Copper Phosphorus Alloys

  • The Copper-Phosphorus alloys are extensively used to join copper and copper alloy base metals (brass, bronzes).
  • They have self-fluxing properties when used on copper and may or may not contain Silver.
  • A flux is required when joining brass or bronze.
  • Continuous service operating temperatures of joints brazed with these alloy range up to approx 200°C.

 Copper Phosphorus Alloys

Brazing and braze-welding fluxes

  • Flux AG4
  • Activity Range °C: 550 - 850
  • Standard: EN1045

Silver Brazing Alloys Cadmium Free

  • General purpose brazing alloys, suitable to join easily a wide range of ferrous and non-ferrous base materials (iron, steel, stainless steel, copper, brass, etc.).
  • Continuous service operating temperatures of joints brazed with these alloys range up to approx 200 °C.
  • When joining stainless steel in wet environments, in order to avoid failure of the joint due to interfacial corrosion, it is recommended to use zinc-free alloys (Ag60Sn/1), or alloys with Nickel additions.
