Our company has more than 10 years experience to produce the silver tungsten alloy. Our products answer to the standard of GB/T8320-2003 and ASTM B631. Our tungsten silver equivalents to 2088, 20S, 30S, 35S, 50S, 4050, 20SB, 35SB, 2110, 2150.

silver tungstenHOSOPM®1 silver tungsten application:

  • circuit breakers
  • earth leakage breakers
  • miniature circuit breakers
  • resistance welding electrode
  • wear resistance shaft

 HOSOPM®1 series tungsten silver advantage:

  • High conductivity, high hardness
  • high heat conductivity
  • wear resistance, resistance to the burning of the arc

HOSO METAL use the advanced vacuum infiltration process to produce tungsten silver alloy, which is also called PSI process. so our silver tungsten product has very high density and electrical conductivity. silver tungsten product catalogue (PDF, 350K).

Tungsten silver adopts these process routes:  mix powder preparation –pressing – sintering – infiltration -machining.tungsten silver process
