| Symbol (Alloy) | Service Properties Copper Alloys | Applications |
|---|---|---|
| CuZn30 | 70/30 Brass. Maximum ductility of the Cu - Zn alloys Often chosen for deep drawing |
AMMUNITION SHELLS, LIGHT FITTINGS, CONNECTORS, SWITCHES |
| CuZn33 | A good cold working alloy | SHIMS, DECORATIVE GOODS, BELLOWS, CONTACTS, SPRINGS, RFI SHIELDING |
| CuZn37 | General purpose alloy for the more normal types of forming | |
| CuSn5 | Good formability combined with resistance to corrosion and fatigue | SPRINGS, INSTRUMENT COMPONENTS, CONTACTS, CONNECTORS, BELLOWS |
| CuSn6 | Extra tin giving improved wear resistance. Generally used for more severe service conditions than CuSn5 | |
| CuNi10Zn27 CuNi12Zn24 CuNi18Zn20 CuNi18Zn27 |
Alloys notable for their good corrosion resistance and attractive colour. The range of alloys becomes progressively whiter with increased nickel content. Excellent cold formability, readily soldered or brazed. | SPRINGS, CONTACTS, CONNECTORS, RFI SHIELDING, JEWELLRY, COINS |
| (Alloy 194) | For applications requiring excellent formability plus high strength and conductivity. Good resistance to softening. | LEADFRAMES, SPRINGS, CLAMPS, CIRCUIT BREAKER COMPONENTS, TERMINALS, RELAYS AND SWITCH SPRINGS, BELLOWS |
| CuNi9Sn2 | Excellent formability and resistance to corrosion in sea water. |
