Product introduction

48~50% Nickel Permalloy is a soft magnetic alloy primarily composed of approximately 48–50% nickel and 50% iron, featuring high saturation magnetic flux density and good initial permeability, making it one of the most balanced series in the Permalloy family in terms of overall performance. Our 48~50% Nickel Permalloy bars, grade 1J50, are manufactured using vacuum melting and hot forging/hot rolling processes, offered in various specifications including round bars, square bars, and flat bars, suitable for various magnetic devices and electromagnetic components.

KEY FEATURES:

• Highest saturation magnetic flux density among Permalloy alloys, Bs up to 1.5–1.6T, suitable for high flux density applications;

• Good initial permeability, μi up to 20,000–50,000;

• Low coercivity and low hysteresis loss, effectively reducing energy loss during cyclic magnetization;

• High Curie temperature, broad operating temperature range, and excellent thermal stability;

• Excellent machinability, supporting turning, milling, drilling, grinding, and other processing methods.

TYPICAL APPLICATIONS:

• Electromagnet cores and pole pieces, for electromagnets, magnetic circuit systems, and magnetic chucks;

• Relay and solenoid valve cores, for automation control, power protection, and fluid control applications;

• Magnetic shielding structural components and magnetic circuit connectors, for magnetic shielding and flux guidance structures in electronic equipment and instrumentation;

• Sensor cores and magnetic sensing elements, for position sensors, speed sensors, and other industrial sensing applications.
