Hot Extrusion

The tools used in hot extrusion of both ferrous and non-ferrous alloys are subject to high forming pressures, severe abrasive wear, adhesive wear driven by corrosion and very high temperatures. Ionbond™ PVD and Bernex™ CVD coatings exhibit the toughness, wear resistance, corrosion resistance, and thermal stability necessary in order to significantly enhance tool productivity. Bernex™ CVD coatings are often the best option for complex geometry and large aspect ratio tools.

Bernex™ 08, Bernex™ 10, or Bernex™ 29 are suitable for open tolerance tooling, while Ionbond™ 35, Ionbond™ 22, or Ionbond™ 30, all coupled with nitriding, are coatings suited for hot extrusion tools with close dimensional tolerances.
