About Magnetic Shield Corporation

"Theory Is One Thing, Practicality Is Another, Evaluation Is Everything"

Usually, theory raises more questions, and provides no finite answer to technical professionals. That's why Magnetic Shield Corporation's engineering team has developed practical methods of evaluating performance. Global businesses, engineers, scientists, inventors, and educators in over 80 countries have used our Evaluation Lab Kits and proprietary shielding materials for hands-on evaluation. As a leading expert since 1941, Magnetic Shield Corporation has developed thousands of technical solutions, supplied millions of fabricated shields, and refined our proprietary shielding materials to be the most effective alloys available. For further explanation how theory may be applied to your application, how to evaluate your design, or how Magnetic Shield Corporation's production capabilities and technical solutions can help, view our complete Company Brochure.

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. Since then, Magnetic Shield Corporation has been a primary leader in the industry, registering our proprietary brands of shielding alloys Co-NETIC® and NETIC® in 1955, and INTER-8® 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®, which is legally a proprietary brand of Magnetic Shield Corporation. If you need MuMETAL®, contact Magnetic Shield Corporation, the sole USA supplier.
