Copper/Titanium alloy (Cu90/Ti10) represents a unique class of high-performance materials that combine the superior electrical and thermal conductivity of copper with the high strength and corrosion resistance imparted by titanium. This alloy, often produced via powder metallurgy, offers an excellent balance of mechanical performance and conductivity for advanced industrial and electronic applications.
Material Overview
Cu90/Ti10 alloys contain approximately 90 % copper and 10 % titanium, forming a two-phase microstructure consisting of α-Cu and Cu4Ti intermetallic compounds. Titanium acts as a solid-solution and precipitation-strengthening agent, significantly enhancing hardness and wear resistance. Studies on powder-metallurgical Cu–Ti systems show that increasing Ti content promotes the formation of fine intermetallic layers that reinforce mechanical integrity (Karakulak, 2017). The resulting materials exhibit hardness up to 200 HV and tensile strengths above 600 MPa while maintaining electrical conductivities around 60–70 % IACS. Mechanical alloying and hot pressing further refine the grain structure and improve bonding between particles, leading to superior densification and mechanical performance (Tang et al., 1997).
Applications and Advantages
Cu90/Ti10 alloys are widely utilized in electrical connectors, resistance welding electrodes, and high-temperature components requiring a combination of strength and conductivity. Titanium’s addition enhances corrosion resistance, particularly against chlorides and oxidizing environments, making it suitable for marine and aerospace systems (Arkusz et al., 2024). In powder form, the alloy can be consolidated into complex geometries while maintaining uniform composition. The use of powder metallurgy also allows for fine control of intermetallic formation, optimizing both mechanical and electrical behavior. These properties make Cu–Ti alloys attractive for next-generation electronic packaging, conductive springs, and energy systems where high reliability is essential.
