2024 aluminum is a high-strength aluminum-copper alloy used extensively in aerospace structures for applications requiring excellent fatigue resistance and damage tolerance at temperatures up to approximately 150°C. T3 temper (solution heat-treated and cold-worked) provides optimal strength-to-weight ratio and fracture toughness, making it the preferred condition for drawn tubing in aircraft fuselage skins, fastener holes, and other primary load-bearing components.
