Silver Brazing Filler Metal
Silver-based brazing filler metals are alloys primarily composed of silver or silver-copper. They exhibit excellent processing characteristics, including relatively low melting points, good wettability and gap-filling capabilities, as well as outstanding strength, plasticity, electrical conductivity, and corrosion resistance. As a result, they are one of the most widely used categories among hard brazing materials.
Various Shapes & Customizable
Various forms including brazing rods, rings, wires, sheets, strips, paste and powder are offered, and all dimensions can be customized as your requirements.
| Rods | Φ1.5-4.0mm | Length:15-1000mm |
| Flat Rods | 0.05" x 1/8" | Length:450-500mm |
