J60, J61 & F46A Low Temperature Solder and Flux Kit

The J61 Solder contains only silver and tin. This makes it a much stronger solder although it melts easily. The unique feature of Ferree’s J61 Silver Solder is although it melts at 430°F (221°C), it doesn’t flow until 535°F (279°C). This gives a plastic range of 105°F (40.6°C) which makes it very easy to fill a hole. It is unlike other suppliers brands of solder which melt and flow freely at the same temperature. We are making this solder available in a kit, which includes 8oz (227g) or about 45ft (13.7m) of J61, 1/16” (1.6mm) O.D. and 3.5oz (103.5ml) of the special F46A flux to use with it.
