Customized Tungsten Carbide Alloy Strip
Description
-
Characteristics of Tungsten carbide material
- High hardness:
- The hardness of tungsten carbide is extremely high, second only to diamond, which gives it excellent wear resistance. During the use of the valve, it can effectively resist the erosion and wear of the medium, extending the service life of the valve.
- Corrosion resistance:
- Tungsten carbide has stable chemical properties and is not easily reacted with corrosive media such as acid, alkali, salt, etc. It can be used for a long time in harsh corrosive environments without damage.
- High temperature resistance:
- The melting point of tungsten carbide is as high as 2870 ℃ (also known as 3410 ℃), which has good high temperature resistance and can maintain stable performance under high temperature conditions.
- High strength:
- Tungsten carbide has high strength and can withstand significant pressure and impact forces, ensuring stable operation of valves under harsh working conditions.

Characteristics of Tungsten carbide stripes
- Composition:
- Tungsten carbide alloy bars are usually composed of elements such as tungsten, cobalt, nickel, and iron. Among them, tungsten is the main component, providing excellent wear resistance and high temperature performance; Metals such as cobalt and nickel are used to enhance the hardness and toughness of alloys; Iron is used to reduce costs and improve compatibility with other metals.
- Manufacturing process:
- Excellent tungsten carbide alloy bars have a tight microstructure and uniform composition distribution, which is achieved through strict manufacturing processes and quality control.
- Chemical stability:
- Tungsten carbide is insoluble in water, hydrochloric acid, and sulfuric acid, but easily soluble in mixed acids of nitric acid and hydrofluoric acid. Pure tungsten carbide is fragile, but its brittleness is significantly reduced when a small amount of metals such as titanium and cobalt are added.

Advantages of Tungsten carbide stripes
- High hardness:
- Tungsten carbide alloy strips have extremely high hardness, which makes them perform well in environments with high pressure and wear.
- Wear resistance:
- Due to its high hardness and excellent wear resistance, the service life of tungsten carbide alloy bars is significantly extended, reducing replacement frequency and lowering production costs.
- Bending strength:
- Tungsten carbide alloy strips also have good bending strength and can withstand large bending forces without fracture.
- Corrosion resistance:
- It has good corrosion resistance to various chemicals and can maintain stable performance in harsh industrial environments.
-
Application of Tungsten carbide stripes
- Cutting tools:
- Tungsten carbide alloy bars are often used to manufacture high-performance cutting tools such as drill bits and cutting tools due to their high hardness and wear resistance.
- Wear resistant components:
- Tungsten carbide alloy strips are used as wear-resistant components in environments that require high wear resistance, such as parts in oil and gas drilling equipment, compressor parts, etc.
- Aerospace field:
- In the aerospace field, tungsten carbide alloy bars are used to manufacture key components such as high-temperature bearings and sealing rings to meet the needs of extreme conditions such as high temperature and high pressure.
- Other applications:
- In addition, tungsten carbide alloy bars are widely used in industries such as electronics, power, metallurgy, and machinery, as well as as as manufacturing materials for superhard cutting tools and wear-resistant semiconductor films.
