Composition and characteristics

 

Main ingredients: SrO or BaO and Fe₂O₃ are usually the main raw materials 127.

 

Characteristics: It has high magnetic permeability and resistivity, stable magnetism, not easy to demagnetize, and low cost, but its magnetic force is relatively weak and its texture is brittle and fragile.

 

Application field

 

Electronic equipment field: In audio equipment such as speakers and headphones, it is used to generate magnetic fields and drive the voice coil to vibrate and make sounds; in hard disk drives, it is used to control the read and write position of the magnetic head.

 

Automobile field: It is used in the electric power steering system, electric seat adjustment system, car audio system, etc. of automobiles to provide magnetic fields for various motors and sensors.

 

Home appliance field: For example, the magnetic material used in refrigerator door seals is usually ferrite disc magnets, which can provide enough suction to keep the refrigerator door tightly closed; it is also used in the motors of home appliances such as washing machines and air conditioners.

 

Industrial field: In motors, generators, magnetic separators, sensors, and other equipment, it is used to generate magnetic fields or realize magnetic induction functions.

 

Medical device field: In some small medical devices, such as blood glucose meters and blood pressure meters, it is used to achieve certain specific functions, such as sensor triggering or data transmission.

 

Toys and crafts field: Because of its low cost and certain magnetic properties, it is often used to make various toys and crafts, such as magnetic puzzles, magnetic ornaments, etc.
