Thermal Welding PowderIt's a blended product.ItBy controlling the particle size and oxidation rate of copper oxide, adjust the heat release reaction of the flux and the temperature of the metal liquid reduced after the reaction, fully utilizing the heat release reaction to make the weldment joint a molecular structure.zuiUltimately obtainedWeldReceivedFor a copper typeWeldReceiveddotWeldingOutcomingWeldingReceivedDot is a molecular bond, non-aging, andReceivedEffects of Corrosive Products; Suitable forWeldReceivedCopper, copper alloys, copper-clad steel, copper rails, cast iron, and various alloy steels including stainless steel and high-resistance heating materials..GuaranteedWeldReceivedQuality.Soldering flux, a gray powder substance, commonly comes in specifications such as:#90, #115, 150, 200, 250, and 300 heat release welding fluxes. The number of the heat release welding flux indicates the weight in grams per bag. One bag of heat release welding flux is paired with one bag of primer and one metal separator. The primer and metal separator are prone to be lost on construction sites, as each primer kit contains a fixed number of metal separators. Therefore, proper storage is essential.
