Description
63/37 NO CLEAN Solder Wire The main constituents of 63/37 solder wire are Tin (Sn) and Lead (Pb). This Solder wire is made of the high purity of white rosin and proprietary activators which provides rapid wetting and good spreadability. KTE wire is made from virgin Tin/Lead having 99.9% purity. Health and Safety: It is not toxic however a certain amount of fumes will be generated, therefore these fumes must be exhausted for the operator’s safety.
