Common names for brass alloys may be misleading, so the Unified Numbering System for metals and alloys is the best way to know the composition of the metal and predict its applications. The letter C indicates brass is a copper alloy. The letter is followed by five digits. Wrought brasses — which are suitable for mechanical forming — begin with 1 through 7.

Electrum Chemical Composition . Electrum consists of gold and silver, often with small amounts of copper, platinum, or other metals. Copper, iron, bismuth, and palladium commonly occur in natural electrum. The name may be applied to any gold-silver alloy that is 20-80% gold and 20-80% silver, but unless it is the natural alloy, the synthesized metal is more correctly termed 'green gold', 'gold
