Indalloy 291 is a direct replacement to the previously patent-protected Sn100C alloy. Indalloy 291 is commonly used in wave soldering and reworking processes as a no-silver, lead-free alternative to SAC305. Indalloy 291 is available in bar, solder paste, and solid and cored wire. Indalloy 291 bar and wire will comply with the requirements of ASTM B-32, J-STD-006 (formerly QQS-571F) and JIS-Z-3282. Each batch of solder alloy used to manufacture Indium Corporation’s bar solder, bar solder chips, and cored wire is analyzed for metallic composition and impurities. Indium Corporation will certify its bar solder and cored wire to meet customer specifications with a Certificate of Compliance or provide a Certificate of Analysis upon request.
