Cemented tungsten carbide, also known as tungsten carbide alloy, is a composite material made of tungsten (W), carbon (C), and alloying elements such as cobalt or nickel. The Mohs hardness of tungsten carbide typically ranges between 8.5 and 9.5, and it can even be higher. Thanks to this exceptional property, it offers outstanding resistance to wear and scratches, making it far harder than most metals and alloys. In fact, it’s about 10 times harder than gold, 5 times harder than tool steel, and 4 times harder than titanium.

This extraordinary hardness allows the tungsten carbide rings They retain their shape and shine for a long time. For this reason, they are also known as "rings of permanent brilliance," as they maintain their appearance unchanged over the years.

Tungsten carbide also exhibits excellent chemical stability and corrosion resistance, enduring the erosion of most chemicals. It retains its hardness and structural integrity even at high temperatures, making it ideal for demanding environments involving friction or the risk of mechanical wear.

In summary, whether in industrial applications (seals, cutting tools, gears) or in high-strength jewelry, tungsten carbide rings deliver outstanding performance and unmatched durability.
