AA 6262 Aluminum Alloy – High Strength, Easy Machining & Superior Corrosion Resistance

AA 6262 is a free-machining alloy that offers users outstanding mechanical strength and good resistance to corrosion. Aluminum AA 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 AA 6262 is achieved through gas, arc, and resistance methods. The most common tempers of AA 6262 are T6 and T9.
