Carbon Brushes, Carbon Commutators, Assemblies, Powder Metallurgy

TRIS USA’s carbon brushes are a global brand and used in cars all over the world. We have a large share of the automotive carbon brush market and recognized as a world-leading brand.
TRIS USA uses a uniquely formulated carbon material that is corrosion resistant in its commutator plates , and is also used in various fuel pumps, (including gasoline and diesel), that require high voltage and high loads.
TRIS USA has been supplying products for more than half a century as a pioneer in powder metallurgy in Japan and Worldwide!

Estimated lifespan of 1 million km with TPM!

As an important part of EESM, our high-performance carbon brushes for winding fields contribute greatly to the high performance, long service life, and maintenance-free of motors.
We are also focusing on the development of compact brush holder assemblies, and by making product lighter and more compact, we will contribute to improving the electrical consumption of EESM EVs and downsizing motors.

TES prevents electrical corrosion and removes noise!

With the required performance improvement requirements of inverters and motors in electric vehicles (EVs), the problems of electric corrosion and radiated noise have come to the forefront. TRIS USA has developed and adopted high-performance earthing brushes for radiation noise suppression since the first generation all electric Nissan LEAF, and is developing a high-performance earthing system that can be used in a variety of environments and applications, such as electrolytic corrosion in oil, and for small brushless motors.

Contributing to carbon neutrality with the TSM Series!

Using TRIS USA’s proprietary special processing technology, we have developed TSM, a high-performance, multifunctional material that achieves high dimensional stability and low torque. As the first step, it is adopted as a replacement for bearings for water pumps, contributing to the improvement of pump performance.
