Aluminum Alloys & Surface Finishes
HDC offers a wide range of aluminum alloys and surface finishes to satisfy different project requirements
Aluminum Alloy 2024 (AlCu4Mg1)
2024 is a high-strength alloy with the advantage of having high fatigue strength.
Its main alloying elements are copper and a small amount of magnesium. The processing performance is acceptable, but not as good as 6061. The disadvantage of 2024 is that the corrosion resistance is very poor, so the coating protection is usually required. T3 and T4 are common tempers for 2024.
2024 is primarily used in aircraft structural parts, rivets, truck wheels, and other applications that require high strength and good fatigue properties. CNC machining is commonly used to manufacture prototypes, low-volume parts, or repair parts.
Aluminum 2024 Properties
| Densidad (g/cm³) | Hardness (HB) | Resistencia a la fluencia (MPa) |
|---|---|---|
| 2.78 | 120 | 345 |
Aluminum Alloy 5052 (AlMg2.5)
The main alloying element of 5052 is magnesium, which has medium strength but excellent corrosion resistance, good formability (bending, stamping) and weldability. H32 is its usual state.
It is mainly used for parts that require excellent corrosion resistance, such as ship parts. When strength and hardness are not primary considerations, and corrosion resistance is key, 5052 is an excellent choice.
Aluminum 5052 Properties
| Densidad (g/cm³) | Hardness (HB) | Resistencia a la fluencia (MPa) |
|---|---|---|
| 2.68 | 60 | 193 |
Aluminum Alloy 6061 (AlMg1SiCu)
6061 is the most used aluminum alloy, mainly composed of magnesium and silicon. It has good strength, weldability, and corrosion resistance, excellent processing performance.
Typically, the T6 state (solution heat treatment + artificial aging) is used to obtain the best overall performance.
It is widely used in various structural parts, brackets, shells, auto parts, bicycle parts, consumer electronics parts, etc. Ideal for applications that require good overall performance and processability.
Propiedades del aluminio 6061
| Densidad (g/cm³) | Hardness (HB) | Resistencia a la fluencia (MPa) |
|---|---|---|
| 2.7 | 95 | 276 |
Aluminum Alloy 6063 (AlMg0.7Si)
6063 is part of the same 6000 series as 6061, but slightly less powerful than 6061. Its main alloying elements are the same as 6061, but the content is lower than that. T5 and T6 are its commonly used states.
6063 has excellent extrusion properties and is mainly used for extrusion profiles (door and window frames, radiators, etc.). CNC machining is often used to perform secondary processing on extruded profiles to manufacture final parts.
Aluminum 6063 Properties
| Densidad (g/cm³) | Hardness (HB) | Resistencia a la fluencia (MPa) |
|---|---|---|
| 2.7 | 73 | 214 |
Aluminum Alloy 6262
6262 is an alloy specially designed to improve cutting performance, on the basis of maintaining good strength and corrosion resistance, elements such as lead and bismuth are added, so that its cutting performance is very good. T6, T651, T9 are its commonly used tempers.
It is especially suitable for parts that require high-volume, high-efficiency, high-quality machining, such as hydraulic valve blocks, connectors, threaded parts, and parts that require complex contours and fine details.
Aluminum 6062 Properties
| Densidad (g/cm³) | Hardness (HB) | Resistencia a la fluencia (MPa) |
|---|---|---|
| 2.7 | 95 | 276 |
Aluminum Alloy 7075 (AlZn5.5MgCu)
7075 is an ultra-high-strength aluminum alloy, the main alloying elements are zinc, magnesium, and copper.
The strength of 7075 is more than 2 times that of 6000 series alloys, close to some steels, with T6 being the most commonly used high-strength temper. It has high hardness and good wear resistance, but the processing performance is not as good as 6061, and the corrosion resistance is poor.
7075 is commonly used in applications where strength is the primary consideration for aerospace structural parts (e.g., aircraft frames) and high-performance bicycle parts (frames, forks).
Propiedades del aluminio 7075
| Densidad (g/cm³) | Hardness (HB) | Resistencia a la fluencia (MPa) |
|---|---|---|
| 2.81 | 150 | 503 |

Benefits of CNC Aluminum
Aluminum alloy is widely used in CNC machining due to its lightweight nature, excellent machinability, and favorable strength-to-weight ratio.
These materials deliver high dimensional stability during cutting, resist tool wear, and enable complex geometries with tight tolerances.
Their natural corrosion resistance and compatibility with surface treatments (e.g., anodizing) further expand design possibilities across industries.
