Product Details
1J85 is a premium nickel-iron-molybdenum soft magnetic alloy
renowned for its exceptional magnetic properties and reliable
performance in precision applications. With a nickel content of
approximately 80-81.5%, molybdenum at 5-6%, and a balanced
composition of iron and trace elements, this alloy stands out for
its high initial permeability (over 30 mH/m) and maximum
permeability (exceeding 115 mH/m), making it highly sensitive to
weak magnetic signals. Its extremely low coercivity (less than 2.4
A/m) ensures minimal hysteresis loss, ideal for high-frequency
alternating magnetic fields.
Beyond its magnetic strengths, 1J85 boasts impressive mechanical
properties, including a tensile strength of ≥560 MPa and a hardness
of ≤205 Hv, enabling easy cold working into wires, strips, and
other precise forms. With a Curie temperature of 410°C, it
maintains stable magnetic performance even in elevated
temperatures, while its density of 8.75 g/cm³ and resistivity of
around 55 μΩ·cm further enhance its suitability for demanding
environments.
Widely utilized in miniature current transformers, residual current
devices, high-frequency inductors, and precision magnetic heads,
1J85 remains a top choice for engineers seeking a blend of
sensitivity, durability, and versatility in soft magnetic
materials.
