Aluminum Alloys

Foundry Alloys

 Aluminum alloys are mixtures of it with other metals, often with copper, zinc, manganese, silicon, or magnesium. They are much lighter and more corrosion resistant than plain carbon steel, but not as corrosion resistant as pure aluminum. Bare aluminum alloy surfaces will keep their apparent shine in a dry environment due to the formation of a clear, protective oxide layer. 

Most commonly poured Alloys shall be at least 356.1, 356.2, 319, 713 and Zamak. In our aluminum foundry we have the ability to pour many other aluminum alloys as required. For more information go to aluminum casting specifications.
