Product Overview
Description
Material introduction:C5210(CuSn8)
CuSn8 - UNS.C52100 Phosphor Bronze Alloys, which is a 8% tin bronze distinguished bya 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 /C51000 / C51900. By means ofan 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.
