Chiamger, as a new brand, is initiated specially for hardfacing (also called hard facing, hard surfacing, hard overlaying or hard coating) & wear-resistant materials by WISDOM on Jan 1st, 2016. We manufacture a range of water and gas atomized powder with high quality for surface coating applications, based on cobalt, nickel and iron alloys.

There a comprehensive range of wear solutions for critical applications used in all types of surface engineering, applications and equipments, including:

  • Plasma Transferred Arc (PTA)
  • Laser Cladding
  • Spary & Fuse (Flame Spraying)
  • Powder Welding
  • HVOF
  • Plasma spray

The Wisdom's cobalt base materials are available in forms of rod, electrodes and powder. Regarding powder, which can be consumed through welding and thermal spraying processes, they are equivalent to certain grade of Stellite, Tribaloy, Weartech and Hoganas. Strictly in accordance with UNS standard, Wisdom's cobalt metals can be classified in following specifications.
