C51900 Bronze Strip 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.
CuSn6 Phosphor Bronze Strip is an alloy with copper, tin and phosphorus as the main alloying elements. It has slightly higher strength properties to C5100 Phosphor Bronze while maintaining the same electrical conductivity of 15 percent IACS.
