Product Details

Thermal Spray Wire is a highly versatile product, widely used in arc and flange flame spray systems. It is especially valued for its superior corrosion resistance and high-temperature endurance. This wire is designed to create coatings that protect against heat, prevent scaling on conventional low alloy steels, and improve adhesion for top coatings. Thermal Spray Wire is also commonly used in the glass industry for mold coatings and as a bond coat to enhance the adhesion of subsequent layers.
The thermal spray wire series includes a variety of alloys, such as Inconel 625, Ni95Al5, Monel 400, Monel K500, Hastelloy C276 , and Cr20Ni80. Among these, Monel 400 Wire stands out for its exceptional resistance to corrosion and high temperatures, making it ideal for bonding layers and other protective coatings.
