Aluminum 6060 T5, T6, T4 – Material 3.3206 – AlMgSi0.5 (AlMgSi)
Aluminum 6060 (3.3206) is a typical Al-Mg-Si extruded aluminum alloy, slightly weaker than AA6063, suitable for applications without special strength requirements and can produce finished profiles with very good surface quality. 6060 aluminum has good corrosion resistance, moderate strength and good weldability and is commonly used in fabricated structures. The tempering design of aluminum mainly includes 6060-T5, T6, T66, T4, etc.
6060 Aluminum Alloy was registered in 1972 by the European Aluminum Association (EAA), which is widely used in Europe (especially Germany) but less so in the United States (some ASTM specifications for aluminum alloys do not even list this alloy).
