Aluminum casting is the kind of metal working process that involves pouring liquid metal into a mold or form. Aluminum casting uses variation of aluminum and aluminum alloys as the liquid metal that is poured into the mold. Aluminum castings are used to make complex and detailed parts very efficiently.
