Magnetic interference can affect the quality of a wide variety of systems involving sound, video, and instrumentation equipment. The high permeability of magnetic shielding alloys can significantly improve performance in such systems. In the medical community, magnetic shielding alloys are used to protect sensitive measuring equipment, such as electrocardiogram machines. In the automotive and aerospace industries, alloys are used to protect electronic controls. Magnetic shielding alloys, such as Co-NETIC®, NETIC®, MuMETAL®, HyMu 80®, and LE Alloy 49, are used to protect a host of products from interference including cell phones, home theater systems, computer display monitors, and retail credit card readers.
