Tungsten Carbide vs. Boron Carbide: What's the Difference?
Edited by Janet White || By Harlon Moss || Published on January 22, 2024
Tungsten carbide is a hard, dense metal compound used for cutting tools and abrasion resistance, whereas boron carbide is a lighter, extremely hard ceramic used in ballistic armor and abrasive applications.
Key Differences
Tungsten carbide, a compound of tungsten and carbon, is known for its extreme hardness and high melting point, making it ideal for cutting and drilling tools. Boron carbide, a compound of boron and carbon, also boasts extreme hardness but is lighter, lending its use in lightweight ballistic armor.
In terms of density, tungsten carbide is significantly heavier, which is beneficial in industries requiring heavy-duty tooling. Boron carbide's lower density makes it preferable for applications where weight is a critical factor, like in body armor.
The manufacturing processes of tungsten carbide often involve powder metallurgy, while boron carbide is typically produced through carbothermal reduction. Both processes are complex and require precise control.
Tungsten carbide is known for its wear resistance, making it a top choice for industrial applications subjected to high wear and tear. Boron carbide, while also wear-resistant, is more renowned for its ability to absorb impacts, hence its use in protective gear.
In terms of cost, tungsten carbide is generally more affordable and widely used in various industries, whereas boron carbide's specialized applications, particularly in defense and aerospace, make it a more expensive material.
