Bar Solder

Puretronix bar solder meets and exceeds specifications established in ASTM B32, ANSI/J-STD-006 (formerly QQS-571F), and JIS Z3282. Extruded from high purity metal under stringent quality control procedures, Puretronix bar solder is a homogenous bar exhibiting miminal oxide levels. Less dross, fewer bridges, and more reliable solder joints mean increased production efficiencies and improved return on your solder investment.

Every lot of Puretronix is shipped with either a chemical analysis or certification of compliance. The lot number and alloy are stamped into each bar. Puretronix is available in one pound and two pound bars, eight pound flat bars and plating anodes. Custom sizes are available upon request.
