Aluminium alloy 6061 is a medium to high strength heat-treatable alloy with a strength higher than 6005A. It 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.
Aluminum Sheet 6061 T6/T651 is highly versatile and normally used for aerospace, marine, electronic, ornamental, machinery, and structural applications. 6061 aluminum has a high strength-to-weight ratio, above average corrosion resistance, good machinability, and is excellent for welding. An advantage of 6061 aluminum sheet is that it is easy to machine and popular for metal fabrication.
