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, 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 porosityIn geology, the porosity of a rock or sediment is the proportion of the non-solid volume to the total volume of material, and is defined by the ratio: : where V is the non-solid volume ( pores and liquid) and V is the total volume of material, including t and cast at between 230° CThe degree Celsius (°C) is a unit of temperature named after the Swedish astronomer Anders Celsius ( 1701 1744), who first proposed it in 1742. The Celsius temperature scale was designed so that the freezing point of water is 0 degrees, and the boiling po and 300°C (450° FThis article is about the temperature scale; see also Fahrenheit graphics API. Fahrenheit is a temperature scale named after the German physicist Gabriel Fahrenheit ( 1686 1736), who proposed it in 1724. In this scale, the freezing point of water is 32 de and 575°F).
