mirror like finish aluminum
With the technological innovation of aluminum processing industry, the surface brightness and color of aluminum plate products have been rapidly improved. The mirror aluminum has emerged as a result, and gradually entered people's vision, and has been applied in lighting equipment, high-end cosmetics, automobile or interior and exterior wall of building. In recent years, the field of solar equipment and high-power LED lighting has developed rapidly, and the demand for reflective materials has also shown a rapid growth trend. Mirror like finish aluminum, as a new type of reflective material, is also being paid attention by all parties, and has become a major innovation field of aluminum application.
Mirror like finish aluminum is an aluminum plate product produced by rolling method. The surface can reach the effect of mirror. Even if the oxide film and coating produced by anodizing are added, it can still maintain high smoothness and high reflectivity, and maintain high scratch resistance, corrosion resistance, good strength and forming performance. At present, the common mirror aluminum is generally 1xxx, 3xxx, 8xxx. It is enough for ordinary decoration and other fields, but it is difficult to meet the requirements of high performance reflective materials. Therefore, the mirror aluminum as reflective material needs to develop towards higher reflectivity (full reflectance >90%), high thermal conductivity, high scratch resistance, corrosion resistance and medium strength.
In order to meet higher requirements of mirror aluminum, signi aluminum and Chalco aluminum cooperate with each other to realize the closed-loop research and development of mirror aluminum products through market orientation, laboratory research and industrial trial production, and developed high purity medium strength mirror aluminum of 5xxx system to meet the high requirements of LED lighting and solar industry. At present, the company has begun to expand the market for the application fields of solar energy, high-power LED lighting and gradually replace imported products.
It is reported that the strength mirror like finish aluminum of the 5xxx system is generally produced by rolling process, and the reflectivity is usually 90% or 95%, so the purity and surface state of the material are required to be very high. In the process of producing the product, aluminum processing enterprises need to strictly control the grain size and distribution uniformity of the second phase through adjusting the composition and technology to meet the final product requirements.
