Phosphor Bronze Strips CuSn4, CuSn8, CuSn4-4-4 Rods
1. CuSn4 - UNS.C51100 Phosphor Bronze StripsC51100 Details & Applications
CuSn4 - UNS.C51100 Phosphor Bronze Alloys, with a nominal composition of 95.60% copper and 4.2% tin, deoxidized with phosphorus, possesses mechanical properties and fabricating characteristics similar to Phosphor Bronze 5% - C51000 alloy but with 35% higher electrical and thermal conductivity by virtue of the lower tin content. C51100 alloy also offers a combination of high strength and ductility, excellent spring properties, good bearing qualities and wear resistance, excellent corrosion resistance and good resistance to stress relaxation. The improved electrical conductivity as compared to UNS.C51000 allows for miniaturization of electric current-carrying contacts and connectors.2. CuSn8 - UNS.C52100 Phosphor Bronze StripsC52100 Details & ApplicationsCuSn8 - UNS.C52100 Phosphor Bronze Alloys, which is a 8% 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 C52100 exhibits the lowest electrical conductivity, the highest reachable strength is significantly higher than C51100 and C51000 and C51900. By means of an additional further tempering after the cold forming process the bendability can be further improved.
In addition, it has better corrosion resistance and good sliding properties. C52100 is used for springy components and sliding elements when increased strength and wear-resistance are required. 3. CuSn4Zn4Pb4 - UNS.C54400 Free Cutting Phosphor Bronze RodsC54400 Details & Applications
C54400 Phosphor Bronze AlloysCuSn4Zn4Pb4 - UNS.C54400 Phosphor Bronze Alloys, is the finest bearing alloy that the industry has to offer, it is a lead-containing multi-alloy bronze exhibiting a very good machinability, it is furthermore distinguished by its excellent spring properties. C54400 is used for electrical contacts
