6061 Aluminium Sheet
Aluminium 6061 Sheet is a precipitation-hardened aluminium alloy, containing magnesium and silicon as its major alloying elements. Originally called "Alloy 61S".
6061 Aluminium Sheet is a medium to high strength heat-treatable alloy with a strength higher than 6005A. ASTM B209 6061 Aluminium Sheet has very good corrosion resistance and very good weldability although reduced strength in the weld zone. It has medium fatigue strength. It has good cold formability in the temper T4, but limited formability in T6 temper. Not suitable for very complex cross sections.
Core features
High strength and light weight
6061 aluminum alloy has the characteristics of high strength and light weight, its tensile strength can reach 290 MPa, the yield strength is 241 MPa, and the elongation is 8%-12%.
Good corrosion resistance
It has good corrosion resistance in most environments, especially in corrosive environments such as seawater.
Excellent processability
Easy to cut, form, and weld, suitable for various machining processes such as milling, drilling, stamping, etc.
Heat-treatability
Its strength and hardness can be improved by T6 treatment, which is suitable for applications with high performance requirements.
