminum Forging

Last Updated: 2023-04-20

Prodsuct Description

Aluminum 7075 is a zinc, copper, and magnesium containing alloy capable of superior strength and stress corrosion cracking resistance. AL 7075 is an excellent material for use in highly stressed structural applications and is popular in the aerospace, military, and defense spaces. This alloy is also used for many consumer prodsucts including keys and bicycle components, and sporting equipment.

Chemical Composition


Prodsuct Properties

Aluminum 7075 is the major forging alloy in 7000 Series and Zinc is the major alloying element in this series. Aluminum 7075 forgings possess high static strength and is used in airframe structures and for highly stressed parts. Aluminum 7075 forging is available in several types of tempers such as T6, T651, T73, T7351 and T76.

T6 temper has the highest strength but lowest toughness and resistance to stress-corrosion cracking. Since toughness decreases with a decrease in temperature, the T6 temper is not generally recommended for cryogenic applications. The T73 temper provides much improved stress-corrosion resistance over T6 temper with a decrease in strength. The T76 temper provides improved exfoliation resistance and limited stress corrosion resistance over T6 temper with some decrease in strength.

Prodsuct Application

Commonly used in the manufacture of aircraft and other aerospace applications not requiring the corrosion resistance
