Tungsten Carbide Strips

What is carbide strip?

Tungsten carbide Strips, also called tungsten carbide sheets, carbide round bar and tungsten carbide blocks, are one of the products made of tungsten carbide, and made by powder metallurgy through powdering, ball milling, pressing, and sintering. Cemented carbide strip is a composite material with excellent properties, consisting of a metal matrix and cemented carbide particles. It has the characteristics of high hardness, high strength, high wear resistance, and high corrosion resistance, and is widely used in various fields. The high performance of cemented carbide strips mainly comes from its high hardness, high wear resistance, good corrosion resistance, high thermal stability, good tool rigidity and impact resistance, and excellent thermal and electrical conductivity and other factors. These properties make carbide strips an ideal material for cutting and grinding tools, providing important support for the development of modern manufacturing.

How is carbide plate produced?

Powder→formulation according to application requirements→wet grinding→mixing→crushing→drying→sieving→then adding forming agent→drying again→sieving to make the mixture→granulating→ pressing→forming→sintering→forming (blank)→flaw inspection→packaging→warehousing.

Application of Cemented Carbide Strips

Below I will introduce in detail the common application fields of cemented carbide plates.

a. Manufacturing field

The first application field that uses carbide strips a lot is manufacturing field. Cemented carbide sheets are widely used in the manufacturing industry, one of the main field is the machining industry. To improve the hardness, wear resistance and corrosion resistance of the tools, tungsten carbide plates can be used to manufacture carbide inserts, carbide cutting tools, drills, milling cutters, turning tools, etc.,. Using carbide strips can also help prolonging the service life of the tools. In addition, cemented carbide plates can also be used to manufacture carbide molds, stamping dies, etc., Using carbide plates can also improve the wear resistance and compression resistance of the mold, and to increase the service life of the mold.

b. Aerospace field

The second field is the aerospace field. Cemented carbide sheets have important applications in the aerospace field. Due to its high hardness and good wear resistance, it can be used to manufacture aircraft, spacecraft and other parts that work in harsh environments of high temperature, high speed and high pressure, such as engine blades, combustion chamber panels, missile tails, etc. Tungsten carbide sheets can provide excellent wear and thermal shock properties, thereby ensuring the safety and reliability of aerospace vehicles.

c. Iron and steel metallurgy field

Cemented carbide plates are also widely used in the field of iron and steel metallurgy. In the process of iron and steel production, operations such as pouring and stirring of molten steel are frequently performed. Therefore, higher requirements are put forward for the wear resistance and corrosion resistance of the equipment. Tungsten carbide plates can be used to manufacture wear-resistant and corrosion-resistant sprue plates, stirring devices, etc. Thereby prolonging the service life of the equipment and improving the efficiency of steel production.

d. Mining engineering field

Cemented carbide plates are also widely used in the field of mining engineering. During the mining and processing of ore, it is often necessary to use wear-resistant materials to manufacture excavation tools, crushing equipment, screening machinery, etc. In order to improve the service life of equipment and reduce the frequency of maintenance and replacement, choosing tungsten carbide plates to manufacture mining equipment parts would be a great choice. 

e. Petrochemical field

Cemented carbide sheets also have important applications in the petrochemical field. In the process of petrochemical production, it is often necessary to use corrosion-resistant materials to manufacture various reactors, converters, storage tanks, pipelines and other equipment. Tungsten carbide plates have excellent corrosion resistance and can be used to manufacture corrosion-resistant equipment parts, improve the service life of equipment, and reduce maintenance costs.

f. Automobile industry

Carbide sheets are also widely used in the automotive industry. Auto parts usually need to have the characteristics of high strength, high hardness, wear resistance and corrosion resistance to meet the safety and reliability requirements of automobiles. Tungsten carbide plates can be used to manufacture engine cylinder liners, brake discs, crankshafts, clutches and other components to improve the performance and service life of automobiles.

g. Electronic and electrical field

The last field this article is going to talk about is electronic field. Cemented carbide sheets also have certain applications in the field of electronic appliances. Cemented carbide plates are often used to manufacture heat dissipation equipment such as heat conduction plates and radiators during the manufacturing process of electronic devices and circuit boards. Carbide plates help improve the heat dissipation performance of the equipment and ensure the normal operation of electronic devices.
