Silicon Bronze (AMS 4616)C65620 CW009A  CuSi3Fe2Sn3 


C65620 Silicon Bronze Rods (AMS 4616) is an engineering alloy resistant to corrosion as copper itself, but much stronger, and with good fatigue endurance. The alloy is appreciated for its brazing ability, strength, corrosion resistance and electrical properties and serves as one of the most weldable copper alloys. The alloy can be joined by using resistance welding, soldering or brazing. The alloy is joined by gas shield arc welding, spot welding and also by oxyacetylene welding.

Typical Applications:

  • Electrical: Sculptures,Electrical,Pole Line Hardware,Motors,Rotor Bar
  • Fasteners: Screws,Rivets,Burrs,Nuts,Nails,Cotter Pins,Clamps,Bolts,Hinges
  • Industrial: Screen Cloth,Wear Plates,Screen Plates,Shafting,Wire,Welded Pressure Vessels,Oil Refinery Plumbing Tube,Bearing Plates,Butts
  • Marine:  Vessel Hardware ,Propeller Shaft
