C51000 Phosphor Bronze "5% A"
Short Description:
EN equivalent CuSn5
ASTM B139, QQ-B750, SAE J461
C51000 Phosphor Bronze alloy possess a higher yield strength than is readily available in most cast products. Typical applications for phosphor bronze include bearings, bushings, gears, pinions, shafts, thrust washers and valve parts. C51000 Phosphor bronze can be readily brazed or soldered. Capacity for being cold worked is good.
