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.
Temper: O, 1/4H, 1/2H, H, EH,SH
