Samarium cobalt magnet and the comparison of ndfeb magnet

by:Newland     2020-05-05
Samarium cobalt magnet ( 2:17) With the comparison of ndfeb magnet: ( 1) Ingredients: ndfeb magnets, rare earth metal neodymium - 29% 32. Iron 63 5% metal elements. 95 - 68. Non-metallic element boron 1 65%. 1 - 1. A small amount of dysprosium adding 0 2%. 6 - 1. Niobium 0 2%. 3 - 0. Aluminum 0 5%. 3 - 0. 0 5% copper. 05 - 0. The elements such as 15%. Samarium cobalt magnet ': rare earth metal samarium Sm: 23 - 28% of rare earth metal cobalt Co: 48 - 52% iron metal element Fe: 14 - Copper metal elements Cu 17% : 5 - 2-7% zirconium is added a small amount of Zr: 3 ( 2) Different relative performance, the overall performance of the samarium cobalt magnet than ndfeb weaker! ( 3) Prices of different sizes of the same performance and samarium cobalt magnet ndfeb magnets, ndfeb were lower than the price of samarium cobalt! Of course both the proportion of metal elements can be seen from above! Ndfeb iron content is higher, the rare earth element content is less, and the price of iron is very cheap, so the summary of prices cheaper, samarium cobalt magnet samarium cobalt and rare earth elements content in the accounts for about 70%, so the price a little high! ( 4) High temperature resistance, oxidation resistance, corrosion resistant ability of different ndfeb iron content is very high, so easy to oxidation corrosion, so to do plating processing, largely depends on the service life of coating effect! And samarium cobalt magnet iron content accounts for only a small part, basically all is not easy to be oxidized corrosion of rare earth and metal elements, in general, do not need to make plating processing; However, using or in order to prolong the service life of the environment is poor, beautify the appearance, do electroplating processing will be better!
