Comparison of Copper Alloys - Spring Wire Properties

Copper-base alloys are important spring materials because of their good electrical properties combined with their good resistance to corrosion. Although these materials are more expensive than the high-carbon and the alloy steels, they nevertheless are frequently used in electrical components and in subzero temperatures. All copper-base alloys are drawn to the American wire gage (same as Brown & Sharpe gage) and are nonmagnetic.
