Sintered ferrite magnetic ring can not only ordinary charge magnetic (axial radial 1 pair of pole charged magnetic), but also multipole magnetic magnetic, that is, a plane or side multiple poles, we call it multipole magnetic ring, because this product is a sintering process, so also called sintering ferrite multipole magnetic ring.

Sintered ferrites (also known as ceramic magnets) were developed and produced in the 1950's;

Sintered ferrite magnets mainly include barium ferrite (BaO•6Fe2O3) and strontium ferrite (SrO•6Fe2O3); sintered ferrite is divided into isotropic magnets and anisotropic magnets.

Performance: The magnetic properties of isotropic sintered ferrite are weak, and have the same magnetic properties in any direction.

Multi-pole magnetization in any direction; Anisotropic sintered ferrite magnets have higher magnetic properties than isotropic ones,

It can only be magnetized in the orientation direction of the magnetic field during molding; the main raw material of sintered ferrite is oxide,

Therefore, it will not be corroded by high temperature, high humidity or chemical substances (except strong acid and alkali).

Application field: Because the raw materials are cheap and the production process is relatively simple, the cost is low,

Therefore, sintered ferrite is by far the most widely used permanent magnet material;

It is widely used in permanent magnet motors, DC motors, speakers, reed switches, magnetic separators and adsorption devices, etc.

Others: sintered ferrite has excellent demagnetization resistance, no magnetic flux loss before and after assembly and magnetization;

The working temperature of sintered ferrite is -40°C to +250°C, and the temperature coefficient is poor;

The temperature coefficient of Br is -0.2%/°C, that is, for every 1°C increase in temperature, Br decreases by 0.2%;

Sintered ferrite has high hardness and can be processed by wire cutting and grinding;

Sintered ferrite is brittle and fragile, so it should be handled with care during production and transportation.

FAQ

Q:What is the difference between the product performance of the different materials？

A：The common performance of general car starters is MGC 36h, MGC 37h series; the common performance of air conditioners and refrigerators is MGC 35b, MGC 36b series; the common performance of electric tools and ceiling fans is MGC 33, MGC35 series (MGC is our company's magnetic tile grade)

Q:How long is the regular production delivery period after the formal mass production？

A：Generally 25 days, delivered by order delivery.

Q：What if there is no conforming mold for the first product？

A：If there is no conforming mold, a new mold needs to be opened first. The production cycle of the new mold is 20-25 days. The product production can be carried out after the mold production is completed and verified.

Q：Is there any requirement for the product order quantity？

A：Generally there is a minimum starting quantity, a single batch of value in about 10,000-20,000.
