50% tin, 50% lead - hardens faster than 60/40 solder
Good for filling in gaps, 3 dimensional work and lamps.
ONYX- 50/50 Solder. Since it has a higher melting point (melts at 413 deg F, solidifies at 361 deg F) a bit of extra care is recommended for lead came work. Testing shows that Amerway 50/50 solder has flow characteristics approaching that of 60/40 solder from other makers.
