EFK, a new braze paste for joining carbon-steel parts, is paired with copper filler metals and dispensed through automatic applicators and handheld squeeze bottles. The paste is for brazing carbon-steel parts in exothermic and endothermic-controlled atmosphere furnaces. Characteristics include no hot or cold slump, it will not spatter, and leaves minimal residue under a broad range of part cleanliness and atmosphere conditions. The paste will adhere to part surfaces even after application and drying for 2 to 4 hr.
