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 or half pound valued pack. 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.●【General Applications】Perfect working for MAPP, MAP, propane and oxygen acetylene gas welding torch set-up. Also suitable for contact TIG welding, high frequency brazing and furnace brazing. It is an ideal choice for both professionals and DIYers.●【Better with Flux】 Bluefire JFB-102 or JFB-102S brazing flux is recommended when braze non-brass or bronze metal parts. The high quality flux will increase the brazing fluids flowablity and improve the welding joint mechanics and strength. Check our store for the recommended flux.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. Works for Aluminum and Zinc based metals welding projects. Great for repairs on irrigation pipes, carburetor bowls, aluminum boats, camper covers, lawn mower housings and casings. Bluefire JFB-102S Flux is recommended to braze non-bronze metals.
