Amerway "Sapphire" 60/40 Wire Solde (1 lbs. spool)
SAPPHIRE-60/40 is 60% tin and 40% lead. A consistent and smooth flowing solder, 60/40 is the best selling alloy in the stained glass field. It melts at 372 deg F, and solidifies at 361 deg F.
The “pasty range” (most solders melt at a higher temperature than they solidify at, the difference between these figures is the pasty range) of 60/40 is smaller than that of 50/50, giving the user a smoother bead.
