Curie temperature and temperature coefficient are for reference only, not as a basis for decision.· The maximum working temperature of magnet is changeable due  to ratio of length and diameter and environment factors. Advantage: As is typical of oxide ceramics, hard ferrite magnets display relatively resistant behavior towards moisture, solvents, alkaline solutions, weak acids, salts, lubricants and gas pollutants. Generally, hard ferrite magnets can therefore be used without additional corrosion protection. Feature: Due to their great hardness (6-7 Mohs), Ferrite magnets are brittle and sensitive to knocks or bending. During processing, they have to be machined with diamond tools.  Operating temperatures with ferrite magnets are generally between –40ºC and 250ºC. Application: Different shapes are used in utomotive engineering, such as automation and measurement control. Other applications such as Automobile electrical machinery (wipers, sit chair motor), Teaching, Door absorber, Magnetic bike and massage chair, etc.   Today, hard ferrites represent the largest proportion of permanent magnets produced.  In contrast to AlNiCo magnets, hard ferrites are characterized by flux densities but high coercive field strengths. This results in the generally flat shape of the materials. Barium ferrite and strontium ferrite are differentiated depending on the starting material. All stated values were determined using standard samples according IEC 60404-5. The following specifications serve as reference values and may differ.    The corporate upholds the philosophy of "Be No.1 in quality, be rooted on credit rating and trustworthiness for growth", will proceed to serve aged and new buyers from home and abroad whole-heatedly for Leading Manufacturer for China High Quality Microwave Oven Ferrite Magnet for Microwave Oven Magnetron, We warmly welcome pals from all walks of everyday living to cooperate with us.
