Product Description

Sunraj Industries exports Phos-Copper-Silver Brazing Alloys which have good wettability, higher strength and toughness of brazing seam and lower meltingpoint. The heating speed should be as quick as possible while brazing. The joint is bright grey and will return to the original colour of bronze while dipped into 10% sulphuric Acid.

Main Features:

  • Solidus curve is lower than Cu-P brazing alloys, better wettability, strength and toughness.
  • Easy flow, good solderability and plastic nature, better strength.
  • Good strength along with increase in Ag.
