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.

See Praxair Surface Technologies, Inc, Co and Ni based MCrAlY options below.
