Bronze Casting Alloy: Silicon Bronze C873

With a pleasant color and ability to accept a range of patinas, combined with a good fluidity, low drossing, and reasonable solidification range, Silicon Bronze (C873) is widely used for industrial applications. Silicon Bronze, meeting high military standards such as ASTM B584 (formerly ASTM B198-12A), has good brazing, welding, and a machinability of 40, allowing balanced mechanical properties and quality corrosion resistance.

Choosing Silicon Bronze C87300 for Your Bronze Alloy Castings

C873 has excellent casting characteristics, such as an easy pouring ability and appealing surface finish, which have resulted in its being a preferred bronze within the aerospace, marine, and industrial markets. In defense applications, silicon bronze has typically been used to produce weapons and weapon components. Particular alloys, such as C873, are typically found in:

  • Pumps
  • Valves
  • Industrial casting requiring corrosion resistance
  • Bearings
  • Bells
  • Impellers
  • Pump and valve components
  • Marine fittings
  • Corrosion-resistant castings

Silicon Bronze C873’s characteristics give it an edge over other metals and metal alloys, making it a versatile metal alloy for numerous industrial applications. The strength and self-lubricity it offers is especially useful when it comes to producing bearing cages, raceways, and spacers for the aerospace industry.
