Proterial, Ltd, a Tokyo-based global materials manufacturer, will establish a production site for the amorphous metal material Metglas™ in India. Amid growing global demand for electric power, demand for Metglas™—which enables higher efficiency in transformers when used as a core material— is expected to increase significantly. To meet this demand, the company will address the world’s energy-saving needs by establishing a three-site structure encompassing the United States, Japan, and now India.

Proterial recognized the energy-saving potential of amorphous metal materials early on and began research and development efforts in the late 1970s. In 2003, Hitachi Metals, Ltd (now Proterial) acquired the amorphous metal materials division Metglas, Inc (South Carolina, USA) from Honeywell International, Inc in the United States and formally launched its amorphous metal materials business. In 2007, mass production commenced at Yasugi Works (Yasugi, Shimane Prefecture, now Metglas Yasugi Works), establishing a two-site manufacturing and sales structure split between the US and Japan. In March 2020, now Proterial developed a new amorphous alloy, MaDC-A®, which contributes to further improving the efficiency of transformers, as part of the Metglas™ lineup. Proterial is now a leading company in the field of amorphous metal materials, handling everything from research and development to mass production.

In recent years, electricity demand has increased significantly due to economic growth in emerging nations, rapid growth in the number of data centers, and the ongoing progress of electrification. This growth is expected to continue. India, in particular, is expected to experience rapid growth in electric power demand due to its population increase and ongoing economic development centered primarily on the IT industry and manufacturing. When used as a core material in transformers, Metglas™ can reduce standby power usage by approximately one-third—based on Proterial’s estimates using transformer standard JIS C 4304:2024—compared to using electromagnetic steel sheets as the core material, enabling higher transformer efficiency.

Consequently, within India, alongside active investment in power infrastructure, a sharp increase in demand for Metglas™ is anticipated, as an amorphous metal material essential for achieving higher transformer efficiency. Proterial currently produces Metglas™ for the Indian market at Metglas Yasugi Works and exports it. Anticipating future global growth in demand, including the Indian market, it has decided to establish a new production site in India (Sri City, Tirupati District, Andhra Pradesh) to expand production capacity as part of the Proterial Group. The new base will primarily serve domestic demand in India. With this new manufacturing site, Proterial will address the world’s energy-saving needs by establishing a three-base structure encompassing the United States, Japan, and now India.
