Tungsten Carbide Cold Heading & Extrusion Die Blanks
Tungsten carbide die blanks and inserts for cold heading, cold forging and extrusion of bolts, screws, rivets and nuts.
Cold heading dies take repeated high-impact loading. The carbide must resist wear at the working surface without chipping or cracking under shock.
Typical applications
- Bolt, screw and rivet heading dies
- Nut forming and extrusion dies
- Cold forging inserts
What we supply
- Die blanks and inserts to your drawing
- Blanks for shrink-fitting into steel cases
Choosing the grade
High-cobalt, impact-resistant grades are the usual family for heading dies; the right level depends on the forming load and part geometry. Share the process and the part.
Grade data (binder content, grain size, hardness, density, transverse rupture strength) is confirmed in writing for the grade we propose. How we choose grades →
