What is 7075 Aluminum Alloy?

7075 aluminum alloy is a high-strength material that belongs to the 7000 series of aluminum alloys. It is often used in applications that require excellent strength-to-weight ratio, such as aerospace, military, and automotive industries.

The alloy is primarily composed of aluminum, with zinc as the primary alloying element. Copper, magnesium, and chromium are also present in smaller amounts, which enhances the alloy’s mechanical properties. This alloy is precipitation hardened to improve its strength.

Some of the key properties of 7075 aluminum alloy include:

High strength: This alloy has a very high strength-to-weight ratio, making it an ideal choice for structural applications.
Excellent fatigue strength: This material has good fatigue properties and can withstand repeated loading cycles.
Good machinability: 7075 aluminum alloy can be easily machined, although it can be more challenging than other aluminum alloys due to its high strength.
Corrosion resistance: The alloy has good corrosion resistance, although it is not as good as some other aluminum alloys.
Heat treatable: 7075 aluminum alloy can be heat treated to improve its strength further.
