REL61™ is a low-cost alternative to SAC alloys with reliability and performance characteristics equal to or greater than SAC305 and other low/no-silver solders.

REL61™ has proven to reduce the formation of tin whiskers and outperform SAC alloys in thermal shock, vibration and drop shock reliability testing. REL61™ exhibits superior spread, flow and wetting in production testing versus silver-free alloys.

REL61™ is available in bar solder, solder wire, and solder paste.
