This electrical solder is most commonly used in electronics. The 60/40 refers to the composition of the alloy, being 60% tin and 40% lead. This allows a lower melting point than 100% tin and will remain liquid for longer, allowing for better flow. The resin flux in the core cleans the surface of oils and contaminants, leaving virtually no residue.

This 55g solder comes on a plastic spool, however, is also available in a storage tube of 15g or 3.2mm x 500g on a larger plastic spool.
