6005 Aluminum: the best choice for solar installation structures

When it comes to choosing the right aluminum alloy for your project, it’s essential to understand the differences between commonly used alloys like 6063, 6061, and 6005.  Here’s a breakdown of each alloy and their suitability for solar structures:

6063 Aluminum Alloy:
6063 is a widely used extrusion alloy, known for its excellent formability and surface finish. It contains magnesium and silicon as alloying elements, making it highly resistant to corrosion and offering good mechanical properties. 6063 is often used in architectural applications due to its aesthetic appeal and ease of fabrication. It’s also suitable for lightweight structures due to its moderate strength.

6061 Aluminum Alloy:
6061 is a high-strength alloy widely used in structural applications, such as aerospace components, marine fittings, and automotive parts. It offers excellent machinability and weldability, making it a preferred choice for a range of industries.

6005 Aluminum Alloy:
6005 is a versatile alloy known for its excellent weldability and formability which is similar to 6063 but with higher mechanical properties. It contains magnesium and silicon as primary alloying elements, providing good formability, strength, and corrosion resistance. 6005 is often chosen for applications requiring higher strength than 6063, such as structural components in transportation, construction, and solar panel mounting systems.

The best choice among these alloys for solar installation structures depends on the strength and corrosion resistance.

Strength Requirements:
If the structure requires high strength to withstand wind loads, snow loads, or other environmental factors, 6061 or 6005 would be more suitable due to their higher mechanical properties compared to 6063.

Corrosion Resistance:
If the installation is in a corrosive environment, such as coastal areas with salt exposure, 6063 might be preferable due to its superior corrosion resistance. However, 6005 also offers good corrosion resistance and higher strength than 6063, making it a viable option for many solar installations.

In conclusion, while all three aluminum alloys have their advantages, 6005 may be the best choice for solar installation structures requiring a balance of strength, corrosion resistance.Since 2012, Solaracks has consistently utilized 6005 T5 aluminum for solar mounting kits and achieved a remarkable shipment of 350MW in 2023. Solaracks is renowned for providing comprehensive services to EPCs (Engineering, Procurement, and Construction companies) and has earned high praise and trust within the industry.
