CuSn6 strip, sheet,phosphor bronze
Detailed information
C51900/ CuSn6 Phosphor Bronze, which is a 6% 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 C51900 exhibits a high electrical conductivity, the highest reachable strength is significantly higher than C51000. By means of an additional further tempering after the cold forming process the bendability can be further improved.
Due to the higher strength and springiness and good workability, C51900 is used for all types of springs as well as for flexible metal hoses.
