Aluminium 7075 Angles & Flats

Aluminium Alloy 7075 Angles & Flat belong to a class of high-strength aluminum alloys renowned for their exceptional strength-to-weight ratio, impressive mechanical properties, and suitability for aerospace and high-performance applications. Distinguished by a specific chemical composition, Aluminium Alloy 7075 is revered for its ability to withstand heavy loads and harsh conditions.

The chemical composition of Aluminium Alloy 7075 includes approximately 1.2-2.0% zinc, 2.1-2.9% magnesium, and traces of other elements such as copper and chromium. This composition imparts remarkable strength, making it one of the strongest commercially available aluminum alloys. The alloy's combination of zinc and magnesium contributes to its high tensile strength and fatigue resistance, allowing it to withstand dynamic loads and stress.

The standout feature of Aluminium Alloy 7075 Angles & Flat is its unparalleled strength, making it an optimal choice for applications demanding robust mechanical properties. Its impressive strength-to-weight ratio and exceptional hardness render it suitable for aerospace components, including aircraft structures, fuselages, and wing spars. Additionally, it finds use in high-performance sporting goods, such as bicycle frames and climbing equipment, where strength and lightweight design are paramount.

Heat treatment plays a crucial role in optimizing Aluminium Alloy 7075's mechanical properties. It is often solution heat treated and artificially aged to enhance its strength and hardness for specific requirements. This heat treatment regimen increases its strength while maintaining its toughness.

Aluminium Alloy 7075 offers good resistance to stress corrosion cracking and has acceptable general corrosion resistance. However, compared to other aluminum alloys, it may be less resistant to certain corrosive environments. Protective measures such as anodizing or coatings are advisable in applications where corrosion is a concern.
