In the evolving landscape of high-performance metallurgy, C18150 (Chromium Zirconium Copper) has emerged as the cornerstone for industries requiring an uncompromising balance between thermal stability and electrical conductivity. Unlike traditional copper, C18150 is engineered through precipitation hardening, allowing it to maintain its mechanical properties at extreme temperatures that would typically soften high-purity copper.
As a leading OEM factory, Sichuan Kepai New Materials Co., Ltd. leverages its proprietary R&D to provide C18150 solutions that exceed standard industry benchmarks. This white paper explores the mechanical depths of this alloy and its pivotal role in the global transition toward sustainable electrification and aerospace precision.
The addition of Chromium (0.5-1.5%) and Zirconium (0.05-0.25%) allows for a tensile strength ranging from 450 to 550 MPa, essential for components under heavy structural load.
C18150 maintains its hardness up to 500°C, making it the preferred material for resistance welding electrodes where heat accumulation is unavoidable.
With an electrical conductivity of >80% IACS, it facilitates energy-efficient power transmission in EV charging systems and high-current connectors.
The refined grain structure produced by our factory’s heat treatment processes ensures high cycle fatigue life, critical for aerospace applications.
