Aluminum 2017A is a high-strength, heat-treatable aluminum alloy in the Al-Cu-Mg series, known for its excellent mechanical properties and good machinability. It exhibits high tensile strength and hardness after heat treatment, making it suitable for structural and load-bearing components. Its moderate corrosion resistance is enhanced with protective coatings or anodizing. Common applications include aerospace components, automotive parts, precision machinery, and tooling where strength-to-weight ratio is critical. The alloy is often chosen for CNC machining and structural applications requiring reliable performance under stress.
