Ferrite magnets or ceramic magnets are widely used in speakers, toys, DC motors, magnetic lifters, sensors, microwaves and industrial magnetic separators and handling systems, due to good resistance to demagnetization and the lowest cost among all kinds of permanent magnets.
1. Highly resistant to corrosion. Normally coating is not required to protect ferrite magnets from corrosion, but for other purposes, for example epoxy coating applied to ensure ceramic permanent magnets clean and dust-free.
2. Excellent thermal performance. If the product requires a magnet that needs tolerating high operating temperatures up to 300 °C, while maintaining magnetic force, please choose to consider ferrite permanent magnets as an option.
3. Highly resistant to demagnetization.
4. Stable and affordable price. Ferrite magnets are perfect for mass production, entirely according to the customer’s requirements. The raw material for this magnet alloy is easy to obtain and inexpensive.
Hard and brittle. It makes Ferrite magnets less suitable for direct application in mechanical construction, because of high risk that they will break and splinter under mechanical load.
1. Ferrite magnet is produced in the magnetic assemblies.
2. Ferrite magnet is combined with a flexible plastic.
Definitely we are not a Ferrite magnet manufacturer, but we have magnetic knowledge about types of permanent magnets including Ferrite. Moreover, we can supply one-stop source for rare earth magnets, and magnetic assemblies, which can reduce customers’ energy in dealing with many suppliers to buy several kinds of magnet products at good price.
