1. Basic knowledge of cemented carbide

Q1: What is cemented carbide?

A1: Cemented carbide is a composite material composed of refractory metal carbides (such as tungsten carbide, titanium carbide, etc.) and metal binders (such as cobalt, nickel, iron, etc.). These components are sintered at high temperatures using powder metallurgy methods, resulting in extremely high hardness, wear resistance and compressive strength.

Q2: What are the main application areas of cemented carbide?

A2: Cemented carbide is widely used in cutting tools, drilling tools, wear-resistant parts and other fields, especially in machinery manufacturing, automobile manufacturing, aerospace, electronics industry, petrochemical industry and other industries due to its high hardness and high wear resistance. Sex makes it an indispensable material.

2. Performance characteristics of cemented carbide

Q3: What are the physical properties of cemented carbide?

A3: Cemented carbide has physical properties such as high hardness, high wear resistance, high compressive strength and good thermal stability. These properties allow it to maintain good performance under high temperature, high pressure and harsh environments.

Q4: What are the advantages of cemented carbide compared with high speed steel?

A4: Compared with high-speed steel, cemented carbide has higher hardness, better wear resistance and higher cutting speed, which can significantly improve the service life and processing efficiency of tools.

3. Preparation and use of cemented carbide

Q5: What are the preparation methods of cemented carbide?

A5: The preparation methods of cemented carbide mainly include powder metallurgy and solution infiltration. The powder metallurgy method is formed by mixing carbide powder with a metal binder, pressing it, and then sintering it at high temperature; the infiltration method is to obtain cemented carbide by infiltrating metal.

Q6: What should you pay attention to when using cemented carbide?

A6: When using cemented carbide, attention needs to be paid to maintaining the sharpness of the tool to avoid excessive wear; at the same time, appropriate cutting parameters and coolant must be selected to ensure the processing effect and tool life.

4. Market and development of cemented carbide

Q7: What is the market prospect of cemented carbide?

A7: With the advancement of science and technology and the development of industry, the application fields of cemented carbide are constantly expanding, and the market demand continues to grow. It is expected that in the future, cemented carbide will achieve greater development in terms of high performance, high precision, and high reliability.

Q8: What is the future development trend of cemented carbide?

A8: The future development trend of cemented carbide will mainly focus on material innovation, process optimization and application expansion. By developing new carbide materials, improving preparation processes and improving product performance, the application of cemented carbide in various fields will be further promoted.

5. Other frequently asked questions

Q9: How to choose the appropriate cemented carbide product?

A9: When selecting cemented carbide products, comprehensive considerations need to be made based on the specific application fields, processing requirements and usage environment. You can consult a professional cemented carbide supplier or consult relevant literature for more detailed information and suggestions.

Q10: What is the price of cemented carbide?

A10: The price of cemented carbide is affected by many factors, including raw material cost, production process, product performance and market supply and demand. Generally speaking, high-quality cemented carbide prices are relatively high, but the specific price needs to be evaluated based on the specific product and application area.
