Phosphor-bronze, made with a large percent of tin compared with the amount of phosphorous, is especially resistant to fatigue and corrosion. It has high tensile strength, high capacity to absorb energy, and wear resistance. Phosphor-bronze has good thermal and electrical conductivity, though not as high as beryllium-copper. The most popular phosphor-bronze composition is 95% copper, 4.75% tin, and 0.25% phosphorous.
