Silicon Bronze

A low lead brass alloy, Silicon Bronze has excellent corrosion resistance, high tensile strength and an appealing surface finish. It is used extensively in the chemical industry for its good corrosion and wear properties in chemical environments. Silicon Bronze is also known for its formability and weldability. The presence of silicon adds lubricity for load bearing applications.

    Typical Applications:
  • Bushings
  • Spacers in Aerospace Applications
  • Bearings
  • Sculpture
  • Valve
  • Hardware for Salt Water Environments
