Rochester, NY: Arnold Magnetic Technologies Corporation (“Arnold”), a subsidiary of Compass Diversified (NYSE: CODI) and leading global manufacturer of high-performance magnets and Precision Thin Metals, highlights its Thin Molypermalloy product offerings. With its high magnetic permeability, Molypermalloy is especially suited for RFI and EMI shielding in the Industrial market.

To construct its Molypermalloys, Arnold utilizes nickel-iron alloys and other soft magnetic materials because of their high permeability and low core losses. These soft metal characteristics make them ideal for high performance and efficient energy storage, transfer, and shielding. As with its other products, Arnold offers unique material customization to maximize permeability at customers’ target application frequency.

Arnold also offers adapted testing for Molypermalloys and other high-frequency materials to better predict material performance across applications. Arnold’s standard testing system can measure iron losses up to 20kHz in electrical steels. For applications that operate at higher frequencies, its new High Frequency Tester can provide permeability results, both real and anticipated, from 1MHz – 2.5GHz. These results will be used to inform processing conditions and tailor the material’s response to customers’ unique application needs.

The high permeability, efficiency, and adaptability of Arnold’s Molypermalloys make them an ideal fit for RFI and EMI shielding in Industrial applications. Arnold’s Thin Molypermalloy is available in a range of thicknesses, 0.01″ – 0.00031″ or 0.00030″ – 0.00008″, depending on the width.
