Published by HUAXIAO TECH manufacturer

In high-performance industries like aerospace and defense, selecting the right alloy powder is crucial. 18Ni15Co6.7Mo2Ti alloy powder offers exceptional mechanical properties, making it a leading choice for additive manufacturing and metal injection molding of critical components.

Exceptional Strength-to-Weight Ratio

18Ni15Co6.7Mo2Ti is a maraging steel-based alloy featuring 18% Ni, 15% Co, 6.7% Mo, and 2% Ti. This balanced composition allows it to deliver:

• Ultra-high tensile strength after heat treatment

• Low carbon content, improving weldability and processing

• Excellent ductility, preventing fractures during high-stress usage

These properties make it ideal for complex, load-bearing parts in aircraft and missiles.

Superior Heat and Fatigue Resistance

Thanks to its aging-hardening behavior, this alloy resists:

• Thermal creep and fatigue in high-temperature applications

• Microstructural instability, maintaining performance under cyclical stress

• Dimensional distortion, ideal for precision tooling

This makes it highly suitable for jet engine components, landing gears, and tooling inserts.

Perfect for Additive Manufacturing & MIM

The spherical morphology and uniform particle size of this powder ensure:

• Excellent flowability and packing density

• Uniform melting behavior in laser sintering and EBM

• Reliable results for powder bed fusion and metal injection molding (MIM)

Application Scenarios

• Aerospace structural frames

• Jet engine housings and blades

• High-precision injection molds

• Defense and rocket parts

Benefits Summary

• High mechanical strength after aging treatment

• Thermal stability for high-temperature use

• Good printability and sinterability in 3D printing

• Dimensional accuracy and corrosion resistance

Frequently Asked Questions (FAQ)

Q1: What heat treatment is required?
