Tungsten carbide or tungsten carbide, made from tungsten and carbon, is a very hard ceramic compound. Characteristic for which it is one of the most used materials in the manufacture of machines, tools and products used in the manufacture and work of steel.

Belonging to the group of carbides, this material is also known as ‘Widia’, a term that comes from the German expression ‘wie diamant’ (like diamond), and is present in a large number of mechanized cutting processes within the sector. industrial.

Frequently asked questions about Tungsten Carbide

 

What color is tungsten carbide?

Tungsten carbide has a solid, lustrous color, showing dark gray tones.

What is the structure of tungsten carbide?

There are two polymorphs of tungsten carbide. The hexagonal form, designated alpha, is stable at room temperature. It can also have a cubic structure, but it is only stable at very high temperatures.

What type of mineral is tungsten carbide?

It is not a material that is frequently found naturally, but we can find WO3

What kind of material is tungsten carbide?

It is a material of high hardness that belongs to the family of carbides.

What are the applications of tungsten carbide?

Thanks to its high hardness, thermal and chemical stability, it has numerous applications, ranging from the manufacture of machining tools to surgical instruments, through sports equipment and even jewelry.
