About Aluminium 7050 Flat Bars
Aluminium Alloy 7050 belongs to the 7000 series family — a group of high-strength aluminum-zinc-magnesium-copper alloys. Originally developed for the aerospace industry, 7050 was designed to provide higher strength and improved resistance to stress corrosion cracking than 7075 aluminum, particularly in thick sections.
The combination of zinc (as the primary alloying element) along with magnesium and copper gives this alloy its extraordinary mechanical properties. The T6 and T7451 tempers enhance its toughness and fatigue resistance, making it ideal for high-performance engineering environments.
In industries where weight reduction without compromising strength is a critical factor, Aluminium 7050 is the go-to choice. It provides a perfect balance of structural integrity, fatigue strength, and corrosion protection, making it suitable for long-term use under high stress or dynamic loading.
