کاربرد |
ZTC7232K1 |
This grade mainly consists of cast tungsten carbide and macrocrystalline tungsten carbide, a popular grade in most PDC bits plants. By controlling particle size, the powder has a higher apparent density and tap density, which shows superior wear and erosion resistance than other tungsten carbide matrix powders. | Mainly used in erosion-resistant, wear-resistant, and impact-resistant infiltration drill products. |
ZTC7232K2 |
This grade mainly consists of cast tungsten carbide and macrocrystalline tungsten carbide. The optimized particle size distribution gives the product excellent wear resistance after infiltration. | Mainly used in harsh working conditions that are easy to wear and erosion. |
ZTC7232K3 |
This grade mainly consists of cast tungsten carbide, macrocrystalline tungsten carbide, and nickel powder. By controlling particle size, the powder has a higher apparent density and tap density, which shows combined wear, erosion, and impact resistance. | Mainly used in erosion-resistant, wear-resistant, and impact-resistant infiltration drill products. |
