For over 60 years, The MuShield Company Inc. has been an industry leader in the fabrication of custom magnetic shielding for the Medical, Defense, Aerospace, Biochemical and Aviation Industries. Using a high permeability alloy commonly known as HyMu 80 or MuMetal to shield sensitive electronic equipment, we are able to solve all of your Electro Magnetic Interference (EMI) problems. When the Smithsonian Astrophysical Observatory scientists set up an experiment to test Einstein's Theory of Relativity, they specified MuShield to protect the atomic clock used to explore the structure of space and time. With state of the art machinery, we are also able to work with other sheet metals such as Aluminum, Brass, Copper, Hastelloy, Low Carbon Steel, Stainless Steel and Tantalum, while holding the tightest of tolerances. Our customers come to us with all of their high precision sheet metal needs and we give them the high quality product they deserve!
