Sintered Smco Disc Magnet 

SmCo magnets, are composed of Samarium, Cobalt, and a few transition metals SmCo magnets are high performance, low temperature coefficient rare earth permanent magnets, and could keep their performance under the maximum working temperature 350 degree centigrade. Manufacturing Process Samarium, Cobalt, and a few transition metals will be made into the SmCo powder, then fine SmCo powder will be compacted in a die and sintered, fusing the powder into a solid material. There are 2 forms of pressing: die pressing and isostatic pressing. Sintered parts normally need some finish machining in order to meet final tolerances. Machining & Tolerance Generally, SmCo magnets must be machined using diamond-grinding techniques. Sometimes, machining operations may be performed on SmCo materials using Carbide Tools, but surface finishes thus obtained may be less than optimal. The Standard tolerances for SmCo magnets are +/- 0.1mm for ground dimensions, but s…
