Tungsten carbide (tungsten steel)

Q:

1、 Hard alloy manufacturing

Hard alloy is a material made by mixing hard powders such as tungsten carbide with metal powders, and then pressing, sintering, and other processes. It has both the strength and toughness of metals, as well as the hardness and wear resistance of carbides, making it widely used in industries such as cutting, stamping, mining, and oil drilling.

2、 Manufacturing of superhard materials

Superhard materials refer to materials that are harder than hard alloys, mainly made of superhard substances such as tungsten carbide and titanium carbide. It has excellent properties such as high hardness, wear resistance, and high thermal strength, and is widely used in aerospace, electronics, optics, and other fields.

3、 Cutting tool manufacturing

Tungsten carbide is one of the important raw materials for manufacturing cutting tools. Due to its high hardness, wear resistance, and good heat resistance, it can be used to manufacture milling cutters, drill bits, turning tools, planers, blades, etc. At present, tungsten carbide cutting tools have become the mainstream product in aerospace, mechanical manufacturing and other fields.

4、 Nozzle manufacturing

Tungsten carbide has high melting point, high hardness, and high thermal conductivity, making it an excellent raw material for manufacturing high-temperature nozzles. It is commonly used in the nozzle manufacturing of rocket engines.

5、 Manufacturing of vacuum electronic devices

Tungsten carbide has properties such as high thermal stability, low vapor pressure, and high conductivity, and is one of the important raw materials for manufacturing vacuum electronic devices, such as cathode tubes and ceramic vacuum tubes.

6、 Alloy additives

Tungsten carbide can be used as an alloy additive to improve the hardness, wear resistance, and high-temperature performance of alloys. It is commonly used in the manufacturing of high-speed steel, stainless steel, high-temperature alloys, etc.

7、 Graphite electrode manufacturing

Graphite electrodes are important tools for the melting of cast iron and steel, and their main raw materials are graphite and carbides. The addition of tungsten carbide can improve the conductivity and mechanical properties of graphite electrodes, while reducing their oxidation and erosion, thereby extending their service life.

Q:

Tungsten carbide is harder than titanium alloy, with a hardness of up to 2400-3000Kg/mm ²， And the hardness of titanium alloy is only 280~420Kg/mm ²。

Q:

Tungsten carbide ceramics have many advantages, such as high hardness, high temperature resistance, oxidation resistance, etc., but there are also some limitations, such as:

1. Easy to fracture: Tungsten carbide ceramics have high brittleness, so excessive impact and vibration should be avoided during use.

2. Difficult to process: Due to its extremely high hardness, the processing difficulty of tungsten carbide ceramics is also significant, requiring specialized equipment and processes.

3. Expensive: Due to high production costs, tungsten carbide ceramics are relatively expensive and not suitable for large-scale applications.

In summary, tungsten carbide ceramics are a very excellent engineering ceramic material with broad application prospects. When choosing to use tungsten carbide ceramics, it is necessary to scientifically select and design materials based on their advantages and limitations
