Advantages of microwave sintering of tungsten alloy

The microwave sintering of tungsten alloy is to achieve sintering and densification of tungsten alloy products by making use of the dielectric loss of tungsten alloy material in microwave electromagnetic field and making the material to sintering temperature.  

Microwave heating has uniform temperature field and low thermal stress, which is suitable for rapid sintering.  In addition, the effect of microwave electromagnetic field can promote diffusion and accelerate sintering process, which can refine the grain of tungsten alloy material, effectively restrain the abnormal growth of grain, and improve the uniformity of material microstructure. 

The rapid heating reduces the grain coarsening caused by surface diffusion (mainly in the low temperature stage of traditional sintering), and provides a stronger driving force and a shorter diffusion path for grain boundary diffusion and volume diffusion, which results in the refinement of the microstructure of tungsten alloy and promotes the rapid densification of the body.  

Zhuzhou Jinxin adopts high-precision automatic equipment, the product production precision is higher, each semi-finished process, to the finished process, we have quality inspection personnel to participate in the detection, found problems in time, to ensure that tungsten alloy and other products factory qualified.
