On the characteristics of bonded NdFeB

Bonded NdFeB is a permanent magnet material which uniform mix the NdFeB powder and binder,then pressed by mold or injections, calendering, curing. Bonded NdFeB is a binder matrix phase, functional composite materials, which involves the magnetic powder binder interface (the surface of the magnetic particle processing), molding technology are concern of bonded NdFeB Institute. In the late 1960s, bonding process production of NdFeB became popular, compare with the original method of casting and powder metallurgy method (also known as sintering) production,NdFeB has the following characteristics:
1 It can be designed easily, the magnetic properties and shape can be designed according to the factual;
2 dimensional accuracy, free shape degrees, can precision into complex shapes of magnets once;
3 performance of magnetic are uniform and consistent;
4 good mechanical properties, high toughness, and easy to crack and burst angle;
5 can achieve large-scale automated production, high economic efficiency.

These advantages are made bonded NdFeB widely used in the field of computers, electronics industry, the automotive industry, office automation, home appliances, become the basic materials and device the high-tech industry.In addition, the density of bonded NdFeB is small,generally 50% -80% equivalent to the density of the dense material of the magnetic powder. The same time, the NdFeB powder and polymer binder, and bonded NdFeB magnetic low temperature of not less than higher, but this does not affect its overall performance of the magnet, the magnetic material in the fastest growing a class in recent years, the growth rate of over 20%.
