1J50 Soft Magnetic Alloy Pipes for Magnetic Shielding and Inductors
1J50 Soft Magnetic Alloy Product Overview
1J50 is a high-performance nickel-iron soft magnetic alloy, predominantly composed of 49.0–51.0% nickel and the balance iron, with trace amounts of manganese, silicon, copper, carbon, phosphorus, and sulfur. This alloy is renowned for its exceptional magnetic properties, including high initial and maximum permeability, low coercivity, and high saturation magnetic induction. These characteristics make it ideal for applications requiring efficient magnetic performance in medium magnetic fields.
The alloy exhibits a Curie point of approximately 500°C, ensuring stable magnetic properties under varying thermal conditions. Its low electrical resistivity (0.45 μΩ·m) and high density (8.2 g/cm³) contribute to its suitability in applications where magnetic efficiency and structural integrity are paramount. Additionally, 1J50 demonstrates excellent machinability and formability, allowing for precise fabrication into various shapes and sizes, including pipes, rods, wires, and strips.
1J50 pipes are extensively used in the manufacturing of magnetic cores for transformers, relays, electromagnetic clutches, chokes, and magnetic shielding components. Their ability to operate effectively in medium magnetic fields makes them indispensable in industries such as electronics, aerospace, power generation, and petrochemicals.
