China Rare Earth Magnet Limited is one of the leading samarium cobalt magnets manufacturers in China. We can provide a full range of samarium cobalt magnets at quite reasonable and competitive price and we have the ability of manufacturing different grades of samarium cobalt magnets as well, ranging from SmCo18 to SmCo30H. Normally, we customize or OEM samarium cobalt magnets according to our customers' requirements. The shapes of samarium cobalt magnets that we can manufacture include block, disc, ring, segment, arc, counter bore and other irregular shapes.
Samarium cobalt magnets, which belong to the rare earth magnet family, have been available since the early 1970's. There are both sintered samarium cobalt magnets and bonded samarium cobalt magnets, but most customers require only sintered samarium cobalt magnets. Sintered samarium cobalt magnets are anisotropic and can only be magnetized in the direction of orientation. Samarium cobalt magnets possess very high magnetic properties, excellent thermal stability, and remarkable resistance to corrosion and oxidation. All these characteristics make samarium cobalt magnets very ideal for applications used in high temperature working environment.
Samarium cobalt magnets are the second generation of rare earth permanent magnets. The main characteristics of samarium cobalt magnets are high magnetic properties and high working temperature. The maximum working temperature of samarium cobalt magnets can be up to 350°C. As a result, samarium magnets are more suitable for working in high temperature environments than neodymium magnets and alnico magnets. Besides, samarium cobalt magnets have remarkable resistibility against corrosion, so generally their surface does not require electroplating processing.
Samarium cobalt magnets are widely used in computer disc drives, sensors, satellite systems, motors (whose temperature stability is vital), aeronautic and space industries, etc. We, China Rare Earth Permanent Magnet Co., are a professional China samarium cobalt magnets manufacturer and our products have been sold worldwide. Our main market is developed countries, such as USA and Western European countries. If you want to purchase samarium magnets directly from China samarium cobalt magnets manufacturers, I believe, our company is a very good choice for you.
Can samarium cobalt magnets be used to protect motors by absorbing iron filings in the oil used in motors? There is someone saying that sticking a circle of samarium cobalt magnets to the outside of oil filters can absorb iron filings, thus the iron filings in the oil can be prevented from circulating. But also some people doubt about this kind of notion; they thought most parts of motors does not use iron materials now, then where do the iron filings come from? What's your idea about this topic? You can e-mail us your answers if you want to share your opinions with others. |
