6063 aluminum surface is easily scratched, scratches or bumps, mainly due to: 1, ingot or slab debris attached to the surface segregation. The presence of a large number of ingot surface thereof while floating segregation ingot was not conducted when the equalization process or the homogenization treatment is not effective 5083 aluminum alloy, ingot memory hard metal particles in a certain amount of metal flowing through during the extrusion process When working with a production of 5083 alloy aluminum factory in Jinan, the segregation or hard surfaced metal particles attached to the work surface or to work with a belt damage, eventually leading to scratches on the surface profile; 2, the mold cavity or working to bring a debris, mold work with low hardness make it work with a surface scratch injury during extrusion profiles; 3, the material put on the bed rail or have had a hard inclusions in the bare metal or graphite strip, when it and cause when you scratch the surface profile exposure profiles; 4, at the fork to feed lever profiles from the track when the material placed on the bed, caused due to excessive speed bumps profiles; 5, causing abrasions man posing in bed drag profiles ; 6, during transport or friction between the extruded profiles damage. According to different aluminum content of alloying elements can be divided into eight series were 1 *** 2 *** 3 *** 4 *** 5 *** 6 *** *** 7 8 *** 1-8 series aluminum uses introduction: 8 ××× series of aluminum plates 8 ××× series aluminum sheet: 8011 is more commonly used for the production of aluminum 5083 alloy aluminum sheet metal factory in Shandong, belong to other series. The main function is to make caps for aluminum, also used in radiators, most applications of aluminum foil. Is not commonly used in business series.
