Sintered NdFeb Magnets

Sintered NdFeb Magnets

Information

Sintered neodymium iron boron permanent magnet material came out in the early 1980s, the composition is not Nd2Fe14B. NdFeB permanent magnets are developing rapidly and widely used due to their excellent performance, abundant resources and reasonable price. Now it is widely used in micro motors, horns, toys, permanent magnet instruments, electronics industry, automobile industry, petrochemical industry, nuclear magnetic resonance devices, magnetic levitation systems, magnetic transmission mechanisms and magnetic therapy equipment. NdFeB magnets are easy to rust and oxidize, so the surface of NdFeB magnets usually need to be electroplated, such as galvanizing, nickel, gold, silver, etc., industry can be phosphated or sprayed with epoxy resin to slow down Its oxidation rate. It has extremely high magnetic properties, and its maximum magnetic energy product is more than 10 times higher than that of ferrite. Its own mechanical properties are also quite good, and it can cut and process different shapes and drill holes. The maximum operating temperature of high-performance products can reach 230 degrees Celsius.

Features

●Is made by powder metallurgy

●Very hard and brittle

●High resistance to demagneti-

-zation

If there is no proper coating or

electroplating, the material has

low corrosion resistance

●High cost/performance ratio

●General temperature stability
