Product Description

ISO Qualified Cusn6 Copper tin alloy Strip
Phosphor bronze factory,  more than 12 years manufacture experience, attained ISO9001, work on OEM and ODM projects..


 

1. Introduction of the C51900 CuSn6 PB103 Phosphor Bronze strip  

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.
