A356 Alloy Casting

Ermak specializes in aluminum alloy casting. Some of the more common aluminum alloys are A356 / 356 / 333 / C355 / 319 / 535 / and 713. A356 aluminum alloy consists of 92.05% aluminum, 7% silicon, 0.2% iron, 0.2% copper, 0.35% magnesium, 0.1% zinc and 0.1% manganese. This alloy is lightweight and extremely corrosion-resistant, like stainless steel. The A356 alloy is typically heat-treated to add to its strength characteristics. A356, like the 356 aluminum casting alloy, has excellent casting and machining characteristics. Many parts and products made with A356, including aircraft parts, pump housings, impellers, high-velocity blowers, structural castings, machine parts, tools, and frames, have excellent strength.


At Ermak Foundry & Machining, we specialize in casting a variety of nonferrous metals and metal alloys, including the 356 alloy. We handle casting jobs from one to thousands of pieces between half an ounce to over 250 pounds.
