Aluminum Profiles: Aluminum profiles are common such as screens, aluminum windows and so it is the use of extrusion molding process, that is, aluminum ingots and other raw materials in the melting furnace, after extrusion extrusion machine to mold outflow molding, it can also extrude a variety of different sections of the profile. The main properties are strength, hardness, wear resistance according to national standards GB6063. Advantages: Light weight of only 2.8, not rust, design changes quickly, die input low, longitudinal elongation up to 10 meters. The appearance of aluminum profile has a bright, matte light, the treatment process using anodic oxidation treatment, surface treatment of 0 oxide film. 12m M thickness. Aluminum wall thickness According to product design optimization to choose, not the market thicker the better, should look at the cross-section structure requirements for design, it can be in 0.5mm uneven. The layman thinks that the thicker the tougher, in fact, is the wrong view. Disadvantages: warping, deformation, black, convex and white lines. The designer and the mold design and production process are reasonable, which can avoid the above defects are not obvious. Inspection defects should be carried out according to the national regulations, that is, line-of-sight 40 to discriminate defects. Untreated aluminum is easy to "rust", resulting in reduced performance and longitudinal strength than iron products. Surface oxidation layer wear resistance is less than the plating layer easy to scrape. The cost is higher.
