Aluminium Alloy 7075 Powder

Aluminium Alloy 7075 is widely regarded as one of the strongest aluminum alloys available, with remarkable mechanical properties, excellent resistance to stress, and a high strength-to-weight ratio. The alloy is primarily composed of zinc (Zn) as the main alloying element, with smaller amounts of magnesium (Mg), copper (Cu), chromium (Cr), and zirconium (Zr).

Key Properties

High Strength

One of the defining characteristics of Aluminium 7075 is its exceptional strength. It boasts a tensile strength of up to 700 MPa, which makes it one of the strongest aluminum alloys available. This strength is essential in industries like aerospace, where components must withstand high stress and mechanical forces while maintaining structural integrity. The alloy’s high strength allows it to perform in challenging environments, including high-stress applications like aircraft wings, structural supports, and landing gear.

Excellent Fatigue Resistance

Aluminium 7075 exhibits outstanding fatigue resistance, which means it can endure cyclic loading and repeated stress without compromising its performance or failing prematurely. This makes it an ideal material for aerospace components, automotive parts, and military equipment, where repetitive forces and vibrations are often encountered. The alloy’s fatigue resistance ensures long-term durability, making it a preferred material for parts that are exposed to fluctuating loads and stresses over time.

Corrosion Resistance

Although not as corrosion-resistant as some other aluminum alloys, Aluminium 7075 provides adequate protection against atmospheric corrosion, particularly in dry environments or mild marine conditions. The alloy’s resistance to corrosion is further enhanced through processes like anodizing and coating, which help improve the longevity of parts exposed to harsh conditions. This makes it suitable for use in marine, aerospace, and defense applications, where exposure to moisture, salt, and other corrosive elements is common.
