FAQ
Q1: What are the main materials of ferrite magnets? What are the advantages compared with NdFeB magnets?
A1:Ferrite magnets are made of iron oxide and barium/strontium carbonate sintered together, and are ceramic permanent magnets. Compared with NdFeB magnets (rare earth magnets), their core advantages include:
Lower cost: no rare earth elements are required, suitable for large-scale applications;
Stronger high temperature resistance: conventional temperature resistance reaches 150°C, and customized models can reach 230°C (NdFeB is usually ≤80°C);
Excellent corrosion resistance: moisture-proof, acid-resistant and alkali-resistant without electroplating, suitable for harsh environments;
High stability: small magnetic attenuation under high temperature or long-term use, and longer life.
Q2: What are the common performance levels of ferrite magnets? How to choose the appropriate level?
A2:Common performance levels include Y10T, Y25, Y30, Y30BH, and Y35, corresponding to different magnetic energy products (BHmax):
Y10T/Y25: low magnetic energy product, suitable for small appliances, toys, and simple adsorption scenarios;
Y30/Y35: high magnetic energy product, used in motors, industrial equipment, audio and other high-performance demand fields;
When choosing, it is necessary to combine the magnetic strength, temperature environment and cost budget of the application scenario. For example, Y30BH (high temperature stability optimization) can be selected for high temperature scenarios.
Q3: Can ferrite magnets be customized with special shapes or magnetization directions?
A3:Supports high customization:
Shape: In addition to the standard round shape, we can produce thousands of specifications such as square, ring, countersunk hole magnets, special-shaped cutting parts, etc.;
Magnetization direction: The default thickness direction magnetization, axial (along the center of the circle) or radial (along the edge tangent) magnetization can also be customized to meet complex magnetic field requirements;
Surface treatment: optional nickel plating (anti-corrosion), epoxy plating (insulation), gold plating (decoration), etc., to adapt to different environments.
