Tungsten Carbide Grades

tungsten carbide Carbide Grade Chart
Raven Carbide Die will be more than happy to assist you in selecting the right grade of tungsten carbide for your carbide dies, punches or tooling. This will ensure that you receive the longest possible life out of your tooling. Sometimes tweaking the grades of carbide used can mean that thousands of additional parts can be run before it is necessary to replace dies.

Tungsten Carbide is graded by the percent of binder used, so a 12% grade carbide has 12% binder and 88% tungsten. The binder used is typically cobalt, although nickel binders can be used for special applications.
