Detail Comparison of Tungsten Metal and Tungsten Carbide Properties
Melting point: Tungsten has a higher melting point than tungsten carbide. Tungsten has a melting point of 3,422 degrees Celsius, while tungsten carbide has a melting point of around 2,870 degrees Celsius.
Corrosion resistance: Tungsten is more resistant to corrosion than tungsten carbide. This is due to the oxide layer present on tungsten, making it a more suitable material for cutting tools and ammunition.
Ultimate compressive strength: Tungsten carbide has a higher ultimate compressive strength compared to tungsten. Tungsten carbide is commonly used in cutting tools and armor-piercing ammunition due to its high strength.
Modulus of elasticity: Tungsten has a higher modulus of elasticity compared to tungsten carbide. This indicates that tungsten is better at resisting deformation under stress.
Electrical conductivity: Tungsten is more electrically conductive than tungsten carbide. This makes tungsten suitable for applications requiring high conductivity, such as in light bulb filaments.
Ductility: Tungsten is more ductile than tungsten carbide, meaning it can be easily bent and deformed without breaking, unlike tungsten carbide which is brittle.
Yield stress: Tungsten carbide has a higher yield stress compared to tungsten. This means tungsten carbide can withstand more stress before deforming permanently.
