7075 aluminum is a high-strength aluminum alloy that’s often used in aerospace, automotive, and military applications. Known for its exceptional properties, it offers a combination of strength, durability, and corrosion resistance. Here are some of the main characteristics of this alloy.

High Strength

One of the most notable characteristics of 7075 aluminum is its high strength. It’s one of the strongest aluminum alloys available and comparable to many steels. This makes it ideal for applications where high structural strength is needed without the weight of steel.

Excellent Hardness

7075 has excellent hardness, which enhances its wear resistance. This makes it suitable for parts that are subject to high stress and wear, such as gears, shafts, and military-grade equipment.

Good Fatigue Resistance

This alloy has superior fatigue resistance, which means that it can withstand repeated stress and strain without failure. This is important for aerospace and automotive parts that experience cyclic loading, such as wing spars and suspension components.


7075 is relatively lightweight. It has a great balance of lightness and strength, which is especially useful in applications where weight reduction is critical, such as in aircraft and performance vehicles.

Corrosion Resistance

7075 offers good corrosion resistance, especially when treated with a protective coating or anodization. This resistance to corrosion makes it suitable for use in harsh environments where exposure to moisture and chemicals is a concern.

High Thermal Conductivity

The alloy has high thermal conductivity, which is beneficial in applications requiring efficient heat dissipation, such as heat sinks and radiators.

7075 aluminum is also used for its machinability, ductility, and malleability. These features help make it a top choice for a wide range of applications.
