Aluminium is a versatile metal used in various applications, including construction, aerospace, and transportation. Two of the most popular types of aluminium are 6060 and 2007. Both have distinctive features and benefits that make them ideal for specific applications. If you’re curious about the differences between these two grades of aluminium, then you’re in the right place. This blog post will explore the major differences between Aluminium 6060 and 2007.
Difference Between Aluminium 6060 and 2007
Chemical Composition
Aluminium 6060 is a heat-treatable alloy with magnesium and silicon as its primary alloying elements. It is known for its excellent weldability, machinability, and corrosion resistance. On the other hand, Aluminium 2007 is a high-strength alloy specifically designed for mechanical applications. It has copper as its primary alloying element, which gives it improved resistance to corrosion and wear.
Physical Properties
Aluminium 6060 has a 2700 kg/m3 density and a melting point of 585°C. It has a high thermal conductivity and can easily form complex shapes. Aluminium 2007, on the other hand, has a density of 2830 kg/m3 and a melting point of 548°C. It has a slightly lower thermal conductivity than 6060 but is known for its excellent machinability and fatigue resistance.
Applications
Aluminium 6060 is commonly used in architectural and general engineering applications. Its excellent weldability and corrosion resistance make it ideal for use in structural frameworks, partitions, and windows. Aluminium 2007, on the other hand, is used in high-stress applications where strength and durability are critical. It is commonly found in aircraft extrusions, hydraulic components, and heavy-duty machinery.
Surface Finish
Aluminium 6060 and 2007 have different surface finishes. 6060 has a smooth surface that is suitable for anodising or painting. Its natural finish is bright but can be coated with powder or liquid paint. Aluminium 2007 has a rougher surface due to its high copper content, which makes it less suitable for anodising. The surface can be machined, polished, or coated with a protective layer to improve its appearance and durability.
Cost
Aluminium 6060 and 2007 costs may vary depending on the manufacturer, size, and quantity purchased. Generally, Aluminium 6060 is more affordable than Aluminium 2007 due to its lower copper content. However, the cost may increase for customised shapes, finishes, or larger quantities.
Conclusion:
In conclusion, Aluminium 6060 and 2007 are two popular aluminium grades with different features and benefits. Aluminium 6060 is ideal for architectural and general engineering applications, while Aluminium 2007 is best suited for mechanical applications that require high strength and durability. Both grades have distinctive properties that make them suitable for specific purposes. Understanding the differences between these two grades of aluminium can help you make an informed choice when selecting the right material for your project.
