The difference between plastic magnetic component manufacturers and plastic magnetic particle manufacturers is more:

First, plastic magnetic mold manufacturer appearance level

Ferrite magnetic field: ferrite is soft and dull, generally not electroplating process, generally gray black.

Samarium cobalt magnets: Metallic and relatively dense.

Second, magnetic level.

Ferrite: According to the survey data, the magnetic force of ferrite is generally 500-1700 Gaussian function.

Samarium cobalt magnets: Under bare magnetic standards, cobalt magnets can have a magnetic force of around 2000 Gauss.

Third, characteristic level.

Ferrite magnetic field: ferrite temperature resistance and reliability are very good, compared with ndfeb magnet, the general temperature resistance is only 80 degrees. And the price is very cheap.

Samarium cobalt magnets: Samarium cobalt magnets are small, light and magnetic in a way that ferrites are not.

Fourth, the cost problem.

Ferrite: iron oxide price is low, many are all by the piece, the price with the appearance of ferrite design, specifications, production and processing difficulties, etc.

Samarium cobalt magnets: today, the price of samarium cobalt magnets is relatively stable, and the fact that you need to use the model and special requirements related.

Five, advantages and disadvantages.

Ferrite advantage: ferrite is characterized by high permeability, low price, high temperature resistance, suitable for low frequency sites!

Defects of ferrite: not very good magnetism.

Advantages of samarium cobalt magnet: strong magnetism, high cost performance, heat resistance, wide use, corrosion resistance, strong oxidation resistance.

Defects of samarium cobalt magnets: fragile, easily destroyed.
