Products Features
Extremely high magnetic saturation density and permeability
The core advantage of Hiperco® 50 lies in the inherent magnetic properties of its iron-cobalt matrix. The addition of cobalt significantly increases the alloy's Curie temperature (approximately 980°C) and magnetic saturation density, allowing it to maintain excellent magnetic performance even at magnetic flux densities as high as 2.4T, far exceeding that of silicon steel (approximately 2.0T) and nickel-iron alloys (approximately 1.6T). At moderate magnetic field strengths, it exhibits outstanding permeability, enabling higher power density in smaller volumes and weights. This makes it an ideal material for miniaturization and lightweighting of motors and electromagnets.
Excellent high-temperature magnetic performance stability
Hiperco® 50's high Curie temperature (approximately 980°C) enables it to maintain good magnetic properties at temperatures up to 400°C, with a much lower attenuation rate of magnetic saturation density compared to ordinary soft magnetic materials. It exhibits outstanding retention of permeability and magnetic flux density in high-temperature environments, making it suitable for applications such as aerospace engine accessories, high-temperature sensors, and oil drilling equipment that require tolerance to high temperatures and stringent magnetic property requirements.
Low hysteresis loss and good AC magnetic properties
Thanks to its high purity and optimized control of crystalline texture, Hiperco® 50 has low coercivity (typical value < 160 A/m) and significantly lower hysteresis loss compared to conventional silicon steel. In medium- and high-frequency AC magnetic fields, it exhibits excellent core loss performance, making it suitable for applications with strict requirements on efficiency and temperature rise, such as aviation power supplies (400Hz), radar systems, and high-speed motors.
Excellent Machining and Forming Properties
Hiperco® 50 exhibits good hot and cold working properties, enabling forging, rolling, and stamping. Its ductility surpasses that of most brittle soft ferrite magnetic materials, making it suitable for manufacturing complex laminated cores, magnetic shields, and precision stamped parts. Annealing optimizes magnetic properties by relieving processing stresses, restoring permeability, and reducing coercivity. Conventional machining (turning, milling, drilling, grinding) is applicable; carbide tools are recommended.

Antioxidant Performance:
Hiperco® 50 exhibits good antioxidant properties within normal operating temperature ranges, forming a dense oxide layer on its surface. For long-term exposure at high temperatures (>500°C), surface coating protection is recommended.
Organizational Stability:
By optimizing heat treatment, the grain structure of Hiperco® 50 can be precisely controlled to ensure consistency in magnetic and mechanical properties. Annealing temperature and time directly affect the final magnetic properties and must be strictly controlled.
Applicable Media:
