Metal carbides, non-agglomerated; mixed together or with metallic binders

HS v2017 Code: 382430

About metal carbides, non-agglomerated; mixed together or with metallic binders

HS code 382430 covers the classification of metal carbides, a critical class of materials used in a wide range of industrial applications. Metal carbides are known for their exceptional hardness, wear resistance, and high-temperature stability, making them essential components in the production of cutting tools, abrasives, and various other industrial products. This industry plays a vital role in supporting the manufacturing and construction sectors, contributing to the overall strength and competitiveness of the global economy.

Production process

The production of metal carbides typically involves a process known as carbothermal reduction. This method combines metal oxides, such as tungsten oxide or titanium oxide, with a carbon source, such as charcoal or petroleum coke, and heats the mixture to high temperatures, often exceeding 1,800°C. Under these conditions, the carbon reacts with the metal oxides, forming the desired metal carbide compounds. The resulting material is then crushed, milled, and processed into various forms, such as powders, granules, or shaped components, depending on the intended application.

Production inputs

The key inputs for the metal carbide industry include metal oxides, carbon sources, and various binders or additives. Common metal oxides used in this industry include tungsten oxide, titanium oxide, and chromium oxide, among others. The carbon sources can range from charcoal and petroleum coke to graphite and other carbonaceous materials. Additionally, metallic binders, such as cobalt or nickel, may be added to the mixture to enhance the mechanical properties of the final product.

Production outputs

The primary outputs of the metal carbide industry are the various forms of metal carbides, including tungsten carbide, titanium carbide, and chromium carbide, among others. These materials are widely used in the production of cutting tools, wear-resistant components, and abrasives, as well as in the manufacture of 820720 Interchangeable tools for hand tools or for machine-tools, 848610 Machinery and apparatus for the manufacture of semiconductor devices or of electronic integrated circuits, and 848620 Machines and apparatus for the manufacture of semiconductor devices or of electronic integrated circuits, which consume significant quantities of metal carbides.
