C51900(CuSn6) Phosphor Bronzewhich is a 6% tinbronze distinguished by a very good combination of strength and electricalconductivity. It is used for connector and current-carrying springs incontacts. Among the 4-8% tin bronze C51900 exhibits a high electricalconductivity, the highest reachable strength is significantly higher thanC51100 and C51000. By means of an additional further tempering after the coldforming process the bendability can be further improved.Typical applications Sleeve Bearings, Thrust Bearings,Screw Machine Products, Bearings, Thrust Washers
