Note: Mechanical properties are typical values for coil form and may vary slightly depending on the specific grade (e.g., 2017, 2024) and temper (T3, T4, T6).
Typical Grades of 2000 Series Aluminum Coils
Common 2xxx series coil grades include 2A11, 2A06, 2017, and 2024 — each engineered with a balanced composition of aluminum and copper plus other strengthening elements. The representative 2024 aluminum alloy has the following typical chemical range:
| Element | Content (%) |
|---|---|
| Aluminum (Al) | Balance |
| Copper (Cu) | 3.8 – 4.9 |
| Magnesium (Mg) | 1.2 – 1.8 |
| Manganese (Mn) | 0.3 – 0.9 |
| Silicon (Si) | ≤ 0.50 |
| Iron (Fe) | ≤ 0.50 |
| Zinc (Zn) | ≤ 0.25 |
| Chromium (Cr) | ≤ 0.10 |
| Titanium (Ti) | ≤ 0.15 |
| Other elements (total) | ≤ 0.15 |
Technical Note:
The relatively high copper content (typically 3.0–5.0%, depending on grade) is the key factor responsible for the superior strength and age-hardening capability of 2xxx series aluminum alloys.
Production Process & Heat Treatment Characteristics
2000 series aluminum–copper alloy coils are heat-treatable alloys, primarily strengthened through solution heat treatment and artificial aging.
Available Tempers
-
O (Annealed): Soft condition, good formability
-
T3 / T4: Solution heat-treated and naturally aged
-
T6: Solution heat-treated and artificially aged for maximum strength
The T-temper condition significantly enhances tensile and yield strength, making these coils suitable for components subjected to high static loads and cyclic fatigue stresses.

Frequently Asked Questions
2000 Series alloys strengthen primarily through precipitation hardening (heat treatment). The addition of copper and optimized heat‑treatable tempers (such as T3, T4, T6) significantly increases tensile and yield strength compared with non‑heat‑treatable series.
Yes. 2000 Series aluminum–copper alloys are heat‑treatable, meaning they can be processed through solution heat treatment and aging to achieve enhanced mechanical strength and performance tailored to specific applications.
2000 Series aluminum–copper coils are typically manufactured to meet international standards such as GB/T 3880, EN 485, and ASTM B209, ensuring consistent quality, traceability, and global acceptance for aerospace or industrial use.
2000 Series coils can be supplied with a mill finish or prepared for additional surface treatments, such as anodizing, coating, or protective films, to meet architectural, industrial, or corrosion‑resistant requirements.
Welding of 2000 Series alloys can be challenging; some grades (like 2024) are weldable only by specific processes (e.g., friction welding) due to their high strength and composition. Care should be taken in design and fabrication.
