China Tungsten online produces various types of ready to press powders which is widely used in manufacture of cemented carbide.The products have the following characteristics:
1、Stable apparent density
2、Excellen flowability thanks to spherical aspect of the powder
3、Good compressibility
4、High chemical purity,well control of carbon content
5、The cemented carbide made of our RTP has excellent physical properties
