Copper and Copper Alloys


Copper and Copper Alloys have excellent electrical and thermal conductivities, are easy to fabricate and include some alloys of exceptional strength and corrosion resistance. They can be formed into complex shapes by drawing and cold heading.

Copper is available in varying purity, the best being oxygen free copper in which the extra purity enhances ductility and avoids hydrogen embrittlement during brazing.

Copper Alloys

cooper-alloys-brassBrass (Copper-Zinc Alloys)

Brass has superior cold working strength but suffers reduced conductivity.


copper-alloys-ph-bronzePhosphor Bronze (Copper-Tin Alloy)

Phosphor bronze can be significantly hardened by cold working and provide excellent spring properties.


copper-alloys-nickel-silverNickel Silver (Copper Nickel Tin Alloy)

Nickel silver does not contain silver, but has a silvery appearance. It can be hardened and is used where surface finish is important.


copper-alloys-becopperBeryllium Copper

Beryllium copper are precipitation hardening alloys of great strength and fatigue resistance making them ideal for spring applications.
