What are the materials for gravity die casting?

Gravity Die Casting is a manufacturing process that involves pouring molten material into a permanent mold in order to produce metal parts which are built to tight tolerances.

The molten materials can be Aluminum, Pewter (or other so called white or pot metals), Zinc or an alloy of Zinc mixed with an amount of copper and aluminum. Basically, any metals that have a lower melting point than steel can be used for Gravity Die Casting.

The permanent mold used in Gravity Die Casting is nearly always built of Steel. This Steel is usually hardened and polished to a high mirror like quality before it's put into use. The exception to Steel Molds are Graphite Molds which are used with less frequency due to the difficulty and health risks involved with machining Graphite.
