The performance of beryllium copper and phosphor bronze should be based on the requirements of use and use, in order to compare the required performance is good or poor. The use and requirements are not indicated above, so the main performances are listed below:
Coefficient of elasticity Thermal conductivity Electrical conductivity Tensile strength Elongation Specific gravity GPa W / m. K% IACS σb / MPa% g / cm3 phosphor bronze 110 62.3-83.8 12-19 470 8-38 8.8-8.86 beryllium copper 128 105 ≥18% 1105 1 8.3-8.4
