Soft magnetic alloys are a class of alloys with low coercivity and high permeability under weak magnetic field, which is an important metal functional material. Under the condition of no external magnetic field applied, the soft magnetic alloy itself does not show magnetic properties, under the action of external magnetic field, the soft magnetic alloy is gradually magnetized, showing stable magnetic conductivity characteristics, when the soft magnetic alloy is separated from the external magnetic field, the magnetic properties disappear. Because of their special magnetic properties, soft magnetic alloys have a wide range of applications in communication, electric power, new energy and other industries.
As one of the precision alloy and supply providers, Beiye has mastered the high-precision and high-flatness control technology of soft magnetic alloy strip/wire/foil, and solved the problems of dimensional accuracy and plate shape control of strip/wire/foil. Through systematic research, the comprehensive quality of soft magnetic alloy products has been significantly improved, the production capacity has been increased, and the industrialization of multi-species, multi-specification and multi-purpose soft magnetic alloys has been realized.
Soft magnetic materials, characterized by high magnetic permeability, low coercivity, and easy magnetization/demagnetization, are used in various applications due to their ability to efficiently conduct magnetic flux. Here are the primary uses:
Transformers: Soft magnetic materials, like silicon steel, are used in transformer cores to enhance magnetic coupling, minimize energy losses, and efficiently transfer electrical energy between circuits. Soft magnetic alloys, such as silicon steel and amorphous alloys, offer low hysteresis losses, making them ideal for high-efficiency transformers.
Electric Motors and Generators: These materials form the cores of stators and rotors, enabling efficient magnetic field generation and energy conversion with minimal hysteresis losses. Soft magnetic alloys like silicon steel and nickel-iron alloys (e.g., Permalloy) reduce eddy current losses, enhancing motor efficiency.
Inductors and Chokes: Used in inductors for energy storage and filtering in power electronics, soft magnetic materials like ferrites reduce core losses at high frequencies. Soft magnetic alloys, such as iron-silicon-aluminum (Sendust), provide high saturation magnetization for compact designs.
Electromagnetic Shielding: Soft magnetic materials, such as mu-metal, shield sensitive electronics from stray magnetic fields by redirecting flux. High-nickel soft magnetic alloys like Mu-metal offer exceptional permeability for effective shielding.
Magnetic Sensors: Employed in Hall-effect sensors and magnetic field detectors, these materials leverage high magnetic sensitivity for automotive and industrial applications. Soft magnetic alloys like Permalloy enhance sensor precision due to their rapid magnetic response.
Solenoids and Relays: Used in electromagnetic actuators and relays to create controlled magnetic fields for switching. Soft magnetic alloys, such as iron-nickel alloys, ensure low residual magnetism for reliable operation.
Magnetic Recording: Soft magnetic materials in read/write heads of hard disk drives enable precise magnetic field manipulation for data storage. Soft magnetic alloys like iron-cobalt alloys support high-density data recording.
Power Supplies and Converters: Found in switch-mode power supplies and DC-DC converters, these materials reduce energy losses in high-frequency components. Amorphous soft magnetic alloys minimize core losses for improved efficiency.
Microwave Devices: Ferrites, a type of soft magnetic material, are used in microwave components like circulators due to their high-frequency performance. Soft magnetic alloys like nickel-zinc ferrites maintain stable magnetic properties in these applications.
Medical Devices: Used in MRI machines to create strong, controlled magnetic fields with minimal energy loss. Soft magnetic alloys, such as iron-nickel alloys, enhance field stability for high-quality imaging.
