6061 T6 Flat Sheet Structural

6061 T6 is a heat-treatable structural aluminium alloy valued for its high strength-to-weight ratio, excellent machinability, and good weldability. It is the preferred alloy for structural framing, machine parts, jigs, fixtures, and precision engineering applications.

SD Aluminium stocks 6061 T6 flat sheet and plate in thicknesses from 1.6mm to 6mm, available in standard sizes. 6061 offers significantly higher tensile strength than 5005 or 5052 alloys, making it the right choice when structural load-bearing capacity is required.
