Product Details

Thermal spray wire is widely used in arc and flange flame spray systems, offering exceptional resistance to corrosion and high temperatures. This makes it an ideal material for coatings that help to resist heat and prevent scaling of conventional low-alloy steels. Thermal spray wire is also used as bond coats to improve the adhesion of top coatings, especially in applications like coatings on molds in the glass industry.
Thermal spray wire comes in various alloys, including Inconel 625, 45CT, Ni95Al5, Monel 400, Monel K500, Hastelloy C276 , and Cr20Ni80. These materials provide robust solutions for industrial applications, ensuring superior performance even in the harshest conditions.
