CuSn8 – UNS.C52100 Phosphor Bronze Alloys

C52100 Details & Applications:
C52100 Phosphor Bronze

CuSn8 – UNS.C52100 Phosphor Bronze Alloys, which is a 8% tin bronze distinguished by a very good combination of strength and electrical conductivity. It is used for connector and current-carrying springs in contacts. Among the 4-8% tin bronze C52100 exhibits the lowest electrical conductivity, the highest reachable strength is significantly higher than C51100 and C51000 and C51900. By means of an additional further tempering after the cold forming process the bendability can be further improved.
In addition, it has better corrosion resistance and good sliding properties. C52100 is used for springy components and sliding elements when increased strength and wear-resistance are required.
