Magnetic Shield

Founded in 1941 as the Perfection Mica Company, we originally focused on mining and processing of Mica in a North Carolina mine, and subsequently gained ownership of the Buster mine located in the Dakotas, the largest Mica mine in the world during the 1940s. Concurrently, the Magnetic Shield Division was founded to develop materials and processes to control magnetic fields for NASA space travel. Shortly after developing the Magnetic Shield Division, it grew to such a dominant position in our business that the company changed its name to Magnetic Shield Corporation. The developments and industrial awareness of Perfection Mica Company in the television & electronics industry led to an easy transition. Driving the strategy and continual growth was sensitive electronic applications that were developed during WWII. By the mid-1950s, magnetic shields were found in high demand and overtook the Mica business, and Magnetic Shield Corporation officially became the primary enterprise in 1956. Sincethen, Magnetic Shield Corporation has been a primary leader in the industry, registering our proprietary brands of shielding alloys Co-NETIC(R) and NETIC(R) in 1955, and INTER-8(R) weaved cable soon after. These products became the benchmark in magnetic shielding alloys. Since the 1960s, other companies have attempted to evolve in the shielding market; many of them created by former employees of Magnetic Shield Corporation. However, to this day, Magnetic Shield Corporation holds a reputable position built around decades of experience and product developments. One well known brand that stands out worldwide is MuMETAL(R), which is legally a proprietary brand of Magnetic Shield Corporation.
