1. Tungsten-Cobalt Cemented Carbides

As the most fundamental and widely used type of cemented carbide, tungsten-cobalt cemented carbides feature excellent hardness and wear resistance. These materials are primarily composed of tungsten carbide (WC) and cobalt (Co) and are manufactured via a powder metallurgy process. They are suitable for various cutting tools, mining tools, and wear-resistant parts. Key advantages include:

• High hardness, reaching HRA85-92
• High flexural strength, generally ranging from 1800 to 2200 MPa
• Outstanding wear resistance, resulting in a long service life

2. Tungsten-Titanium-Cobalt Cemented Carbides

By adding titanium carbide (TiC) to the base formulation, this type of cemented carbide retains basic performance while also offering:

• Higher heat resistance
• Excellent chemical stability
• Improved oxidation resistance

This material is particularly suitable for high-speed cutting, continuous cutting, and other demanding machining applications.

3. Tungsten-Titanium-Tantalum (Niobium) Cemented Carbides

This is a class of advanced composite cemented carbides. By adding tantalum or niobium elements, these products achieve:

• Greater toughness
• Better resistance to thermal shock
• Exceptional thermal stability

They are mainly used in heavy-duty cutting, interrupted cutting, and similar applications.

Selection Guidelines

• Choose the appropriate grade based on specific application scenarios.
• Consider the intended use—whether for cutting tools, wear-resistant parts, high-temperature components, die parts, etc.—along with factors such as operating temperature and applied stress.
• Balance economic considerations with service life.
