Safety-Silv® 40

Silver-copper-zinc filler metal with a melting range that is useful where part clearance cannot be tightly controlled for brazing copper, brass and steel.


Safety-Silv 40 is a ductile, free-flowing, alloy that is economical, provides good penetration into tight connections at a medium temperature. It is silver-to-light yellow in color making it a good match to polished brass.


  • Cadmium-free, silver brazing alloy
  • Good ductility
  • Often used for corrosion applications or high temperature service, so suitability for the brazing alloy should be evaluated for the intended condition
  • Good replacement for hazardous cadmium bearing filler metals
  • Moderate temperature alloy with a medium plastic range, making it suitable for brazing assemblies with wider gaps
  • Corrosion resistance is generally similar to copper base metal, but because of its zinc content it should Not be used if the braze is exposed to concentrated corrosive liquid for long periods of time
  • Conforms to the EU Reach & RoHS directive

Typical Applications

  • Brass brazing
