Phosphor Bronze UNS C52100 Forgings
C52100, B103
Phosphor bronze UNS C52100 alloys were of great significance in the Bronze Age. The addition of phosphor in bronze alloys increase wear resistance, fatigue resistance and hardness, thus allowing the usage of the phosphor bronze alloys in shafts, fasteners, valve spindles, masonry fixings, bearings, springs and gears.
Bronze copper alloys are available in different forms and some of them include:
- Phosphor bronze
- Tin bronze
- Aluminium/Aluminum bronze
- Silicon bronze
- Architectural bronze
- Manganese bronze
UNS C52100 phosphor bronze copper alloy has good spring qualities, ductility and strength. The following datasheet provides an overview of UNS C52100 alloy.
