Excellent Machinability: Benefiting from its good ductility, Tungsten Carbide can easily handle various machining methods such as turning, milling, planning, threading, and tapping. It is also adaptable to large deformation strengthening processes like rolling, swaging, and forging, providing great convenience for manufacturing parts of various shapes.

Superb Ductility: Block products made of W-Ni-Fe high-density alloy exhibit a 10%-15% elongation in the sintered state. After vacuum or atmosphere dehydrogenation treatment, the elongation can be increased to 20%-30%, fully demonstrating its excellent ductility.

High Strength: The tensile strength of sintered Tungsten Carbide reaches 800-1000MPa, and it can be increased to 1300-1500MPa after heat treatment and deformation processing, highlighting its powerful mechanical properties.

Excellent Electrical Properties: Tungsten Carbide not only has good conductivity but also exhibits outstanding resistance to electrical erosion and high voltage, making it widely applicable in the electrical field.

Outstanding Thermal Conductivity and Low Linear Expansion Coefficient: Tungsten Carbide has a thermal conductivity five times that of mold steel, while its linear expansion coefficient is only 1/2 to 1/3 of that of iron or steel. This characteristic makes it excel in applications requiring efficient heat dissipation and stable dimensions.

Good Corrosion and Oxidation Resistance: Tungsten Carbide maintains stable performance in harsh environments, demonstrating excellent corrosion and oxidation resistance.

Excellent Weldability: High-density Tungsten Carbide can be easily brazed with copper, silver, and other welding materials, and it can also be electroplated, providing more possibilities for its application in various scenarios.
