Malaysia, 11 November 2026 – Mitsui Kinzoku Company, Limited has approved a ¥190 billion investment, equivalent to about RM4.87 billion at the reported exchange rate, to build a copper foil factory in Malaysia. The Japanese materials group’s board approved the project on 10 November. The plant will be built near its existing Malaysian subsidiary, Mitsui Copper Foil (Malaysia) Sdn Bhd, and is scheduled to start operating in stages from April 2031.

The project expands Malaysia’s role in supplying specialised materials for artificial intelligence infrastructure and semiconductors. Mitsui Kinzoku is investing in two types of foil used in advanced electronics, rather than simply adding general-purpose metal capacity. The decision confirms a capital commitment and a planned schedule; it does not mean the additional foil is available now or that the company has secured orders for the entire expansion.
