Magnets Ceramic Sheet
Ceramic magnets do not need to be protected for surface rust. They require special machining techniques, and should be machined in an un-magnetized state.
Ceramic Magnets are extremely powerful and brittle, requiring appropriate handling and packing to guarantee safety and avoid damage. They are manufactured using powder technology techniques. They are very resistant to corrosion. As with all magnet alloys, they should not be used as structural elements.
You may never go wrong with our massive range of ceramic magnets. Due to the properties of ceramic magnets, a lot of the machining needs to be achieved with diamond tooling. The mold has to be made in two pieces so the original model can be eliminated and so that the mold can be full of clay and unmolded.
Magnetic ceramics are widely used in human daily life, science and technology and national defense. Fumigation is a kind of magnetic ceramic material made of ferric oxide and ferromagnetic oxide without iron element. Magnetic ceramics, also known as ferrite or ferromagnetic oxygen, are important types of special ceramic materials.
Magnetic semiconductor ceramic material, its resistivity in 10 ~ 107 Ω m., used as the core, the vortex loss is small, low dielectric loss, the most suitable for use in the general magnetic metal magnetic material is not up to the high frequency, the variety of magnetism performance, make the magnetic ceramics in automation control, electronic computer and microwave technology is widely used, their shows its strong vitality.
According to the crystal structure, magnetic ceramics are classified into spinel type, garnet type and magnetic lead type. According to different external magnetic field and magnetization, it is divided into five categories: soft magnetic ferrite, pressure magnetic ferrite, rotating magnetic ferrite, large magnetic ferrite and pressure magnetic ferrite.
Soft magnetic ferrite is easy to be magnetized and demagnetized. It is suitable for repeated magnetization. Its biggest use is a variety of transformers, sensors, electromagnets, relays and other inductor components.
Hard magnetic ferrite, with strong magnetic hysteresis, is not easy to demagnetize after magnetization, and can keep its magnetism for a long time. The permanent magnetic field is generated mainly as permanent magnet in magnetic circuit. For example, it is used as recording head, TV focusing device and loudspeaker, oscilloscope, magnetoelectric meter and so on.
Rotating magnetic ferrite has the effect of rotating magnetic field, which can cause the electromagnetic wave to deflect at certain Angle. By using this property, various kinds of metamaterials can be made, such as attenuators, modulators and circulators, isolators, phase reversers, as well as frequency doubler, mixer, amplifier, etc.
Moment magnetic ferrite, magnetic material with rectangular hysteresis loop, can be used in memory components, logic components, magneto-optical memory and magneto-acoustic memory on electronic computers, etc.
Magnetostrictive ferrite material, which can produce magnetostrictive effect under external force. A material that produces magnetostrictive effects under external forces. It can be used in ultrasonic engineering. Ultrasonic generator, receiver, sound detector and sonar, etc. Make all kinds of memory in the calculation; A filter in the direction of telecommunications, a frequency stabilizer oscillator, etc.
