Characteristics

6061 is a heat-treatable grade widely used in light to medium strength structural applications. The alloy has good corrosion resistance and weldability and possesses good formability in the 0 to T4 tempers. 6061 does lose appreciable strength when welded and it is replaced by the 5000 series alloys where afterweld strength is a prime consideration.

Typical Applications

6061 is used in structural areas where both strength and corrosion resistance is required, truck bodies and frames, and towers.
