About Us

In the past 75 years, Magnetic Metals has grown from a company that originally made nickel-iron transformer laminations for the U.S. military’s World War II telecommunications needs, to a major supplier of components for industries producing and using today’s most advanced electronics.  During that time, we have acquired the experience, technical expertise and production capability to make us one of the most competitive producers in our industry.
