Nasco Resincore Solder 250g – 2mm, 40/60 Tin/Lead

Nasco Resincore Solder is a 250g spool of 2mm diameter solder with a 40/60 tin-to-lead ratio, featuring a triple-core flux design for reliable electrical and general soldering work. The non-corrosive, non-conductive flux core ensures excellent wetting properties and even distribution across joints, making it ideal for copper bit soldering on circuit boards, electrical connections, and general maintenance applications. This solder is manufactured from virgin base metals and natural resins, suitable for work that does not require lead-free compliance.
