Copper alloys are primarily copper mixed with different alloying elements that produce a new range of materials designated with particular characteristics such as strength, ductility, formability, machinability, or conductivity. Copper and its alloys have excellent electrical and thermal performance with high resistance to corrosion and a relatively low price point. Copper alloys are great choices in the realm of brazing due to their excellent corrosion resistance, conductivity, and capillary action.
These alloys are grouped into the commonly named families listed below.
- Coppers – copper with trace elements
- Brasses – copper with zinc
- Bronzes – copper with tin
- Copper-Nickels – copper with nickel and manganese
- Nickel Silvers – copper with nickel and zinc

Bronze features very low metal-on-metal friction and is widely used in the production of high quality springs, bearings, bushings, and small transmission & engine parts. Bronze struck against a hard surface will not produce sparks unlike other metals, such as steel, making it quite suitable in explosive or flammable environments.
Nickel Silver is a copper alloy produced through the combination of copper, nickel, and zinc. (60% copper, 20% nickel, 20% zinc). The alloy itself contains no silver (unless plated) and is named for its silvery appearance. Its industrial and technical uses include marine fittings and plumbing fixtures for its corrosion resistance, and heating coils for its high electrical resistance.
For use in copper to copper and brass to brass (without flux). Not recommended for nickel.
