This sample is a ferrite ceramic disc magnet, the diameter is 110mm, the thickness is 20mm, black surface color, not coated, is generally choose thickness magnetization and less than 1000Gs, Mainly used in machinery and equipment, industry, experiment, etc.
The measurement of 110 x 20mm ferrite disk magnet:
The heavy duty ferrite disc magnet is usually chose by many customer:
First, the ferrite material is cheaper than neodymium or samarium cobalt.
Secondly, If the magnet is thickness magnetization, the surface force of a disc magnet will be more uniform than that of a ring with a hole, because the hole will have less area to force.
Finally, ferrite magnet has high coercivity and strong demagnetization resistance. It is especially suitable for magnetic circuit structure in dynamic working conditions, and it is resistant to corrosion and high temperature (up to 200 ℃).
The size of diameter or thickness is not be only, we can customize all size for customer if you have any requirment. Please take your inquiry and contact us!
