Manganese Bronze Casting Alloy by the Pound Jump Ring Makers repeatable center marksJewelers Manganese Bronze is a casting alloy developed to provide jewelry casters with a base metal suitable for both centrifugal and vacuum casting applications. When properly finished, this alloy produces a bright lemon yellow color, making it an attractive option for base metal jewelry production. It is a proprietary formulation composed of approximately 60% copper (Cu) and approximately 35% zinc (Zn), with small amounts of additional metals.
