Solar panel frame material
It is well known that the solar panel frame is also called solar panel aluminum. So we can figure out that the frame is made of aluminum. But it is not of pure aluminum, cause the pure aluminum is too soft which can be deformed easily.
Now we use the aluminum alloy 6000 series material to make the solar frame for solar panel based on its high strength and firmness. Currently, we use 6063 and 6005 aluminum alloy material to produce solar frames.
Advantage of aluminum solar frame
1. Corrosion resistance and strong oxidation resistance;
2. Strong strength and firmness;
3. Strong tensile strength;
4. High elasticity, rigidity, and metal fatigue value;
5. Convenient transportation and installation, even if the surface is scratched, it will not oxidize, and does not affect performance;
6. It can adapt to various environments through a convenient selection of different materials;
7. The service life is more than 25 years.
Now let us have a deep understanding of aluminum frame material chemical composition and mechanical properties.
