Ferrite magnet

(1) Most commonly used magnets

• Ferrite magnets are the most widely used magnets in the world.

*At present, Japan and China produce more than 500000 tons in the world every year.

(2) The appearance is gray black, and the nature is the same as that of pottery

*Also called ceramic magnet, it is sintered magnet of oxide. In Japan, as an industrial magnet, it has been commercialized and developed continuously. The appearance is gray black, which has the same characteristics as pottery, so it is relatively easy to crack, so you should be careful when handling.

(3) Low cost, low magnetic magnet

*As iron oxide is the main raw material, it is suitable for low cost applications.

• Magnetic force is about 1/5 to 1/10 of titanium magnet.

(4) Rust prevention

※ Don't worry about rust. It can be used stably even in high humidity environments such as rain and water.

(5) Be careful when using low temperatures

*Although it has relatively stable magnetic characteristics, the temperature characteristics of Hcj (coercive force) are contrary to those of metal magnets. Hcj deteriorates at low temperatures. Therefore, when it is used at minus 30 ° C or lower, low temperature demagnetization must be careful.
