Xaloy® X-8000™ Encapsulated Screws

The Xaloy X-8000™ coating is a thermal spray coating applied to the screw. This material complements Nordson’s high abrasive resistant Xaloy X-830® overlay and is well suited for processing highly filled or corrosive resins. It can be applied for the full flight length or only on isolated areas of the screw that are more susceptible to wear.

Benefits:

  • Tungsten carbide cladding – improved wear and superior corrosion resistance
  • Metallurgical bond – no chipping or delamination issues associated with HVOF carbide coatings
  • Rebuilt screws – Xaloy X-8000™ is repairable and can be applied to rebuilt screws

 

Features:

  • 100% metallurgical bonding to the screw base material
  • Typical bond strength is 280 megapascals
  • Complete Nordson Wear System – for the ultimate in wear protection:
    • Xaloy X-8000™ carbide cladding on the screw root surfaces
    • Xaloy X-830® carbide hardfacing on screw flight OD’s
    • Xaloy X-800® carbide barrel lining
