Aluminum Alloy 2024 T3 T4 T351 Properties
1. Chemical Composition (%)
2024 aluminum alloy uses aluminum as the base, with precisely balanced copper, magnesium, and manganese content that ensures high mechanical performance.
| Element | Si | Fe | Cu | Mn | Mg | Cr | Zn | Ti | Others (each/total) | Al |
|---|---|---|---|---|---|---|---|---|---|---|
| Content (%) | ≤0.50 | ≤0.50 | 3.8–4.9 | 0.3–0.9 | 1.2–1.8 | ≤0.10 | ≤0.25 | ≤0.15 | 0.05/0.15 | Balance |
2.Mechanical Properties
| Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Hardness (HBW) | Fatigue Strength (MPa) |
|---|---|---|---|---|---|
| T3 | 420–450 | 270–310 | 6–8 | 120 | ≈140 (10⁷ cycles) |
| T4 | ≥420 | ≥270 | ≥10 | 120 | - |
| T351 | 420–450 | 270–310 | 6–8 | 120 | ≈140 |
Note: T3 involves solution heat treatment and cold working; T4 involves solution treatment and natural aging; T351 involves solution treatment with stress relief stretching (permanent deformation 1.5–3%).
3. Overall Characteristics
Strength advantage: Below 150°C, its strength surpasses 7075 alloy; its strength-to-weight ratio is nearly 50% that of steel.
Machinability: Excellent in hot forming and after quenching; supports precision milling and drilling (recommended cutting speed 200–300 m/min).
Limitation: Moderate corrosion resistance—requires cladding or surface treatment for enhanced protection.
