  • Development and Sales of Coated Cermet Grade "T2500Z" for Steel Turning

Sumitomo Electric Industries, Ltd. (Head office: Chuo-ku, Osaka, President: Osamu Inoue, hereinafter referred to as "our company") has developed and launched the Coated Cermet Grade "T2500Z" for Steel Turning. Longer tool life has been achieved by improving stability in steel turning such as rolled steel, carbon steel and alloy steel.

Cermets, with titanium compound as the main component, have low affinity with iron, providing a glossy and beautiful machined surface on ferrous metals. Cermets have also been attracting attention in recent years for using only a small amount of tungsten, which is a scarce resource.
Our company has developed a new cermet substrate with excellent thermal conductivity in pursuit of a "glossy, beautiful and stable surface finish" that is particularly required for cermets, and has launched the Coated Cermet Grade "T2500Z" combined with "Brilliant Coat®" that significantly reduces reactivity with ferrous metals.

1. Features

Excellent machined surface quality

The newly developed cermet substrate with excellent thermal conductivity, improves thermal crack and notch wear resistance. In addition, our company's original coating technology "Brilliant Coat®" is used to achieve excellent wear and adhesion resistance, providing stable and excellent machined surface quality in various work materials such as rolled steel, carbon steel and alloy steel.

Excellent lubricity and wear resistance

"Brilliant Coat®" has excellent lubricity and significantly reduces reactions with ferrous metals. As a result, adhesion of the work material is greatly reduced which prevents tearing, and the wear resistance required for coated grades has been improved by over 1.5 times as compared to our company's conventional products. Not only providing beautiful finished surfaces but also a longer tool life in the finishing process.
