Adhesive：

Most levels of tungsten carbide is cobalt, and another adhesive is nickel. The amount of adhesive is a very important factor that determines the performance of each level. According to experience, the lower the cobalt content, the harder the materials.

Cobalt Quantity：

According to experience, the lower the cobalt content, the harder the materials. When more cobalt is added, it becomes softer and more resistant to impact. Because the less cobalt is added, the better its abrasion resistance, but it is easier to break when it is impacted.

The Size Of Granule：

The size of the micron particles we use is between 0.2 and 0.6, which is harder than standard particles with the same cobalt content. The size of the micron particles is more uniform, so it improves the strength and carbide strength. Smaller particles have better wear resistance, and larger particles have better impact resistance. The tungsten carbide with extremely fine particles provides very high hardness, while ultra -thick particles are most suitable for extremely serious wear and impact applications.

The minimum horizontal fracture strength (TRS), TRS is an index to measure tungsten carbide strength, which increases as the cobalt content increases.

Density：

Density is determined by the ratio of quality and volume, which is usually represented by G/CM3. High -density means better abrasion resistance and tough tungsten carbide. Usually they receive longer wear and better polishing effect. None of the cobalt percentage or particle size cannot determine the performance of the level separately. By changing the particle size and the cobalt percentage, you can make the hard alloy harder.

Mixed Material：

Tungsten carbide is much faster than tool steel. As the content of adhesive increases, thermal conductivity decreases.

Manufacturing Technology：

High corrosion resistance (tungsten carbide is an extremely stable substance that does not oxidize in the air at room temperature)
