Does Tungsten Carbide Conduct Electricity? Explained.
Tungsten carbide is a popular material that is used in a wide range of industries, from automotive to aerospace. A common question that people tend to ask is whether or not tungsten carbide conducts electricity. In this article, we will explore the answer to this question in a step-by-step manner.
Step 1: Understanding the Composition of Tungsten Carbide.
Tungsten carbide is a composite material that consists of tungsten carbide particles as well as a metallic binder. The most commonly used binder is cobalt, although nickel and other alloys can also be used. The proportion of tungsten carbide to the binder material varies depending on the application, but typically ranges from 70:30 to 94:6.
Step 2: Examining the Conductivity of Tungsten Carbide.
Tungsten carbide is an electrically conductive material, but its conductivity is not as high as copper or aluminum. Its electrical conductivity is similar to that of iron or steel. Tungsten carbide also exhibits a low thermal expansion coefficient and high thermal conductivity, making it an ideal material for use in high-temperature applications.
Step 3: Understanding the Role of the Binder in Conductivity.
The metallic binder in tungsten carbide can affect its conductivity. Cobalt, the most commonly used binder material, is slightly conductive itself. However, when tungsten carbide and cobalt are combined, the conductivity of the resulting material is reduced due to the insulating properties of the tungsten carbide particles. This reduction in conductivity is not significant for most practical applications.
Step 4: Investigating the Usefulness of Tungsten Carbide’s Conductivity.
The electrical conductivity of tungsten carbide is not as high as other metals, as we have already mentioned. However, it is still useful in certain applications. For example, tungsten carbide is commonly used in the production of electrical contacts and electrodes due to its resistance to wear and high temperature resistance.
In conclusion, tungsten carbide is an electrically conductive material, but its conductivity is not as high as other metals like copper or aluminum. Its electrical conductivity is similar to that of iron or steel. The metallic binder in the material can affect its conductivity, and tungsten carbide’s conductivity is reduced due to the insulating properties of the tungsten carbide particles. Despite this reduction, tungsten carbide is still useful in certain applications where its resistance to wear and high temperature resistance make it a preferred material for use in electrical contacts and electrodes.
