Aluminium 7075 Bars primarily consist of aluminium alloyed with zinc (5.1%–6.1%), magnesium (2.1%–2.9%), copper (1.2%–2%), along with small amounts of chromium, manganese, iron, silicon, and titanium. This unique chemical makeup gives these bars one of the highest strength levels among aluminium alloys. Mechanically, 7075 boasts excellent tensile and yield strength, good fatigue resistance, and moderate ductility, all while remaining lightweight and easy to machine. These characteristics make Aluminium 7075 Bars perfect for high-performance applications that require both durability and precision.
