Silver Brazing Rods are cadmium-free silver-based filler metals formulated with silver, copper, zinc, and tin, and optionally nickel for enhanced joint strength and wetting performance.
By introducing tin (Sn) into the Ag–Cu–Zn system, the alloy achieves a lower melting temperature, improved plasticity, and excellent wettability on stainless steel and copper alloys.
These rods produce bright, clean, and dense brazed joints without cadmium pollution, making them ideal for food-grade stainless steel brazing and other environmentally sensitive applications.
Low Brazing Temperature: Reduces thermal stress on base materials.
Excellent Flow and Wettability: Ensures uniform fillet formation and capillary penetration.
Cadmium-Free & Environmentally Safe: Suitable for food, medical, and sanitary applications.
High Joint Strength: Strong, ductile connections resistant to vibration and impact.
Smooth & Bright Finish: Produces clean, aesthetically superior seams.
