MCrAlY Spray Powders

MCrAlY spray powders are composed of nickel (Ni) or Cobalt (Co) or can be a combination of both. Cobalt & Nickel MCrAIY powders serve as the foundation for gas turbine hot section thermal spray coatings. Praxair creates them using the industry’s most advanced vacuum induction melting/argon gas atomization (VIM/AGA) technology. This results in high-purity, low-oxide original equipment manufacturer (OEM) approved powders. These superior cobalt & nickel MCrAlY powders result in superior high-temperature oxidation and corrosion-resistant coatings.
