Top 5 Uses For Tungsten Carbide - Carbide USA

30/11/2013· Surgical tools are one of the most notable uses for grafted carbide as the stem of the tool is typically made of stainless steel or titanium, while the blade, tip, or end is made from carbide. Not only can carbide blades be sharpened to have a much finer edge due to the material’s hardness, but its resistance to pitting and rusting helps to give tools tipped with it much greater longevity.
