Aluminum 6262-T8
Categories:	Metal; Nonferrous Metal; Aluminum Alloy; 6000 Series Aluminum Alloy
Material Notes:	Weldability = B; Stress Corrosion Cracking Resistance = A; General Corrosion Resistance = B (A = best; E = worst). General 6262 characteristics and uses): Good machinability and high strength; high corrosion resistance and applied coating acceptance. Finishing characteristics better than 2011, 2017, 2024, 7075 and equal to 6061. The T8 temper offers excellent residual stress control. Uses: Camera parts, couplings, marine fittings, decorative and misc. hardware, hinge pins, knobs, magneto parts, nuts, oil line fittings, appliance fittings, roller skate parts, steam iron parts, TV fittings, tripod fittings, valves and valve parts.
