Manufacturing supports modern civilization by machining iron, cement, copper, glass, plastics and various other materials. 
Carbide tools are one of the major tools used in this machining. These tools are made from cemented carbide, which 
combines tungsten carbide (WC) and cobalt (Co). Carbide tools have three main applications; 

1) rock drilling tools, essential for mine excavations and infrastructural development for tunnels and roads, and

2) cutting tools for automotive and aerospace machining applications;

3) wear resistant tools used as molds for sanitary goods manufacturing, rolls for metal rolling, coating tools for LCD 

    television displays and more.

Mitsubishi Materials carbide manufacturing system integrates development,  manufacturing and recycling of materials 

through to the fi nished product.
