C52100 (CuSn8) Phosphor Bronzewhich is 8% tin bronzedistinguished by a very good combination of strength and electricalconductivity. It is used for connector and current-carrying springs incontacts. Among the 4-8% tin bronze C52100 exhibits the lowest electricalconductivity, the highest reachable strength is significantly higher thanC51100 and C51000 and C51900. By means of an additional further tempering afterthe cold forming process the bendability can be further improved.In addition,it has better corrosion resistance and good sliding properties.
