Silver solder 30% flux coated 1.50mm (1kg)

30% flux-coated silver solder rods integrate brazing flux into the rod coating, simplifying the brazing process by eliminating separately applied flux. Suitable for joining copper, brass, bronze, steel, and stainless steel in plumbing, refrigeration, and HVAC applications. The integral flux activates on heating to clean joint surfaces and promote filler flow. Compatible with oxy-acetylene and air-acetylene torches. Supplied as 1kg pack.
