Permanent Alloy Magnets Free Sample Samarium cobalt magnets (also known as SmCo magnets), are extremely powerful permanent magnets. Part of the rare-earth magnet family, SmCo magnets rank similarly in strength to neodymium magnets but have much higher temperature stability and higher coercivity. They can operate at temperatures up to 525掳F (300掳C). In addition, they have a very high resistance to demagnetization and to corrosion. SmCo magnets are available in numerous shapes, sizes and grades that span a wide range of properties and application requirements.Among all shapes of SmCo magnets, SmCo arc magnet is one of the most popular products in our company. Sizes & Shapes - Standard samarium cobalt magnet shapes include discs, blocks, rings, and arc segments in a variety of sizes and grades. Non-standard shapes can also be custom fabricated to blueprint specifications from raw stock. We can custom manufacture samarium cobalt magnets in virtually any shape and size to meet your project鈥檚 exact requirements. Temperature Considerations - SmCo arc magnets exhibit magnetic properties that are very stable with temperature, and can be used in applications where temperatures reach up to 572掳F (300掳C). They perform well for applications where the stability of magnetic characteristics is critical. Manufacturing Methods - SmCo arc magnets are extremely brittle, so they are prone to chipping and cracking. Therefore, special machining techniques involving diamond-grinding must be used to machine this material prior to magnetization. We are fully equipped to machine these materials to your project鈥檚 specialty requirements. Surface Treatments - The corrosion resistance of Samarium Cobalt is very good, therefore coatings to protect SmCo arc magnet from corrosion or oxidation are generally not required. Magnetizing & Assembly Considerations - SmCo arc magnets are anisotropic, and can only be magnetized in the orientation direction. Magnetizing fields in excess of 50 KOe are required to saturate these materials. Handling & Storage - SmCo arc magnets are extremely brittle, but magnetically very strong. Therefore, special care must be taken when handling these to avoid injury to personnel and damage to the magnets.Permanent Alloy Magnets Free Sample website:http://www.yanhemagnet.com/permanent-alloy-magnets/
