Puralloy® Grade K 60/40 is a leaded solder alloy incorporating lead and tin, with a melting range of between 183-190°C. Grade K is a High Purity Leaded Alloy (60Sn /40Pb) manufactured from a grade of solder alloy with purity levels meeting all the requirements of both national and international standards. Grade K is widely used across a range of Electronics & industrial processes, as it is ideal for all soldering applications involving brass and copper components due to the excellent flow, good wetting characteristics, provision of a strong joint and a bright finish to your solder joint. Grade K is a lower cost alternative to Grade A (63/37). Suitable liquid fluxes would be Bakers Soldering Fluid and TSC 920 for both brass and copper.
