Exothermic welding (fire mud welding, hot melt welding)
The main purpose of copper oxide sheet is exothermic welding.
Exothermic welding (fire clay welding, hot melt welding) is to produce liquid high temperature copper liquid and alumina residue through the chemical reaction (exothermic reaction) of aluminum and copper oxide, and use the high temperature generated by the exothermic reaction to achieve high performance Modern welding process for electric welding.
3CuO+2Al======(heating) 3Cu+Al2O3
This reaction is carried out in a high-temperature graphite mold, and the exothermic reaction process takes only a few seconds to complete.

Copper oxide is an inorganic substance, chemical formula CuO, is a black oxide of copper, slightly amphoteric and slightly hygroscopic. Insoluble in water and ethanol, easily soluble in acid, stable to heat, decomposes oxygen at high temperature. Copper oxide is mainly used for making rayon, ceramics, glazes and enamels, batteries, petroleum desulfurizers, pesticides, and also for hydrogen production, catalysts, green glass, etc.
