1. Cobalt plays an important role in tungsten carbide cutting tools

Tungsten carbide particles are difficult to joint to each other if there are no intermedia in between. Researchers have found that cobalt’s liquid phase has ability to reinforce the microstructure of tungsten carbide, forming a composite of metal and ceramic, Cobalt acts as an adhesive in tungsten carbide cutting tools.

2. Differences and effects of Cobalt content in tungsten carbide cutting tools

When the amount of cobalt is more, the tungsten carbide material is relatively soft, but more impact resistant. The most widely used tungsten carbide rods usually contain 10wt% of cobalt. This composition has sufficient toughness and hardness, suitable for cutting tools that requires high wear-resistance, high impact strength, and high tolerance of chipping.

3. In the field of machining, the cutting tool wear and life are extended by changing the proportion of cobalt

The most widely used tungsten carbide rods usually contain 10wt% of cobalt, But due to the current innovation and progress of industrial applications, in the field of machining, in order to extend the wear and life of the cutting tool, Tungsten carbide raw material suppliers provide different cobalt content bars, currently on the market, the proportion of cobalt include 5wt%, 10wt%, 12wt%, and 20wt%.

4. Different workpiece materials, machining conditions, there are different tungsten carbide raw materials for application

At present, the material of metal workpieces is more and more, and each metal workpiece material has different characteristics, these characteristics will affect the wear and life of the cutting tool. Tungsten carbide raw materials manufacturers have developed new tungsten carbide materials for different metal workpiece materials. They will publish regularly.

5. The selection rules of Baoje cutting tool on tungsten carbide bar

The slogan of Baoje Cutting Tools is quality first, to ensure the most stable and best cutting tool quality for customers. Therefore, we use the tungsten carbide bar that is the most famous brand in the world, Tungsten carbide raw materials are imported from Europe, America and Japan, for special machining development cases, we provide different tungsten carbide materials for customers to perform cutting tool wear test.
