Tungsten Carbide

Product catalog summary

General Information
Tungsten Carbide materials are known for their high compressive strength, hardness, and wear resistance, along with the ability to withstand shock and impact. These properties make them suitable for applications such as valves, flowmeters, ball screws, linear bearings, ballizing, gauging, and ball pens.
