Exothermic Powder — High Performance Weld Material.
Exothermic powder is a specialized welding compound designed to generate intense heat through a controlled chemical reaction, enabling the formation of strong, permanent bonds between metal components. Widely used in exothermic welding, this powder is ideal for creating high-quality electrical connections, particularly between copper and steel conductors.
The composition typically includes copper oxide and aluminum, which, upon ignition, react exothermically to produce molten copper alloy. This molten metal flows into a weld cavity or mold, solidifying to form a robust, corrosion-resistant joint.
This makes it an essential solution for grounding systems, lightning protection, railway signaling, and other electrical infrastructure applications.
