our history

Bringing solutions since 1929

The two predecessor companies, Shibaura Engineering Works Co., Ltd. and Tokyo Electric Company, succeeded in developing cemented carbide for the first time in Japan. The product was sold on the market as “Tungaloy”.

Building up on a successful past for the bright future

Since its inception in 1929 when it was Japan’s first company to develop cemented carbide, Tungaloy has had a long history of excellence in the development of materials for metal cutting tools and innovative industrial products.

The diverse range of products, including metal cutting tools, such as indexable inserts and steel products, wear resistant tools, civil engineering tools, and friction materials, are all based upon Tungaloy’s expertise in powder metallurgy.
