Silver-Based Cadmium-Free Filler Metals

These alloys are low-temperature, free-flowing filler metals for joining similar and dissimilar metals (i.e. copper to steel). They produce very strong, ductile joints and are safe because they are cadmium-free. Lucas-Milhaupt offers numerous material compositions for general purpose and specialty applications. The Braze family of alloys is available in strip, wire, powder, paste, preforms as well as clad tri-metal products and flux-cored wire.
