Hard Ferrite Ceramic Block Magnets with Hole

Ferrite magnets are the cheapest in the market. Its visual appearance is of a metallic oxide of dark gray color. They have a great resistance to corrosion and therefore, they are one of the most appropriate products for different outdoor applications thanks to being stainless. They can also be exposed to temperatures of up to 250ºC. They are probably the best alternative to neodymium magnets, as they not only resist humidity and corrosion, but are also resistant to different types of chemicals.

Product Detail

Hard Ferrite Ceramic Block Magnets with Hole

Hard Ferrite ceramic magnets were developed in the 60's and today comprise 75% of world magnetic consumption. Despite their relatively low magnetic values, they are the most popular magnet on the market due to ready availability and relatively low cost.

The raw material from which ferrite magnets are produced is Strontium Ferrite powder (mainly ScO.6Fe203) which is formed in a press while subjected to an electric field. This process allows the direction of the magnetic field to be determined during the production of the magnet.

Block Ferrite Magnet with Hole

Ferrite magnets main features：

1) Low cost, high energy.

2) Good anti-corrosion performance, no surface treatment needed.

3) Excellent temperature stability.

4) provide isotropic and anisotropic.

5) Good electrical insulation, excellent demagnetization resistance

6) High coercivity, high resistance, long-term stability, economic price

7) Best choice for industrial application.

Magnetization

1.Isotropic ferrite magnets are not oriented and can be magnetized in any direction;

2.Anisotropic ferrite magnets are different, they are all oriented in the manufacturing direction, and should be magnetized in the direction of orientation.

Ferrite magnets popular uses:

The Ferrite Block Magnet could be used in a widerang of applications because of their high coercively andlow cost.They arewidely used in reed switches,loud speakers,security system audio, motors,magneticcouplings, for sensing, loudspeakers, holding-magnet systems, crafts,magnetic therapy, novelties.
