What Makes K465 Alloy Powder a Preferred Choice for High-Temperature Turbine Components

Published by HUAXIAO TECH manufacturer

K465 alloy powder is a nickel-based superalloy engineered for demanding applications involving high temperature, high pressure, and extreme mechanical stress. Its balance of strength, creep resistance, and corrosion resistance makes it a key material for turbine blades, hot-section engine parts, and high-performance tooling inserts.

Proven Superalloy Composition for High-Stress Environments

K465 alloy features a complex composition with Ni as the base, reinforced by Cr, Al, Ti, Mo, and W, along with trace elements such as B and Zr. This delivers:

• Excellent high-temperature strength and creep resistance

• Stable γ′ phase strengthening after heat treatment

• Long-term microstructural stability under thermal cycling

Its characteristics make it ideal for jet engines, gas turbines, and energy sector applications.

Outstanding Thermal Fatigue and Oxidation Resistance

K465 alloy powder resists:

• Oxidation and scaling at temperatures up to 1000–1100°C

• Thermal fatigue from frequent heating and cooling cycles

• Corrosive damage in harsh combustion environments

This leads to improved service life and lower maintenance in aero-engine and power generation systems.

Optimized for Additive Manufacturing

Produced via high-purity gas atomization, K465 alloy powder offers:

• High sphericity and flowability

• Controlled particle size distribution

• Compatibility with LPBF, EBM, and DED processes

The powder is suitable for fabricating near-net-shape components with minimal post-processing.

Application Scenarios

• Turbine blades and vanes

• High-temperature combustion chambers

• Hot-end components in aerospace engines

• Industrial gas turbine rotors

Key Advantages

• High mechanical strength above 900°C

• Excellent phase stability under stress and heat

• Good printability for advanced manufacturing

• Reliable performance in thermal fatigue conditions
