What metals are used in Gravity Die Casting?

The metals that tend to be used in gravity die casting are non-ferrous alloys. Examples of metals that are seen as non-ferrous are aluminium, copper and zinc (these metals are also frequently used in gravity die casting). Because they do not contain iron, they have a higher resistance to corrosion or rust. This makes them perfect for outdoor applications. They are also not magnetic, which is helpful for electronic applications.
