Soldering Alloys

Soft solders are filler metals that melt and flow below 840°F (450°C) and are used for low temperature applications. 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. When you purchase Lucas-Milhaupt’s soldering alloy products, not only do you get the most premium product on the market, you get 65 years’ worth of Lucas Milhaupt technical expertise at your fingertips and access to our regional team managers to work with you and your team.
