Strong magnet is generally aluminum-iron boron structure, the normal magnet according to what you mean should be an ordinary

ferrite material. Rare earth NdFeB magnets (commonly known as: strong magnets, electroplated magnets, magnets) is a unique

rare metal doping some other synthetic materials made of sintered metal, known as magnet type in the magnet king;

Features: The strongest magnetic force, high performance, can be electroplated, (the most commonly used only zinc ZN, nickel-plated

NI; But also some special requirements, such as gold-plated, silver, plated, such as color, according to demand we can electroplating)

shipping fast, convenient transportation, widely used in the market is now the most common kind of magnet;

Mainly used for printing and packaging, electronics, electrical appliances, mining equipment, electrical and other fields;

Ferrite:

Its main raw material is ferric oxide. It is a kind of brittle material. It has good temperature resistance, low price and moderate performance.

It is also the permanent magnet widely used in the market at present.

Features: low price, high temperature, not easy to oxidation, magnetic difference, transport problems, slow product shipments;
Performance: the same sex Y10 Y20 Y25 heterosexual Y30;
Heterosexual than homosexual magnetic better, hardness should be strong; the opposite sex can also be used to strengthen the Y30BH;
So because of the different materials and structures, which led to the role of the two is not the same.

Aluminum-iron-boron magnetic field of a single suction than the ferrite about 30 to 50 times (the same specifications under the premise),

the combination of magnetic iron-boron inside the magnetic field strength is higher.

Please note: Ferrite magnet installation is very convenient, but the installation of aluminum-iron boron combination of magnetic system,

to the professional installation of the installation, or may lead to personal injury.
