Mirror aluminum sheet refers to the aluminum plate treated by rolling, grinding and other methods to make the surface of the plate appear mirror effect.
Classification of Mirror Aluminum Sheet
According to different surface treatment, mirror aluminum plate can be divided into common alloys mirror aluminum sheet coil ,embossed mirror aluminum sheet coil, anodized mirror aluminum, color coated mirror aluminum, etc.
According to the production method, there are common coated mirror aluminum plate, oxidized mirror aluminum plate, polished mirror aluminum plate and super mirror aluminum plate.
Technological Process of Mirror Aluminum Sheet
Hot rolling process: raw materials → melting → casting → extrusion → Heat treatment → straightening → cutting → inspection of finished products into storage. After oil removal and impurity removal, the melting charge is heated in the melting chamber to 1250 ~ 1350°C for 2 hours of degreasing treatment, and then sent to the crystallizer for cooling to 700 ~ 750°C for recrystallization treatment, and then cooled to 500 ~ 600°C by the water cooling system, and heated to 850 ~ 900°C or more for 1 hour of heat preservation and aging treatment High quality alloy ingot blanks can be obtained.
Cold drawing process: raw materials → hot forging die forming → cold drawing die forming + annealing + pickling → finished product storage.
Applications of Mirror Aluminum Sheet
Mirror aluminum is widely used in lighting reflectors and lighting decoration, solar heat collection reflective materials, interior building decoration, exterior wall decoration, household appliance panels, electronic products shell, furniture kitchen, automotive interior and exterior decoration, signs, signs, bags, jewelry boxes and other fields.
