Our packaging contains 40 pieces of Phos copper brazed alloy rods, each rod is 2mm in diameter 5/64 inches and 25cm in length / 9.85 inches.Total 1/2 pound or half pound or 250 grams of package.Use our products to meet all your needs Our Phos copper brazing rods comply with A5.8.Chemical composition of brazing rod: phosphorus (P): 6.6~7.4%, copper (copper): residual.Low measurement point 710-820℃.Solid temperature: 1310°F / 710°C, liquid temperature: 1508°F / 820°C.Good fluidity during welding, molten metal can flow into small gaps Phos copper brazing alloy has air self-permeability, moderate melting point and high fluidity, and performs perfectly under gas flame, induction, furnace brazing and other methods; has higher joint strength and stronger conductivity; is very suitable for the setting of MAPP, MAP, propane and oxyacetylene gas welding flashlights.Also suitable for contact TIG welding for professionals and DIY enthusiasts BCuP-2 is suitable for resistive brazing, flame brazing and high frequency brazing.Copper-phosphorus brazing alloy is suitable for brazing of copper and copper alloys, and is widely used in refrigerators, household appliances, motors, instruments and other manufacturing industries. The phosphorus in the brazing alloy is used as a soldering agent, so when using copper-phosphorus copper brazing alloy, there is no need to use a solder.
