What Is Carbide

Carbides are compounds composed of carbon and one or more metallic elements. They are typically very hard and have a wide range of industrial applications due to their unique properties. The most well-known example is cemented carbide, also known as tungsten carbide, which consists of tungsten and carbon atoms and is often used in cutting tools, mining equipment, and wear-resistant parts.They find applications in various industries, including manufacturing, mining, aerospace, electronics, and more. The properties of carbides make them suitable for cutting, drilling, machining, and shaping tough materials, as well as for withstanding high temperatures and harsh environments.

The Type Of Cemented Carbide

Carbides consist of carbon bonded to an element with lower electronegativity, often a metal or metalloid. This elemental combination results in compounds with diverse characteristics, depending on the specific element involved. The carbon atoms can form various types of chemical bonds, leading to a wide range of carbide structures.Carbides can be categorized into different types based on their composition and structure:

  • Ionic Carbides: These carbides are formed by the reaction of metals with carbon at high temperatures. Examples include calcium carbide (CaC2) and aluminum carbide (Al4C3).
  • Covalent Carbides: These carbides are characterized by strong covalent bonds between carbon atoms and the metal atoms. Silicon carbide (SiC) is a prominent example of a covalent carbide and is used in abrasive materials, refractories, and electronic applications.
  • Interstitial Carbides: These carbides are formed when carbon atoms occupy the interstitial sites in a metal’s crystal lattice. Tungsten carbide (WC) and titanium carbide (TiC) are common interstitial carbides known for their hardness and wear resistance.
  • Transition Metal Carbides: These carbides are often formed by transition metals like titanium, tungsten, and chromium. They have high melting points and are used in applications requiring extreme heat and wear resistance.

Metal Carbides

Metal carbides are perhaps the most well-known and extensively studied class of carbides. These can be further categorized into:

  • Binary Metal Carbides: These carbides are composed of a metal and carbon. Tungsten carbide (WC) and titanium carbide (TiC) are prominent examples, celebrated for their exceptional hardness and wear resistance.
  • Intermetallic Carbides: These complex carbides result from the combination of two or more metals with carbon. They often exhibit unique properties that can be tailored for specific applications.

Non-Metal Carbides

Non-metal carbides involve carbon combined with non-metal elements like boron, silicon, or aluminum. Boron carbide (B4C) stands out due to its exceptional hardness and low density, making it suitable for armor and ballistic applications.

From their intriguing chemical structure to their myriad applications spanning industries, carbides have etched their place in modern technology and innovation. The unique combination of carbon and other elements yields compounds with exceptional properties, shaping the landscape of materials science, engineering, and manufacturing.

What Is Carbide Machining

Precision machining of carbide parts is a specialized manufacturing process that involves the creation of intricately designed components using carbide materials. Carbide, composed of tungsten carbide (WC) particles bonded within a cobalt matrix, offers exceptional hardness, wear resistance, and thermal stability. This unique combination of properties makes carbide a sought-after choice for crafting components that demand tight tolerances, intricate geometries, and superior performance in challenging environments.

Carbide Turning

Carbide Turning

Carbide turning is a fundamental machining process that involves the use of carbide cutting tools to shape and contour a rotating workpiece.

Leveraging the exceptional hardness, wear resistance, and heat stability of carbide materials, this technique allows for accurate and efficient material removal. Carbide turning is a cornerstone of modern manufacturing, serving industries such as aerospace, automotive, and general engineering.

Carbide Milling

Carbide milling is a high-precision machining process that involves using carbide cutting tools to remove material from a workpiece, resulting in the creation of intricate shapes, contours, and surfaces.

The use of carbide, a composite material comprising tungsten carbide particles bound in a cobalt matrix, empowers this process with exceptional hardness, wear resistance, and heat stability. Carbide milling has become an essential technique in modern manufacturing, contributing to industries ranging from aerospace to electronics.

Carbide Milling

Electrical Discharge Machining

EDM is a non-traditional machining method that uses electrical discharges to erode material from the workpiece. Carbide parts, which are electrically conductive, are precisely shaped using this technique. Wire EDM and sinker EDM are both employed for carbide machining, allowing intricate designs and complex shapes to be realized.


Grinding is crucial for achieving tight tolerances and superior surface finishes on carbide parts. Precision grinding machines equipped with diamond or cubic boron nitride (CBN) wheels offer exceptional material removal capabilities. Coolant usage is essential to dissipate heat and prevent workpiece damage.

Powder Sintering

Powder sintering of carbides is a common manufacturing process used to produce dense and high-strength carbide materials, which are often utilized in various industrial applications such as cutting tools, wear-resistant parts, and components for aerospace and automotive industries. Sintering is the process of compacting and forming a solid mass from powdered materials using heat and pressure.

Drilling Carbide

Drilling carbide materials can be a challenging task due to their high hardness and wear resistance. If you’re not experienced with drilling hard materials, it might be a good idea to consult experts or professionals who specialize in machining and drilling carbide.
