• • ndfeb magnets, ndfeb is found that magnet, the highest commercial performance known as magnetic king, has the extremely high magnetic to its maximum magnetic energy product (
Above ferrite (
More than 10 times.
Machining properties of its itself is also quite good.
Working temperature up to 200 degrees Celsius.
And the quality of a material is solid, stable performance, good cost performance, so its application is very extensive.
But because of its strong chemical activity, so must the surface coating treatment.
Such as zinc plating, Ni, electrophoresis, passivation, etc. )
• • features: nd-fe-b materials based on Nd2Fe14B intermetallic compounds of permanent magnetic material.
Ndfeb has a very high magnetic energy product and JiaoLi, at the same time, the advantages of high energy density makes the ndfeb permanent magnet material in modern industry and the wide application of electronic technology, so that the instruments and meters, electronic motor, magnetization of the magnetic separation equipment miniaturization, lightweight, thin become possible.
• • material characteristics: the advantage of ndfeb is cost-effective, good machining properties;
Lack of Curie temperature in low point, temperature characteristic is poor, and is easy to be pulverization corrosion, must through the adjust its chemical composition and take surface treatment methods to improve, to reach the requirements of practical application.
