Description: Ceramic magnets or ferrite magnets are sintered permanent magnets composed of barium or strontium carbonate, and iron oxide. This class of magnets, aside from good resistance to demagnetization, has the popular advantage of low cost. The sorts of hard ferrite magnets are manifold and complete. They are charcoal gray in color and usually appear in the forms of toroid, circular disk, square, bar, arc segment, blocks, rings, cylinders special magnets etc. The detail specifications are up to hundreds of kinds. The corrosion resistance of Ferrite is considered excellent and no surface treatments are required. It can be used in temperatures up to 80 degrees C. However, Ceramic magnets may have a thin film of fine magnet powder on the surface and for clean, non-contaminated applications, some form of coating may be required. Standard parts include blocks, discs, rings & round bars in different dimensional specifications. Magnets are available in different shapes & sizes and can also be custom fabricated according to specifications & tolerances. Ferrite magnets are very hard and brittle, and require specialized machining techniques. Moreover, they should be machined in an unmagnetized state. We are equipped to machine these materials to specifications. Anisotropic grades are oriented in the manufacturing direction, and must be magnetized in the direction of orientation. Isotropic grades are not oriented and can be magnetized in any direction, although some degree of greater magnetic strength will be found in the pressing dimension, usually the shortest dimension. 【PREMIUM QUALITY】 - Large Round Magnets Ring Strong Pack of 2, Practical size - OD: 2.36", ID: 1.26“, Thickness: 0.39“, Cermic 8 Grade! ready to be used circle magnets for all your needs. Our Selected Ceramic circular magnetic rings are Stronger than other Ceramic Donut Magnets.Ceramic 8 Grade are Stronger than Ceramic 5 grade. 【BEST CHOICE FOR CRAFT】 - Large Ring Permanent magnets for discretionary design. These ring ferrites are similar in magnetism to neodymium rare earth magnets and cheaper than neodymium rare earth magnets.These ring magnets have industrial strength and are great for home, office, school, crafts, science projects. 【STRENGTH & DURABILITY 】- Ferrite Round Magnets have High resistance to demagnetization, corrosion and oxidation. Our Bing ring magnets are the strongest magnetism to satisfy your various needs and applications. The power exists forever under 200°Temperature. 【MULTI-PURPOSE】- People widely use Our Strong Round Magnets Ring as Kitchen magnets, Office magnets, Speaker Magnets, Science magnets, Classroom magnets, Refrigerator magnets, Industrial magnets, Fridge magnets, Craft magnets, DIY magnets and Hobby magnets. 【USING WARNING 】 - The large magnets heavy duty is very fragile, it is forbidden to collide with other metal objects (including another magnet), Strong Magnetic Ring force will make round magnets with hole attract each other. so be careful when you are trying separte them !
