How CuNiAlTi Delivers Strength and Stability for Thermal and Electrical Applications

CuNiAlTi is a precipitation-strengthened copper-based material combining copper (Cu), nickel (Ni), aluminum (Al), and titanium (Ti). This composition delivers a unique combination of high strength, corrosion resistance, and moderate electrical conductivity, making it suitable for thermal, electrical, and structural uses in aerospace, electronics, and marine environments.

High Strength with Reliable Conductivity

CuNiAlTi exhibits:

• Enhanced tensile and yield strength through fine precipitate hardening

• Retention of moderate electrical and thermal conductivity

• Excellent dimensional stability under mechanical or thermal stress

This makes it ideal for applications requiring a balance of strength and conductivity, such as contact springs, connectors, and high-load bushings.

Corrosion and Fatigue Resistance

With the addition of nickel and aluminum, CuNiAlTi achieves:

• Strong resistance to corrosion in saltwater and oxidizing environments

• Superior fatigue life in dynamic or cyclic loading conditions

• Minimal performance degradation over long service periods

Processability for Advanced Manufacturing

CuNiAlTi powder or ingots can be used in:

• Additive manufacturing via selective laser melting (SLM) or DED

• Metal injection molding (MIM) or conventional forging

• Heat treatment for tuning strength–ductility balance

Application Areas

• Aerospace thermal and electrical connectors

• High-load sliding components and bearings

• Marine fasteners and anti-corrosive parts

• Electronic spring contacts with mechanical stress tolerance

Benefits Summary

• High strength-to-conductivity ratio

• Outstanding corrosion and fatigue resistance

• Excellent thermal stability and machinability

• Suitable for AM, MIM, forging, and thermal processing
