MCrAlY Materials for High Temperature Applications

When you need superior protection against high-temperature oxidation and hot corrosion, or a bond coat for the harshest of dynamic service environments, we recommend thermal spray coatings of our MCrAlY materials.

MCrAlY Materials for High Temperature Applications
Designed for the Hottest Service Environments

MCrAlY thermal sprayed coatings are used in the hottest sections of gas turbine engines and other high-temperature, corrosive environments. They can be used alone as an anti-corrosion coating or as a bond coat to improve the performance of Thermal Barrier Coating (TBC) systems or ceramic abradable coating systems. In addition, MCrAlY materials can be considered for other hot, corrosive environments, such as flue gas stacks.

MCrAlY Compositions for Demanding Applications
  • NiCrAlY materials protect against oxidation in high temperature gas environments
  • CoCrAlY chemistries offer excellent resistance to hot corrosion (sulfidation)
  • NiCoCrAlY or CoNiCrAlY materials provide an acceptable balance of both oxidation and sulfidation resistance

We also have proprietary Cobalt and/or Nickel MCrAlY Alloy Powders.

Highly Consistent Product Quality

We manufacture all our MCrAlY materials using inert gas atomization. This assures consistent and homogeneous chemistry of the powder particles. Our freely flowing powders feed exceptionally well when thermal spraying.

Choice of Optimized Particle Size Distributions

Many of our MCrAlY materials are available with different particle size distributions, designed for suitability using different thermal spray processes:

Trusted Product Reliability

As a testament to the quality and reliability of our MCrAlY thermal spray coatings, our products can be certified for a broad range of OEM material specifications. Many OEMs turn to us to be their proprietary MCrAlY material manufacturing partner. These proprietary products are available only to users authorized by the OEM.
