Feature●【Value Pack】 Each tube contains 9 pcs of bare solid bronze brazing alloy rods, each rod measures 1/8" in diameter and 14" in length. Total 1/2 lb valued pack plus JFB-102S Silver Brazing Flux powder.Great saving!●【Optimized Formula】0.01-0.4% Phorsphor, 7-9% Sn Tin, Rest for Copper. Low Fume substitite for the classic brass brazing alloys, LFB (bare low fuming bronze) is excellent for building up wearing surfaces or large areas where successive layers must be added; galvanized parts can be brazed without damaging the zinc coating. Solidus Temperature: 1607°F / 875°C, Liquidus Temperature: 1877°F / 1025°C. Tensile strength：37700 PSI;●【All Purpose】Widely used for joining various ferrous and non-ferrous metals such as carbon steel, copper alloys, cast iron, malleable iron, stainless steel and some nickel alloys. Perfectly Brazing for all copper and brass parts,such as water heater, radiant heater, cleaner,etc.Also perfect working for MAPP, MAP, propane and oxygen acetylene gas welding torch set-up. Suitable for contact TIG welding, high frequency brazing and furnace brazing.●【Used with Flux】The silver brazing flux powder is used with silver-bearing alloys jointing copper-copper, steel-stainless steel and dissimilar metals. Active Range 600-850℃ Completely dry powder, contains more contents than the water-mixed flux paste. Increase the welding performance for the silver copper brazing alloy, enhance the fluidability and wetability of the brazing fluid.●【Functions of Flux】The important functions of soldering flux are as follows: assisting heat conduction, clearing the oxide on the surface of parent materials and brazing materials. reducing the surface tension of soldered materials, clearing oil stain on the surface of Soldered materials (parent materials), enlargino brazing area, avaidingre-oxidation etr It ran he divided into solid paste, liquid and gas .Description BLUEFIRE JCUSN is a low fume brazing alloy substitute for the brass brazing rods, Copper combined with Phosphor and Tin, is a low fume (LFB), easy flow and simple to use brazing alloy for both professionals and DIYers. It has a melting point of about 890-1025°C. The bronze alloy is suitable to braze low carbon steel, cast iron, nickel alloys and hard alloy parts, the joint has higher intensity and better plasticity. So, for manually hand welding thin wall steel or iron parts, brass alloy is the best choice. And The important functions of soldering flux are as follows: assisting heat conduction, clearing the oxide on the surface of parent materials and brazing materials. reducing the surface tension of soldered materials, clearing oil stain on the surface of Soldered materials (parent materials), enlargino brazing area, avaidingre-oxidation etr It ran he divided into solid paste, liquid and gas .
