Why CuTi Alloy Powder Is Ideal for Antibacterial and Wear-Resistant Applications

Published by HUAXIAO TECH manufacturer

CuTi alloy powder combines the excellent electrical and thermal conductivity of copper with the enhanced strength, corrosion resistance, and antibacterial properties brought by titanium. This unique combination makes it a high-performance powder for various advanced applications.

Enhanced Mechanical Properties with Titanium Addition

Copper is well-known for its conductivity but lacks strength. The introduction of titanium forms fine intermetallic compounds that improve:

• Hardness and tensile strength

• Thermal fatigue resistance

• Microstructural stability under load

These improvements make CuTi powder suitable for functional parts requiring durability and performance.

Excellent Antibacterial Activity

CuTi alloys exhibit strong antibacterial performance, particularly against E. coli and S. aureus. This makes the powder suitable for:

• Medical instruments

• Public-touch surfaces

• Food-grade processing components

The alloy releases Cu⁺ ions that disrupt bacterial cell membranes while maintaining surface durability over time.

Ideal for Additive Manufacturing and Coating

With its spherical shape and controlled particle size, CuTi powder ensures:

• Good flowability for laser powder bed fusion (LPBF) and direct energy deposition (DED)

• High-density coatings with excellent adhesion

• Compatibility with cold spray and plasma spray technologies

Application Scenarios

• Medical device housings and dental tools

• High-touch hardware in hospitals or public transport

• Heat exchangers and electrical connectors with wear resistance

• Aerospace or marine components needing corrosion protection

Benefits Summary

• High strength-to-weight ratio

• Outstanding wear and corrosion resistance

• Natural antibacterial effect without coatings

• Excellent 3D printing and thermal spray compatibility
