Copper/Titanium Cu90/Ti10 - Powder - Material Information

Copper/Titanium (Cu90/Ti10) powder alloy is a high-strength, thermally stable material designed for use in advanced metallurgical, electrical, and structural applications. With its unique balance of conductivity and mechanical resilience, this alloy is a preferred choice for powder metallurgy processes that demand uniformity, high density, and performance reliability.

Material Overview

Composed of 90 % copper and 10 % titanium, Cu90/Ti10 powder exhibits a refined two-phase microstructure consisting of α-Cu and Cu4Ti precipitates. Titanium serves as both a solid-solution and precipitation-strengthening agent, enhancing mechanical hardness and wear resistance without significantly compromising electrical conductivity. When produced via mechanical alloying and sintering, Cu–Ti powders achieve high densification levels (>96 % of theoretical density) and fine grain structures that improve load-bearing capability and fatigue resistance (Eze et al., 2018). The alloy typically retains electrical conductivity between 60–70 % IACS, with compressive strengths surpassing 700 MPa due to Ti diffusion strengthening (Pripanapong & Luangvaranunt, 2010).

Applications and Advantages

Cu90/Ti10 powder alloys are ideal for producing high-performance parts such as electrical contacts, resistance welding electrodes, and aerospace components. Titanium improves oxidation resistance, making the alloy suitable for elevated-temperature environments and reducing surface degradation in reactive atmospheres. The powder form allows for versatile manufacturing techniques—including spark plasma sintering (SPS) and hot pressing—offering precise control over porosity and grain refinement (Şap, 2021). Mechanical alloying also promotes homogeneous element distribution, leading to superior bonding between copper and titanium particles. These characteristics enable the production of components that exhibit excellent wear resistance, dimensional stability, and consistent conductivity even under mechanical and thermal stress.
