CuSn5 - UNS.C51000 Phosphor Bronze Strips
C51000 Details & Applications
CuSn5 - UNS.C51000 Phosphor Bronze Alloys, with a nominal composition of 94.80% copper
and 5.0% tin, deoxidized with 0.2% phosphorus is the most widely
used of the phosphor bronzes, which offering an optimum
combinations of such engineering properties as high strength and
ductility, superior fatigue and spring characteristics, excellent
corrosion resistance, durability for severe service, good bearing
qualities with low friction and higher wear resistance, superior
forming and spinning, resistance to stress relaxation and good
joining properties. In most cases, C51000 alloy has adequate
electrical and thermal properties for many current-carrying and
heat transfer requirements.
C51000 Alloy typical applications for phosphor bronze include
bearings, bushings, gears, pinions, shafts, thrust washers and
