Die, Tungsten Carbide

The most commonly used die material, it is most often used for ferrous drawing applications. Normal wire die sizes using carbide is .020 to 19.05 mm (.008 to .750 in.). Carbide is softer than diamond but is a tougher and less expensive material that can be reworked into larger sizes more than its diamond counterpart. It often is replaced by diamonds, however, when either increased die life and/or closer diameter tolerance is required.
