Chalco Aluminum 6005,6063A,6463,6R63 6060,6063 6061 Aluminum alloy profiles can be typically used for the frameworks of solar cells.
These aluminum alloys 6005,6063A,6463,6R63 6060,6063 6061 are belong to 6xxx SeriesMagnesium & Silicon alloy,are the most popular extrusion alloy class. With Good strength.good extrudability, good strength,good corrosion resistance,good machinability,good weldability.good formability.and heat treatable,etc characteristics.And can be easily anodised,therefore, the surface can be divided into Anodizing surface and Electrophoretic coating surface.
