Specification Brand : BlueFire BulletPoint : Requires only that you dip the piece into Magic Boric and solder – the flux is built right in. No burn-off or waiting to solder. It prevents fire scale and will cut your soldering time by as much as 50%. Non-flammable and non-hazardous. BulletPoint1 : 【A Must Have】Active content: CESIUM FLUOROALUMINATE (complex), which greatly improved the solderability and enhance the fluidability and wetability of the brazing fluid, allowing the brazing fluid can penetrate into the depth of the welding gaps instead of floating on the surface, assure a strong and solid brazing joint. Acive Range:824-1166℉ (440-630℃). For any user who want to brazing large diameter pipes or wroking on shallower gaps and deeper penetrate depth, this is a Must-Have. BulletPoint2 : 【Versatile】Bluefire J9802 Aluminum brazing alloy, commonly known as Low Temperature or All Purpose aluminum brazing alloy, is one of the most widely used. Works on aluminum, aluminum alloy, die-cast, bronze, nickel, titanium, zinc, copper, brass and most non-ferrous (non-magnetic) metals (does not work with steel except for galvanized steel). Meet all your needs for most welding and repairing projects. Whether you're a professional or an amateur, this brazing flux will be your choice. BulletPoint3 : 【Easy to use】We are honest seller, if you just want to do some filling jobs, this flux is not necessory. However, if you want need to fill the shallow and deep gaps or weld objects with special shapes, Bluefire JSC-FLUX brazing flux can effectively increase the penetration depth of the soldering liquid and form a stronger and solid joint. No need for complicate skills, just polish and clean, dip the rods into the flux, and then brazing, IT IS THIS EASY! BulletPoint4 : 【Containing Rare Earth Elements】The product contains cesium element. Cesium is less abundant in the earth's crust, it is one of the rare earth elements and has an expensive value. BulletPoint5 : 【Quality Assurance】All Bluefire brazing flux is manufactured under the highest quality control. CE certificated, 7/24 customer support availabel.
