White metal
- This article is about metals and alloys. For the music genre, see Christian metal.
The white metals are also any of several light-colored alloys used as a base for plated silverware, ornaments or novelties, as well as any of several lead-base or tin-base alloys used for things like bearings, jewellery, miniature figures, fusible plugs and metal type.
Some of the metals that make up a white metal alloy are antimony, tin, lead, cadmium, bismuth, and zinc. Not all of these metals are found in all white metal alloys but are mixed to achieve a desired goal or need. An example would be for jewellery. You would need it to be castable, polishable, have good flow characteristics, have the ability to cast fine detail without a excessive amount of porosity and cast at between 230°C and 300°C (450°F and 575°F).
