MCrAlY Powder 20-63 µm

MCrAlY Powder for Thermal Spray Applications

MCrAlY (where M = Ni, Co, or NiCo) powders form the backbone of many high-temperature coating systems. When applied via HVOF or plasma spray, these powders create dense, well-bonded coatings that protect base materials from oxidation, sulfidation, and other high-temperature degradation mechanisms up to and beyond 1000°C, depending on the specific alloy composition.

The 20–63 µm particle size distribution is engineered to suit a broad range of thermal spray equipment. This cut provides a practical balance: the lower end (20 µm) ensures good melting characteristics, while the upper end (63 µm) maintains sufficient mass for high deposit efficiency in HVOF and plasma guns. Tighter or custom cuts may be available to match specific gun parameters.

Key Considerations for Buyers

Selecting an MCrAlY powder involves more than just particle size. The specific alloy chemistry—whether NiCrAlY, CoCrAlY, or NiCoCrAlY—must be matched to the service environment. NiCrAlY grades typically offer superior oxidation resistance, while CoCrAlY grades excel in hot-corrosion conditions. NiCoCrAlY formulations aim to provide a balanced performance envelope.

We recommend that buyers prepare the following information when requesting a quotation to ensure the correct grade is proposed:

• Base material of the component being coated
• Operating temperature and environment (oxidation, hot corrosion, or both)
• Thermal spray process and gun model being used
• Required coating thickness and bond strength specifications
