Ferrite Magnet
Introduction
Ferrite Magnets, also known as ceramic magnets or hard ferrites, are produced through calcining a mixture of iron oxide (Fe2O3) and barium carbonate (BaCO3) and then sintering for consolidation.
Because of the low cost and excellent corrosion resistance of its raw material, the ferrite magnet gains an advantage in price and the environmental tolerance and has become one of the most widely used permanent magnets.
Features
• High magnetic permeability, excelling in environments requiring strong magnetic fields
• Lower cost, offering economic advantages
• Good temperature stability
• Corrosion-resistant, ensuring stable application
• Easy to process, meeting design requirements
• Requires mold fabrication; after molding, mass production is feasible
工作溫度
-40～250°C
Applications
• Motors for automotive interiors
• Starter motors
• Electric seat motors
• Windshield wipers
• Household appliances
• Air conditioners
• Washing machines
• Fans
