Al5CuNi4
metal· Al5CuNi4
Al5CuNi4 is a precipitation-hardened aluminum alloy combining copper and nickel additions to the aluminum matrix, designed to achieve enhanced strength and hardness through age-hardening treatment. This alloy belongs to the aluminum-copper-nickel family and is primarily used in aerospace and high-performance applications where elevated temperature strength and wear resistance are required, offering improved hardness and thermal stability compared to conventional Al-Cu alloys like 2024 or 2014.
