Phosphor Bronze Manufacturers

Phosphor Bronze has 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, Phosphor Bronze has adequate electrical and thermal properties for many current-carrying and heat transfer requirements.

  • C51900 Bronze Strip is a 6% tin bronze distinguished by a very good combination of strength and electrical conductivity. It is used for connector and current-carrying springs in contacts. Among the 4-8% tin bronze C51900 exhibits a high electrical conductivity, the highest reachable strength is significantly higher than C51000. By means of an additional further tempering after the cold forming process the bendability can be further improved.

  • CuSn8 Phosphor Bronze Strip possesses the best spring properties of all 500 series Phosphor Bronze. High hardness, high strength, coupled with good formability and resistance to fatigue make this alloy an excellent choice where the most severe forming and functional requirements must be met.

  • C52100 Bronze Strip its adequate conductivity makes it particularly interesting for springy conductive components. It is wear-resistant, has very good corrosion resistance and can be readily soldered.

  • CuSn6 Phosphor Bronze Strip is an alloy with copper, tin and phosphorus as the main alloying elements. It has slightly higher strength properties to C5100 Phosphor Bronze while maintaining the same electrical conductivity of 15 percent IACS.

  • CuSn5 Phosphor Bronze Strip has 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.

  • C51000 Bronze Strip 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.
