ASTM 6262 Aluminum Alloy – Grade B483, T6/T62 – High Strength, Excellent Machinability
ASTM 6262 is a free-machining alloy that offers users outstanding mechanical strength and good resistance to corrosion. Aluminum ASTM 6262 is heat treatable and due to the addition of bismuth is easily machinable. Anodizing raises the levels of corrosion resistance and with high-speed tooling you can achieve a smooth finish. Welding of Aluminum ASTM 6262 is achieved through gas, arc, and resistance methods. The most common tempers of ASTM 6262 are T6 and T9.
