Co-NETIC®

Overview

Co-NETIC® is considered far superior in shielding performance due to its consistent quality, material composition and Perfection Annealing process. A Ferromagnetic that is used primarily in low intensity fields where high attenuation is desired (high initial permeability & high shielding efficiency), it has become our leading brand. Co-NETIC® alloy is readily available from stock in three forms:

Co-NETIC® AA Perfection Annealed
Co-NETIC® Stress Annealed
Co-NETIC® B Stress Annealed
