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.
