Cemented carbide sintering process flow
The sintering of cemented carbide is liquid phase sintering, that is, it is carried out under the condition that the bonding phase is in liquid phase. The compact is heated to 1350C-1600C in a vacuum furnace. The linear shrinkage of the compact during sintering is about 18%, and the volume shrink...Read more -

What is tungsten carbide powder
Tungsten carbide powder (WC) is the main raw material for the production of cemented carbide, with the chemical formula WC. The full name is tungsten carbide powder. It is a black hexagonal crystal with a metallic luster and a hardness similar to diamond. It is a good conductor of electricity and...Read more -
Analysis of the shortcomings of cemented carbide
1. Easy to expand due to heat Cemented carbide is prone to thermal expansion problems during high temperature and cooling processes. The main reason is that the thermal expansion coefficient of cemented carbide is larger than that of ordinary metals. This means that in high temperature environmen...Read more -
The disadvantages of cemented carbide mainly include the following points:
Hot cracking defects: Carbide is prone to hot cracking at high temperatures. This is mainly because cobalt may react with carbides at high temperatures to form harmful phases, thereby reducing the toughness and reliability of the material Porosity defects: Carbide contains pores. These defects a...Read more -
The difference between YG15 YG20 YG8 Grade
1. Which one has better impact resistance, yg+15 or yg+20: YG15 and YG20 are two grades of cemented carbide. There is no good or bad, it just depends on what occasion you use it. YG15 contains about 15% cobalt, has higher hardness than YG20, and lower strength than YG20. 2. Which one is easier t...Read more -
