6063 Aluminum Extrusion Rod Bar T6 T651
Extruded aluminum round bars 6063 T6 and T651 both belong to the Al-Mg-Si series of aluminum alloys, known for their excellent extrusion performance, corrosion resistance, and surface treatment properties. The main differences between the two lie in their heat treatment processes and mechanical characteristics. 6063 T6 is produced through solution heat treatment followed by artificial aging, but without stress relief, resulting in relatively high residual stress. In contrast, 6063 T651 undergoes an additional 1% to 3% controlled stretching after the T6 process, which relieves about 80% of the internal stress through plastic deformation, providing greater dimensional stability.
