|Article number:||SPCU Copper Paste Solder|
This solder flows at 1,325°F (roughly the same as an easy silver solder). Paste solder is ideal for saving time on the fluxing step in small jobs; it is ideal for the repetitive tasks of production soldering, such as closing jump rings, attaching ear posts and similar tasks.
Sold individually; each syringe contains 1/2 oz. of paste solder.
