FAQs

1. What are the primary applications of tungsten carbide in China?

Tungsten carbide finds extensive use in cutting tools, wear-resistant parts for machinery, mining equipment, and dies for metal forming. Its high hardness and durability make it ideal for these demanding applications.

2. How does the cobalt content in tungsten carbide affect its properties?

The percentage of cobalt acts as a binder, influencing the material’s toughness and maChinability. Higher cobalt content typically leads to increased toughness but reduced hardness.

3. What are the main regions in China that produce tungsten carbide?

Hunan, Jiangxi, and Fujian provinces are known for their substantial tungsten resources and high concentration of tungsten carbide manufacturing facilities.

4. Are there any environmental concerns associated with tungsten carbide production?

Yes, tungsten mining and processing can raise environmental concerns regarding water pollution and waste disposal. Sustainable practices are crucial for mitigating these impacts.

5. What is the difference between cemented carbide and binderless tungsten carbide?

Cemented carbide comprises tungsten carbide particles bound by a metal binder (usually cobalt), offering a balance of hardness and toughness. Binderless tungsten carbide, lacking a binder, boasts extreme hardness but is more brittle.
