Ferrite Ring Magnet

Ferrite Ring Magnet is a ring-shaped permanent magnet made of ferrite material.

Composition and Characteristics: It is pressed by mixing the powder of iron oxide and other metal oxides, and then sintered at high temperature. It has high magnetic permeability and resistivity, stable magnetism, not easy to demagnetize, and low cost. However, its magnetic force is relatively weak and its texture is brittle and fragile.

Shape and size: It is in the shape of a circle with a hole in the center, with various sizes of outer diameter, inner diameter, and thickness to suit different application scenarios.

Production process: Including raw material mixing, molding, sintering, processing, and surface treatment steps. The raw materials are first mixed in a certain proportion, pressed into ring-shaped blanks, then sintered at high temperature to make it dense, then machined to achieve the required dimensional accuracy and surface quality, and finally improved through surface treatment to improve corrosion resistance, abrasion resistance, and other properties.

Application areas: in electronic equipment, such as computer monitors, televisions, cell phones, etc., used to inhibit high-frequency noise interference, to ensure the quality of signal transmission; in the power adapter, charger, and other equipment, to reduce the impact of electromagnetic interference on other electronic components; in the field of automotive electronics, such as automotive audio systems, engine control systems, etc., to help improve the stability and reliability of automotive electronic equipment; in the field of industrial automation control, it can be used as an integral part of sensors, motors and other equipment to realize the functions of position detection, speed control, etc.; in medical equipment, such as magnetic resonance imaging (MRI) equipment, it is used to generate a stable magnetic field; in daily necessities, such as magnetic door suction, magnetic hooks, etc., its suction is used to realize the corresponding functions.
