1. Ferrite Powder

The primary material used in ferrite square shape magnets is ferrite powder, which is composed mainly of iron oxide (Fe₂O₃) mixed with barium or strontium carbonate. This combination provides the magnet with strong magnetic properties while maintaining resistance to corrosion and heat. The ferrite powder is finely ground to ensure uniformity, which is essential for achieving consistent magnetic performance in the final product.

2. Binding Agents

During the manufacturing process, binding agents are often added to the ferrite powder to help shape the magnet into its square form. These agents assist in holding the powder together before it undergoes high-temperature sintering. While they do not contribute to the magnetic properties, they are important for maintaining the structural integrity of the magnet and ensuring it retains its shape after the production process.

3. Protective Coatings (Optional)

Many ferrite square magnets are also finished with protective coatings such as epoxy or nickel plating. These coatings help prevent surface chipping, improve durability, and enhance resistance to environmental factors such as moisture or dust. While ferrite itself is naturally corrosion-resistant, these coatings add an extra layer of protection and make the magnets suitable for a wider range of applications.

Ferrites are suitable for various applications, such as converters and filters, microwave ovens, and other high-frequency equipment. Ferrite Fans provide a cost-effective way to remove interfering noise from sensitive electronics, while still offering better than 75dB of suppression across a wide range of frequencies. The CSR Series is an excellent choice for a compact, low-profile solution when space is at a premium.
