Product Description
Low Price Customized High Performance Round Disc Ferrite Magnet
Ferrite magnet or ceramic magnet is the cheapest magnetic material available with the lowest cost/energy ratio, also known as Ceramic Magnets, they are mainly Strontium based (SrFe2O3), manufactured with Strontium Carbonate additive to increase performances from the obsolete Barium based (BaFe2O3).
Their good coercive force results from high crystal anisotropy of Strontium iron oxide. However, isotropic parts can also be produced where a simple and easy multi-pole magnetization is required. The most common shapes are simple, such as blocks,cylinders, rings and arcs. Ferrite is not conductive and has high resistance against corrosion, acids, salts, lubricants.

Magnetization Direction
A Magnetic field is an invisible flux moving from one end of the magnet to the other. Shown in Figure1. The flux consists of moving or spinning electrically charged particles invisible to the eye. If the max working temperature meet the requirement ,permanent magnets can retain the magnetic field for very long time even forever. Magnets have potential energy which means that they have the ability to conserve energy. The magnet will display or release some of its conserved energy when pulling towards or attaching to something then conserve or store the energy that the user exerts when pulling it off.
Every magnet has a north seeking and a south seeking face on opposite ends. The north face of one magnet will always be attracted towards the south face of another magnet.
Application Fields
Ferrite (Ceramic) magnets are the lowest cost hard magnets available today, it is a ceramic material made by mixing and firing large proportions of iron oxide (Fe2O3, rust) blended with small proportions of one or more additional metallic elements, such as barium, manganese, nickel, and zinc.They are both electrically non-conductive, meaning that they are insulators, and ferrimagnetic, meaning they can easily be magnetized or attracted to a magnet. Ferrites can be divided into two families based on their resistance to being demagnetized (magnetic coercivity).
Ferrite compounds are extremely low cost, being made of mostly rusted iron (iron oxide), and have excellent corrosion resistance.
They are very stable and difficult to demagnetize, and can be made with both high and low coercive forces.
· Common Applications: lifting applications, school projects, loudspeakers, guitar pick-ups, eddy current devices, breaks and clamps, motors, generators, switches, relays, security systems, sweeper magnets, crafts and model making, DIY projects, science experiments, classroom displays, store displays, lifting machinery, apparel, office display boards, home or office organization,promotional gifts and more.

Frequently Asked Questions
1. Q: Are you trading company or manufacturer ?
A: We are a professiona manufacturer of Samarium Cobalt SmCo Magnet for Motor
- Standard NdFeB magnets (e.g., N35, N38) are generally suitable for temperatures up to 80°C to 100°C.
- High-temperature grades (e.g., N35M, N38H) can operate at higher temperatures, with some grades like N35AH or N38UH capable of withstanding temperatures up to 200°C.
2. Q: How long is your delivery time?
A: Generally it is 5-10 days if the goods are in stock. or it is 30 days if the goods are not in stock, it is according to quantity.
- Select the right grade: Choose a magnet grade suitable for your operating temperature and environment.
- Avoid high temperatures: Keep the magnets within their specified temperature range to prevent thermal demagnetization.
- Shielding: Use magnetic shielding materials to protect the magnets from strong external magnetic fields.
- Proper handling: Handle the magnets carefully to avoid mechanical stress, which can cause micro-cracks and affect magnetic performance.
- Storage: Store magnets in a cool, dry place, away from strong magnetic fields and corrosive environments.
3. Q: Do you provide samples ?
A: Yes, Samarium Cobalt SmCo Magnet samples should be necessary before batch order
- Coating: Apply protective coatings such as nickel plating, zinc plating, or epoxy coating to protect the magnet from moisture and corrosive environments.
- Environment control: Store and use the magnets in dry environments to minimize exposure to humidity.
- Sealing: For applications in highly corrosive environments, consider sealing the magnets with additional protective layers or using corrosion-resistant materials in the surrounding structure.
- Standard NdFeB magnets (e.g., N35, N38) are generally suitable for temperatures up to 80°C to 100°C.
