History

Starting as an incandescent light bulb filament maker in 1933, we have expanded our market and applications as an entrusted development-oriented component manufacturer. From Tungsten to Molybdenum, Tantalum to Niobium, Platinum and Iridium, there are a vast amount of materials in which Mitsuwa Micro Technologies handles. These are not only procured from Japan, but imported from countries throughout the world such as the Americas, China, and India. As we respond to various developmental needs, our business partners extend beyond the US, to over 20 countries in Europe and Asia.
