Hard Ferrite Magnets
Hard Ferrite magnets are a cost-effective and widely used type of permanent magnet, known for their durability, resistance to corrosion, and stable magnetic performance. While they offer lower magnetic strength compared to rare-earth magnets, their affordability and reliability make them ideal for high-volume applications and rugged environments.
These magnets are commonly paired with reed switches in sensor systems, where consistent magnetic fields are required for activation. Their performance remains stable under moderate temperature and field conditions, making them a dependable choice for many industrial and consumer applications.
- Cost-Effective: Lowest cost among all permanent magnet types.
- High Electrical Insulation: Suitable for applications requiring isolation.
- Good Demagnetization Resistance: Maintains magnetism even in strong external fields.
- Corrosion Resistant: Performs well in liquid environments.
- Temperature Tolerance: Operates up to 250°C.
- Brittle and Ceramic-Like: Requires grinding for shaping; low tensile strength.
- Consumer Electronics: Speakers, motors, and magnetic holders.
- Automotive: Sensors, actuators, and fuel system components.
- Industrial Equipment: Magnetic separators, pumps, and float systems.
- HVAC Systems: Magnetic components in fans and compressors.
- Security & Safety: Magnetic locks and sensors.
- Medical Devices: Non-critical components requiring corrosion resistance.
