Tungaloy Corporation (株式会社タンガロイ, Kabushiki Kaisha Tungaroi) is a company that specializes in production and sales of metal cutting tools as well as industrial products. Headquartered in Iwaki, Fukushima, Japan, it was the first company in the country to succeed in developing superhard alloy.

August 2008 marked a turning point for the company, as Tungaloy became a member of the International Metalworking Companies (IMC), owned by Warren Buffett’s Berkshire Hathaway. This acquisition led to rapid installation of latest machinery and automation in its production facilities as well as advanced its R&D laboratories. In 2010, Tungaloy’s headquarters, marketing, production, and R&D functions gathered in Iwaki, Fukushima in Japan to streamline communication channels and improve synergy between the departments. The company celebrated the opening of its new production plant in 2011 with the presence of Warren Buffett, which turned into his first visit to Japan.
