The table below summarizes most alloys commonly used is soldering applications. For additional information on commercially available alloys please visit EFD Soldering Group.
Furthermore should you choose to send in your sample parts for complimentary evaluation offered by LEISTER, we will help you identify the soldering alloy that suits your application the best. Equally so, if you have a preferred alloy, LEISTER will gladly use it to solder your sample parts and give our feedback and recommendations.
