2024 Aluminum Alloy
2024 aluminum alloy is a high-strength, heat-treatable material with copper as its primary alloying element. Known for its excellent strength-to-weight ratio, it is widely used in aerospace and high-performance engineering. In its annealed state, 2024 is highly malleable and can be easily formed before undergoing heat treatment to achieve structural-grade strength.
This alloy is ideal for components where weight savings and fatigue resistance are critical. Its balanced composition and mechanical performance make it a top choice in aerospace, automotive, and sporting goods manufacturing.
