YOM Exothermic Welding Powder is a powdered weld metal, comprised of copper and aluminium. Exothermic weld is a effortless, profitable and durable welding connection that adopt a high-temperature exothermic reaction to invent a molecular bond. The reaction reaches temperatures over 1500°C thus achieving the fusion of the materials to be welded. Material can be permanently joined within seconds. The conductors are joined by the resulting product of the main reaction when it gets to the solid state. Exothermic Welding does not corrode oxide or degrade with time and is resistant to galvanic coupling. Exothermic Welding offers a permanent welding and a low resistance connection, essential for achieving longwearing and trustworthy results in earthings. Exothermic Welding has an excellent corrosion resistance.
