6061

6061 aluminium alloy is a heat-treatable alloy with medium strength, good corrosion resistance, and weldability. It is commonly used in vehicle frames, heavy duty structures, and other applications. The alloy has a tensile strength ranging from 125 MPa in the O temper to 260-310 MPa in the T6 temper. It has good machinability and fabricability properties and can be joined using various welding methods. The alloy also exhibits good corrosion resistance in industrial and marine atmospheres.
