The 1J85 Nickel-Iron Magnetic Alloy (also known as Ni80Mo5, E11c, Permalloy, 79HMA, or PCS) is a high-performance soft magnetic alloy composed of approximately 80% nickel (Ni), 15-20% iron (Fe), and small additions of molybdenum (Mo) and other trace elements.
Widely used in the radio-electronic industry, precision instruments, remote control and automatic control system.
Key Characteristics
High Permeability – Excellent magnetic response in weak magnetic fields.
Low Coercivity – Easily magnetized and demagnetized, reducing energy loss.
Near-Zero Magnetostriction – Minimizes dimensional changes under magnetization, improving stability.
Good Corrosion Resistance – Nickel content provides resistance to oxidation.
