NiCrAlY powder

NiCrAlY powder is one kind of spraying powders with Y-doped for adhesion. It has good high-temperature oxidation up to 1100 and corrosion resistance. It can form a protective alumina (Al2O3) scale at elevated temperatures, making it ideal for gas turbine components by thermal spray coatings (HVOF, plasma spray) or additive manufacturing (LPBF, DED).

Its chemical composition can be customized, including NiCrAlY, FeCrAlY, NiCoCrAlY and CoNiCrAlY (higher melting point with Co-based).

Product Description

Its chemical composition can be customized, including NiCrAlY, FeCrAlY, NiCoCrAlY and CoNiCrAlY (higher melting point with Co-based).

Our common production process includes Gas Atomizing process (GA) & Plasma Rotating Electrode Process (PREP) with high spherical, high purity, high packing density, low porosity and excellent flowing properties.

The particle size can be customized by customer’s needs, normally our PSD 15-45um or 15-53um for LPBF, 45-106um for DED and 5-45um for HVOF or plasma spray.

Applications

How we play a role in the industry

HIP Technology

Hot Isostatic Pressing (HIP) technology works by placing the product in a closed container, filling it with inert gas and sintering or densifying the product at a very high temperature (usually close to the forging temperature of the material) and at a very high pressure (usually 100 – 140 MPa). This allows the product to be sintered or densified.

MIM Technology

MIM products can be complex in shape, precise in size, high in strength and produced automatically in large quantities, and can significantly reduce the complexity and cost of traditional metalworking

SLM Technology

SLM, also known as Selective Laser Melting, is similar in principle to SLS in that a laser is used to melt and solidify metal powder in a specified area, which is then moulded in a layer-by-layer stack.

EBM Technology

Electron beam melting refers to a vacuum melting method in which the kinetic energy of a high speed electron beam stream is converted to heat as a heat source for melting metals under high vacuum. The abbreviation is EBM.
