Y30BH Arc Ceramic Magnet Overview
Ferrite arc magnets, also known as ceramic magnets, were developed in the 1960s as a cost-effective alternative to metallic magnets. These magnets offer excellent corrosion resistance and good resistance to demagnetization, making them widely used in various industrial applications.
Key Characteristics
- Very hard and brittle material - not suitable for structural applications
- Good corrosion resistance typically requires no coating
- Fairly strong magnetic power (Power-Index = 4~5)
- Cost-effective solution (Cost-Index = 1~3)
- Available in both isotropic and anisotropic versions
- Manufactured through powder metallurgical engineering
- Excellent temperature stability and corrosion resistance
- Service temperature range between rare earth and alnico magnets
