Introduction of Hard Ferrite Magnet

    Ceramic (Hard ferrite) magnets were developed in the 1960’s as a low cost alternative to metallic magnets, which have strong demagnetization resistance. Because they are hard and brittle, they need special mechanical process. Due to low cost, ferrite magnets have broad application fields, ranging from motors, speakers to toys and crafts. It is the most widely used permanent magnet material. 
    Ferrite magnets are manufactured through powder metallurgy, therefore, the residual magnetism and recoil permeability are low. But because of strong coercive for and demagnetization resistance, ferrite magnets are suitable o work in magnetic circuits under dynamic working condition. The main material is oxide, so they are not easy to corrode. The working temperature is -40℃ to 250℃. 
    Ferrite ceramic magnets can be specified into isotropic and anisotropic magnets. Isotropic magnets have lower magnetic performance, but can be magnetized through different directions, while anisotropic permanent magnets have stronger property, but can only be magnetized through predetermined direction.    
       Genesis New Journey offers an array of ferrite/ceramic magnets. Ferrite (ceramic) permanent magnets are composed of strontium carbonate and iron oxide. They are charcoal gray in color and usually appear in the forms of discs, rings, blocks, cylinders, and sometimes arcs for motors.

Characteristics of Ferrite Magnet 

1. Low cost, widely used in many different applications

2. Stable magnetic property with strong demagnetization resistance

3. High coercivity (do not lose their magnetic properties easily)

4. Good corrosion resistance, no coating required for surface protection

5. Hard and brittle, could do wire cutting with diamond tools

6. Working temperature from -40℃ to 200℃

Here are some aspects of our ceramic magnets that we believe will attract merchants to our product:

1. High Temperature Resistance

One of the significant characteristics of our ceramic magnets is their exceptional resistance to high temperatures. These magnets can withstand temperatures up to 480°C, making them an ideal solution for high-temperature applications such as motors, generators, and sensors.

2. Corrosion Resistance

Our ceramic magnets are highly resistant to corrosion, making them suitable for use in harsh environments. These magnets are ideal for use in marine and underwater applications, as well as in areas with high levels of humidity or saltwater exposure.

3. Low Cost

Ceramic magnets are relatively inexpensive compared to other types of magnets like neodymium magnets. Our competitive pricing allows our customers to get high-quality magnets at cost-effective prices, making it a valuable investment for their businesses.

4. Ease of Availability

We understand the importance of timely delivery, which is why we maintain large inventories of our ceramic magnets. This enables us to fulfill orders promptly and meet the demands of our customers in a timely and efficient manner.

5. High Coercivity

The coercivity of ceramic magnets is extremely high, which means they are highly resistant to demagnetization. This property makes them an ideal choice for use in appliances and other devices that require a stationary magnetic field.

6. Customization Options

We offer our customers a wide range of customization options to help them find the right magnet for their application. This includes various shapes, sizes, and magnetic strengths, making it easier for them to find a magnet that meets their specific needs.

7. Eco-Friendly

Our ceramic magnets are made from environmentally friendly materials, making them an eco-friendly option for businesses that are committed to sustainability.
