Low silver content brazing alloys

Etal’s brazing alloys are manufactured from high purity virgin metals so as to ensure the metallurgical properties of the alloys, such as melt temperature, flowability, cleanliness, and the exact working range. This ensures that the joints are welded with quality, thus prolonging the product life of the components, protecting them from deterioration for several years.

Low silver content brazing alloys

Their characteristics are as follows:

  • Used mainly for copper to copper joints.
  • Low cost due to the low, or non-existent, silver content.
  • Excellent resistance to corrosion for Heating, Ventilation, and Air Conditioning, and Refrigeration (HVAC) applications.
  • Good flow properties.
  • Excellent absorption characteristics.
  • Rigid and strong unions.


  • Tape
  • Bulk
  • Roll
  • Nitropak tubes

Nitropak: advantages

  • It is packed in a nitrogen-enriched atmosphere to avoid oxidization.
  • Improves flow rates, thus reducing the amount of solder.
  • Improves adhesion, thus obtaining better penetration (less pores = less leakage).
