List of copper alloys
A catalog of copper-based metallic materials, including brasses, bronzes, and other alloy families, grouped by composition or common use.
Brass: A copper–zinc alloy family whose properties vary with zinc content and other additions. Brasses form one of the largest and most familiar families in the catalog.
Admiralty brass: A tin-bearing brass developed for improved resistance to seawater corrosion. Its marine service exemplifies how a small alloy addition can target a use environment.
Gunmetal: A copper alloy, commonly containing tin and zinc, historically used for guns, valves, and fittings. Its composition and naming sit between traditional bronze and brass classifications.
Bronze Age: A period in which bronze tools and weapons became central in many societies, at different times across regions. Bronze alloys gave the catalog's oldest major family its historical prominence.
Copper Development Association: A trade association that publishes technical information and alloy designations for copper and copper alloys. Its designation system helps identify the materials represented by catalog entries.
Bronze: A copper-alloy family traditionally based on tin, with modern varieties containing other elements. Bronzes are a major family alongside brasses, despite the name covering varied compositions.
Naval brass: A manganese-bearing, tin-containing brass used in marine fittings and hardware. It is a catalog entry associated with stronger marine components than ordinary brass.
Red brass: A copper–zinc alloy with relatively high copper content, often containing small amounts of tin or lead. It contrasts with yellow brasses through its higher copper proportion and color.
Arsenical bronze: An early copper alloy strengthened by arsenic, produced before or alongside widespread tin bronze. It shows that bronze alloying began with compositions different from modern standard definitions.
Unified Numbering System: A system of alphanumeric designations used to identify metals and alloys in North America. Its copper-alloy numbers provide standardized identifiers beyond informal alloy names.
