The purity of aluminium affects the surface effect of mirror aluminium. The difference of 0.1% will have a great influence on the brightness and clarity of the surface. The Mirror aluminum coil sheet for solar energy application thickness can be precisely controlled between 0.15 mm and 0.8 mm by high precision rolling mill.
We choose 1080 high purity aluminium base to ensure that the purity of aluminium is over 99.8%, the mirror reflectivity is over 85%, and the clarity is over 94%. The use of mirror aluminum coil sheet for solar energy application determines that it must have good easy-to-form properties. The mirror aluminium produced by us is in a semi-hard state suitable for bending, which ensures that users can process and shape later. The smoothness of mirror aluminum coil sheet for solar energy application is also an important factor affecting the imaging. We use the stretch bending straightener made in Germany, and the surface smoothness of aluminium sheet is close to 100%.
