The term "bronze" broadly refers to Copper alloys in which the major alloying
element is neither Zinc (which forms brass) nor Nickel (which forms Copper-
Phosphor Bronze C51000 (CuSn5) is a Tin Bronze that contains Copper, Tin and
Phosphorous. The Tin increases corrosion resistance and strength, while the
Phosphorous increases wear resistance and stiffness.
Phosphor Bronze alloys are best known for their elastic properties, and are often used
for spring-loaded electrical contacts, various electrical connectors, sleeve
bushings, clutch discs, and fasteners. C51000 brazes and solders extremely well
and has excellent cold working capacity.

Phosphor Bronze C51000 Details
Phosphor Bronze C51000 (CuSn5) is a tin bronze with the addition of 5% tin and 0.2% phosphorus for deoxidation. The tin increase the strength of the alloy and gives good corrosion resistance in marine environments.
C51000 is one of the most widely used phosphor bronzes, owing to its unique combination of properties.
The alloy offers an optimised combination of engineering properties, such as high strength and ductility, excellent fatigue and spring characteristics coupled with good corrosion resistance. It has excellent bearing properties with a low coefficient of friction and high wear resistance.
In addition, it has good cold forming properties and spring properties with excellent resistance to stress relaxation.
The alloy has an adequate electrical and thermal property, which helps it find applications in current carrying and heat transfer applications.
C51000 has superb cold working characteristics, which enables the alloy to be supplied in the half hard, fully hard, spring and extra spring conditions.
It can be joined by soldering, brazing and considered good to be joined by carbon arc welding or gas shielded arc welding; it has a machinability rating of 20% compared with free machining brass at 100%.
