Bishilite engine valves

Features

Made by adding elements such as chromium and tungsten to a cobalt base, these highly versatile wear-resistant alloys offer outstanding wear and oxidation resistance, and are subject to virtually no change in their properties.
Depending on the additives used, they can also be made exceedingly heat resistant, rendering them suitable for use in aircraft and ship engines, etc.

Applications

They can be welded to components subject to high wear and used to strengthen metal surfaces.

  • Hardfacing material (weld overlays)
  • Seat surfacing for ordinary valves
  • Automotive engine valves, marine engine valves
  • Surface hardening material for worms, screws, knives, and cutters
