Silver Brazing Wires
Available in straight wires and spooled coils with smooth oxide-free surface and superior wetting performance. Compatible with flame, high-frequency and furnace brazing for precision instruments, electronics, stainless steel, copper alloys and molds. Various cadmium-free alloys and full wire sizes, custom packaging, conforming to AWS A5.8.
Product Overview
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.
