High Performance Alloys (Bronze)

Technical Information on Lead Gunmetal Bearing Bronze

Composition	:	(C83600 / LG2 / SAE 40 / CuSn5ZnPb / BC6C) Copper (Cu) Bal % Tin (Sn) 4~6% Lead (Pb) 4~6% Zinc (Zn) 4~6% Phosphorous (P) 0.05% max Aluminium (Al) 0.005% max
Applications		Pressure tight requirements, valve Bodies, pump bodies.

Technical Information on Phosphor Bronze

Composition	:	(C51900 / C5191 / CuSn6) Copper (Cu) Bal % Tin (Sn) 5.5~7% Phosphorous (P) 0.03 ~ 0.35%
Applications		Tin increases the corrosion resistance and strength while phosphorous increases the wear resistance and stiffness.Superb spring qualities, high fatigue resistance, excellent formability and solderability, and high corrosion resistance.Ideal for springs, contacts, bearing plates, fuse clips.

Technical Information on Aluminium Bronze

Composition	:	(C95810 / 958C / AB2 / CuAl10Fe5Ni5) Copper (Cu) min 79% Lead (Pb) 0.03% max Nickel (Ni) 4~5% Iron (Fe) 3.5~4.5% Aluminium (Al) 8.5~9.5% Silicon (Si) 0.1% max Manganese (Mn) 0.8~1.5%
Applications		Exceptional corrosion resistance, high strength, toughness and wear resistance. Used for heavy duty sleeve bearings, and machine tool ways.

Technical Information on Phosphor/Tin Bronze (PB1)

Composition	:	(C90710 / 904D / CuSn10 / PB1) Copper (Cu) Bal % Tin (Sn) 10~12% Lead (Pb) 0.25% max Nickel (Ni) 0.1% max Iron (Fe) 0.1% max Zinc (Zn) 0.05% max Phosphorous (P) 0.5~1.2% Aluminium (Al) 0.005% max Silicon (Si) 0.005% max Sulfur (S) 0.05% max
Applications		High wear resistance and well known for its corrosion resistance. Used in gears, piston rings, valves, bearings, heavy load bushes.

Technical Information on High Leaded Tin Bronze

Composition	:	(C93200 / ASTM B505 / B271 / SAE 660) Copper (Cu) 81~85% Tin (Sn) 6.5~7.5% Lead (Pb) 6~8% Nickel (Ni) 1% max
Applications		Lead is added to improve machinability and pressure tightness. Suitable for pump, valve components, general utility bearings, bushings.

Also available are C93700 (SAE 64/LB2) and Manganese Bronze C86300 (SAE 430B)
