Defect analysis of cemented carbide compacts
Most defects in the precision and apparent quality of cemented carbide blanks occur during the pressing production process. Effectively controlling the occurrence of pressing defects is the key to ensuring the precision and apparent quality of cemented carbide blanks. With the development of prec...Read more -
Molding and Quality Control
Cemented carbide molding is to compact the mixed powder to obtain the required density and density uniformity, and the required shape. The process of producing compact shapes and dimensional accuracy requires that the compacted compact must have a certain strength. The relative density of the com...Read more -
Application of CIM in cemented carbide manufacturing
CIM is an organization in the information age, a philosophy for managing enterprise production, and a production model for new enterprises in the information age. The specific implementation based on this philosophy and technology is the Computer Integrated Manufacturing System, or CIMS. Well-kno...Read more -
Recycling and Utilization of Carbide
At present, there are several main categories of recycling processes for tungsten carbide.One is the so-called high-temperature treatment method, which includes: saltpeter melting method, air oxidation sintering method, oxygen calcination method, etc.; the other is mechanical crushing method, whi...Read more -
Carbide precision molding process
The ordinary pressing production process of cemented carbide is relatively simple. It only determines the pressing unit weight and pressing size of a certain model through pressure testing, and uses this as the production process parameters to implement it throughout. There are no clear requireme...Read more -
Submicron and ultrafine carbide
The submicron and ultrafine cemented carbide currently put into commercial production mainly consists of submicron and ultrafine WC, Co powder and appropriate grain length. It is prepared from large inhibitors (mainly Cr3C2, VC), and its grain size is 0.2~0.8μm. Due to the unique properties of s...Read more -
Cemented Carbide Products Tungsten Powder Preparation
Ultra-fine particle tungsten powder is black, fine particle tungsten powder is dark gray, and coarse particle tungsten powder is light gray with metallic luster. Metal tungsten powder can be produced by reducing tungsten oxide. The main reduction methods are hydrogen reduction and carbon reductio...Read more -
Carbide and cermet preparation
WC-Co hard alloys have good microwave adaptability. During the sintering process, the loss modes that work in the low temperature zone are mainly polarization relaxation loss and magnetic loss, while in the high temperature zone the alloy absorbs microwave energy. Mainly in the form of dielectric...Read more -
What die material is used for hot forging? (tungsten carbide hot forging die)
Hot forging die are usually made of materials such as H13 tool steel, which has high heat resistance, strength and toughness. Other materials such as D2 tool steel and high-speed steel can also be used for hot forging dies. These materials were chosen for their ability to withstand the high temp...Read more -
How hard is it to scratch tungsten carbide?
Tungsten carbide is extremely hard and is one of the hardest materials known. It’s even harder than titanium and steel. Tungsten carbide dies has a Mohs hardness of 8.5 to 9, second only to diamond, which has a hardness of 10. Therefore, it is difficult to scratch or damage tungsten carbide...Read more -
What are the disadvantages of tungsten carbide?
Tungsten carbide dies has several disadvantages, including: Brittleness: Tungsten carbide cold heading dies is brittle, which means it is prone to cracking or breaking under certain conditions. Limited Toughness: While tungsten carbide hot forging dies is very hard and wear-resistant, it has li...Read more -
