  • Description: A356 is commonly heat treated. We typically always use A356.2 aluminum alloy. A356.2 (original material direct from smelter) contains improved mechanical properties. A356.2 offers more strength, ductility and elongation. Typically this alloy is used in castings for aircraft parts, pump housings, impellers, high velocity blowers and structural castings where high strength is required. It can also be used as a substitute for aluminum alloy 6061. The trade off is typically A356.2 is more expensive than 356.1. Consequence of exceeding impurity limits. High copper or nickel decreases ductility and resistance to corrosion. High iron decreases strength and ductility.
