Kennametal Stellite Nickel Powders

Astro Alloys offers Kennametal Stellite™ nickel powders. These nickel thermal spray powders work particularly well in high-temperature environments. These are available in a variety of sizes and specifications.

Deloro Nickel Alloys

The Deloro family of nickel powders offer good corrosion properties and are resistant to abrasion and wear.  They also retain their hardness up to 600ºC (1000ºF) with strong resistance to oxidation.

The most commonly used Deloro nickel alloys are:


Nistelle Nickel Alloys

The Nistelle family of nickel powders exhibit superior corrosion properties. These nickel-based alloys were developed to combat aggressive chemicals and other corrosive media. Nistelle nickel alloys also have excellent high-temperature strength and resistance to oxidation. 

The most frequently used Nistelle nickel alloys are:

  • Nistelle 625
  • Nistelle 718
  • Nistelle C
  • Nistelle C276
  • Nistelle X
  • Nistelle Super C

Tribaloy Nickel Alloys

The Tribaloy nickel powders were developed for applications in which extreme wear is combined with high temperatures and corrosive media.  They also work well for use in adhesive (metal-to-metal) wear situations. The Tribaloy family of nickel alloys feature a hard inter-metallic laves phase, dispersed in a tough matrix of eutectic or solid solution.  

The most commonly used Tribaloy nickel alloy is:

  • Tribaloy T-700
