Material Description:
Low alloy steel, silicon. A work hardenable steel alloy that offers very good magnetic properties, tensile strength, hardness, wear resistance, and increased spring steel strength. Can be plated or coated for corrosion resistance. Often used for armatures, relays, solenoids, and applications where good magnetic, low core loss and high electrical resistivity in AC and DC applications is required.
