SmCo magnet is composed of Samarium, Cobalt, and a few transition metals. SmCo magnet is high performance, low temperature coefficient rare earth permanent magnets, and could keep their performance under the maximum working temperature up to 350 degree centigrade.Manufacturing Process of SmCo MagnetSamarium, 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 of SmCo MagnetGenerally, SmCo magnet must be machined using diamond-grinding techniques. Sometimes, machining operations may be performed on SmCo magnet using carbide tools, but surface finishes thus obtained may be less than optimal.The Standard tolerances for SmCo magnet are +/- 0.1mm for ground dimensions, but sticter tolerances are possible if specially required.  The shipment & Payment of SmCo MagnetPackage:33X23X26CM Standard export packageDelivery time:10-15daysPayment:T/T, Paypal and West unionShipment termAir(DHL, FEDEX,TNT) and sea shipment
