Ring Ferrite Magnets

Ferrite disc magnets are a type of permanent magnet made from ferrite, a ceramic material that consists primarily of iron oxide and other metal oxides, such as strontium carbonate. These magnets are characterized by their high resistance to demagnetization, making them suitable for various applications.

Composition and Properties
- Material Composition: Ferrite magnets typically contain about 90% iron oxide and 10% strontium carbonate or barium carbonate. This composition contributes to their low production costs and makes them economically viable for mass production.
- Physical Characteristics: Ferrite disc magnets are usually dark gray or black and exhibit good strength relative to their size. They are also known for their corrosion resistance, eliminating the need for protective coatings.

Types of Ferrite Magnets
Ferrite magnets can be categorized into two main types based on their magnetic properties:

- Hard Ferrites: These have high coercivity, meaning they maintain their magnetization and are used in applications like loudspeakers, refrigerator magnets, and small electric motors.

- Soft Ferrites: With lower coercivity, these are easily magnetized and demagnetized, making them ideal for use in high-frequency inductors and transformers.

Features Low cost, high-energy, good electric insulation and excellent resistance to demagnetization High coercive force, high electric resistance, long-time stability, and econ.

Permanent

Q: What are the plated layers on the surface of the iron boron?

Answer: Magnetic surfaces can generally be used as gold-plated, tin, chromium, nickel, zinc, phosphorus, epoxy resin, and other anti-corrosive treatments.

Q: How to separate the magnets together?

Answer: Methods and precautions for separating magnets:

1) Staff must bring labor and protective gloves to protect hand safety.

2) Clear iron items, watches, mobile phones, magnetic cards, etc. around magnets around magnets.

3) The magnet should be placed on the wooden table (the magnet that is not adsorbed by the magnet), reserving a space for high and low differences.

4) Fix the magnet on the edge of the table, press the magnets that are separated from the pre-separated magnet, and force it down.

5) Do not relax the power before the magnet is separated by 0.5 meters, and keep it to avoid the magnet re-sucking.

For strong magnets with large sizes, customers may find it difficult to separate. Our company has dedicated tools to separate. Customers can send it back to our company. We handle it and send it to the customer. The round-trip freight requires the customer's burden.
