Sintered NdFeB is made of neodymium, iron and boron. Among the ingredients, Nd2Fe14B has high magnetic properties. Jingda's magnetic energy product is more than 10 times that of ferrite magnets; the maximum working temperature can reach 250 degrees Celsius.
NdFeB has excellent mechanical properties and can be used in non-returning processing modes such as drilling, cutting, wire cutting, etc.

High corrosion resistance can be achieved through different surface coatings such as zinc, nickel, tin, silver, gold, phosphor and spray epoxy resin.
NdFeB is widely used in various industries due to its superior performance. It is mainly used in micromotors, special motors, permanent magnet instruments, electronics industry, automobile industry, petrochemical industry, nuclear magnetic resonance, audio equipment, magnetic levitation systems, magnetic transmission structures and magnetic therapy equipment, etc.
