What is a super magnet?
_ ndfeb strong magnet manufacturers
Super strong magnet is & throughout;
Rare earth strong magnetic & throughout;
Professional title, is strong ndfeb magnet, because of their excellent magnetic known as & throughout;
The king of magnetic & throughout;
, ndfeb contains a large number of rare earth elements, neodymium iron and boron, its characteristics of hard and brittle.
Vulnerable to oxidation corrosion on the surface, ndfeb surface coating treatment must be conducted.
Surface chemical passivation is one good way to solve.
As rare earth ndfeb permanent magnet material of a magnetic energy product and high coercive force, high energy density at the same time the advantages of 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.
The advantage of ndfeb is cost-effective, good mechanical properties;
Shortcoming in low working temperature, 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 meet the requirements of practical application.
Ndfeb is divided into two kinds of sintered ndfeb and bonded ndfeb, every direction of bonded ndfeb magnetic, corrosion resistance;
And sintered ndfeb because easy to corrosion, surface coating, generally have galvanized zinc, nickel, environmental protection, environmental protection nickel, nickel and copper nickel, environmental protection, such as nickel, copper and nickel.
Sintered ndfeb magnets according to the maximum magnetic energy product size can be divided into low coercive force N, moderate coercive force M H, high coercive force, high coercive force SH, high coercive force, UH, high coercive force, EH, high coercive force TH seven products.
