C54400 Continuous cast and drawn
Phosphor bronze C54400 contains copper, tin, and phosphorus. Phosphorus increases the wear resistance and stiffness of the alloy. Tin increases the corrosion resistance and strength of the alloy. Lead, zinc, and iron are other named elements. Phosphor bronze alloys are notable for their toughness, strength, good conductivity, and low coefficient of friction.
C544 also designated as as CuSn4Zn4Pb4 and CW456K.
In addition to C54400, Concast offers phosphor bronze alloys C51000, C52100, and C53400. Concast is the only domestic producer of phosphor bronze.
