2024 aluminum-copper-magnesium hard alloy powder
2024 alloy is a quintessential hard aluminum alloy in the Al–Cu–Mg system, with a well‑balanced composition and excellent overall performance, making it the most widely used among hard aluminum alloys. Copper (3.8–4.9%) serves as the primary strengthening element, complemented by magnesium (1.2–1.8%) and manganese (0.3–0.9%) for synergistic reinforcement. After solution treatment and aging, its tensile strength can reach 400–470 MPa, comparable to that of medium‑carbon steel. This alloy exhibits high strength and moderate heat resistance, suitable for service components operating below 150°C; at temperatures above 125°C, its strength even surpasses that of 7075 alloy. TIJO employs an inert‑gas atomization process to produce spherical 2024 powder, with oxygen content ≤500 ppm, excellent sphericity, and superior flowability. It is ideal for additive manufacturing processes such as SLM/LPBF, powder metallurgy compaction, and cold spraying. Applications include aircraft skin panels, wing spars, and bulkheads, truck wheels, high‑load gears, missile components, and riveted structural parts. Note: 2024 has relatively poor corrosion resistance and limited weldability (prone to cracking); therefore, riveted joints are recommended, coupled with anodizing or aluminum cladding for protection.
It exhibits poor corrosion resistance; anodizing or aluminum cladding is recommended. Its weldability is poor, so riveted joints are advised.
