Strength through innovation

With more than 30 years of experience in manufacturing, TOKUSEN U.S.A., Inc. is the originator of shaped wire for automotive piston rings, and we supply 70% of the market as it shifts from using cast wire to steel wire. Our roots are in Japan where “tokusen” means “specialty” wire, and today, our US manufacturing operation translates complicated customer needs and turns them into reality through collaboration, innovation, and environmentally sustainable operations.

We custom manufacture nano silver flakes through a unique milling process which makes them flat and superior to the competition with lower sintering temperatures, improved packing density, and increased electrical connectivity.

And 100% of our steel fibers for Ultra High-Performance Concrete (UHPC) are Made in the USA using high carbon steel rod from a US-based mill, turning it into fibers conforming to ASTM A820 as requested for US Federal government projects.
