Material Properties Aluminum 6061-T6; 6061-T651

Aluminum 6061 is one of the most common alloys of aluminum for general-purpose use. 6061 is a precipitation-hardened aluminum alloy, containing magnesium and silicon as its major alloying elements. It has good mechanical properties, exhibits good weldability, and is very commonly extruded.

General 6061 Characteristics and Uses: Excellent joining characteristics, good acceptance of applied coatings. Combines relatively high strength, good workability, and high resistance to corrosion; widely available. The T8 and T9 tempers offer better chipping characteristics over the T6 temper.

Applications: Aircraft fittings, bike frames, camera lens mounts, couplings, marines fittings and hardware, electrical fittings and connectors, hardware, hinge pins, brake pistons, hydraulic pistons, appliance fittings, valves and valve parts, etc.
