NON-FERROUS METALS

PHOSPOR BRONZE

Phospor Bronze

Phosphor bronze alloy is obtained by adding a small percentage of phosphorus, about 0.03-0.035% by weight, to give bronze alloys unique properties such as improved flow, wear resistance and hardness. Their densities are around 8.8 g/cm³. This means that most forms of alloys respond to hot working, cold working and heat treatment. They are highly elastic by nature, resistant to fatigue and corrosion. They can also be easily shaped, cast and soldered. The addition of lead makes phosphor bronzes stronger and more workable. But lead-free phosphor bronzes are also strong and resistant on their own. They are often used in corrosion resistant applications as well as other applications that need a springy yet durable material.

Phosphor bronze has been used in electrical components for many years. However, thanks to technological developments and the demand for more special materials, new areas of use are still being discovered.
 
Areas of common use:
 
  • Springs
  • Bushes and bearings
  • Welding rods
  • Guitar Strings
  • Dental bridges
