Product Details

Thermal Spray Wire is a vital material for arc and flame spray systems, offering superior anti-corrosion and high-temperature resistance. It is widely used for coating applications where heat resistance and wear protection are crucial. These coatings are ideal for low alloy steels, protecting them from heat-induced damage and scaling. Thermal spray wire is also used as a bond coat to improve adhesion for top coatings, particularly in industries like glass manufacturing and electronics.
