& Soldering Products

Soft solders are filler metals that melt and flow below 800° F. They are typically available in solid wire or cored with a rosin or acid flux. Soldering alloys are available in tin, lead, silver, copper, antimony and other compositions and can be fabricated into wire, strip, paste, powder or preformed shapes.
