What is an alloy? The term “alloy” originates from the Latin word “alloying,” which means “to mix.” Alloys are metal mixes in this sense. An alloy is a solid solution of one or more metals in which the component metals’ distinctive characteristics are preserved and not destroyed by chemical reaction.
Aluminum casting alloys are the most versatile of all common foundry alloys and generally have the highest castability ratings. As casting materials, aluminum alloys have many favorable characteristics.
Some of the more common aluminum alloys that Ermak pours are A356 / 356 / 333 / C355 / 319 / 535 / and 713.
