Die cast aluminum is a kind of aluminum wherein metals are molted under high pressure in the mold cavities. In the die casting process, the metals are hardened and the desired shapes are produced. Aluminum die casting can be made with the use of either hot chamber or cold chamber process Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter, and tin-based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used. As already mentioned, it is very strong and durable. It might not be as strong as cast iron, however, it is very close and certainly a type of metal that you can depend on when you need it the most. ... It can be purchased at a cost of about half of what you would spend on other types of metals and AL alloy.
