M2 is molybdenum based high-speed steel in tungsten?molybdenum series. The carbides in it are small and evenly distributed. It has high wear resistance. After heat treatment, its hardness is the same as T1, but its bending strength can reach 4700 MPa, and its toughness and thermo-plasticity are higher than T1 by 50%.
It is usually used to manufacture a variety of tools, such as drill bits, taps and reamers. Its decarburization sensitivity is a little bit high.

The bonded NdFeB magnets are mainly used for all kinds of small and micro-motors, such as spindle motors, stepping motors, synchronous motors, DC motors and brushless DC motors. It can replace sintered NdFeB magnet and ferrite, make motor assembling simpler and more reliable, reduce costs and improve efficiency. The bonded NdFeB magnets are made by mould pressing of the NdFeB alloy powder with epoxy resin, and also it can be made by injection or extrusion of NdFeB alloy powder with plastic. The characteristics are as follows:
1.Higher magnet property: the magnet property of bonded NdFeB magnets is between that of sintered NdFeB and Ferrite, and has good consistency and stability.
2.Large freedom of product shapes and high precision of dimension: the magnet shape and dimension are decided by the moulds, and the magnets can be shaped into ring, tile, block, etc. without further sintering and mechanical processing.
3.Good corrosion resistance: after electrophoresis or other special treatments, it can be used under normal or unfavorable conditions for a long time.
4.Diverse magnetization: multi-pole magnetization and skew-pole magnetization are available, and the field distribution could be square, sinusoidal and so on.
5.It has high production efficiency, and is suitable for mass production.
