What kinds of aluminum alloy material are used in casting?
The surface quality of aluminum profile is also difficult to overcome: warping, deformation, black lines, concave convex and white lines. Designers with high levels and reasonable mold design and production process can avoid the defects are not obvious. Inspection defects shall be carried out in accordance with national inspection methods, that is, sight distance 40~50CM to discriminate defects.
Aluminum and aluminum as common screen etc.. It is used extrusion process, that is, aluminum ingots and other raw materials in the melting furnace, after extrusion extruder extrusion die molding, it can also extrude a variety of profiles of different sections. The main properties, namely strength, hardness and wear resistance, are in accordance with the national standard GB6063. The utility model has the advantages of light weight, only 2.8, no rust, fast design change, low die input and longitudinal elongation up to more than 10 meters. There is light, matte of aluminum appearance, the process of anodic oxidation treatment, surface treatment of oxide film thickness reaches 0.12m/m. The thickness of aluminium section according to product design optimization choice, the market is not as thick as possible, should look at the section structure requirements of the design, it can not in 0.5~5mm. Layman thinks that the thicker and tougher, it is the wrong view.
Aluminum profiles are widely used in furniture: screens, skeletons, various kinds of suspension beams, tables, feet, decorative strips, handles, winding grooves and covers, chairs, tubes and so on. They can be designed and used in a variety of ways!
