About Aluminum Furniture Profile
Aluminum belongs to one of the metal categories of non-ferrous metals, due to a wide range of applications, aluminum furniture profiles in the use of furniture is very wide: screen skeleton, a variety of hanging beams, table feet, decorative strips, handles, wiring grooves and covers, chair tubes and so on, can be ever-changing design and use!
There are two kinds of aluminum furniture profiles and die-casting aluminum alloys. Among them, the purity of up to 92% of aluminum ingots as the main raw materials, while adding increased strength, hardness, wear resistance and other properties of metal elements, such as carbon, magnesium, silicon, sulfur, etc., composed of a variety of components "alloy."
1.Aluminum furniture profiles: aluminum furniture profiles are common such as screens, aluminum windows and so on it is the use of extrusion molding process, that is, aluminum ingots and other raw materials in the furnace melting, after extruder extrusion to mold outflow molding, it can also squeeze out a variety of different sections of the profile. The main performance is strength, hardness, wear resistance are GB6063 according to national standards. Advantages: Light weight only 2.8, do not rust, design changes fast, mold input low, longitudinal elongation up to more than 10 meters. Aluminum profile appearance has bright, matte division, its treatment process using anodic oxidation treatment, surface treatment oxide film to reach 0.12m/m thickness. Aluminum furniture profiles wall thickness according to product design optimization to choose, not the thicker the better, should look at the cross-sectional structure requirements for design, it can be uneven in 0.5~5mm.Laymen think the thicker the tougher, in fact, is the wrong view.
2.Disadvantages of aluminum furniture profiles: warping, deformation, black line, concave and white lines. Designers of high level and mold design and production process is reasonable, can avoid the above defects are not too obvious. Inspection defects should be carried out according to national regulations, that is, visual distance 40~50CM to distinguish defects. Oxidation-treated aluminum is easy to "rust", resulting in reduced performance, longitudinal strength is not comparable to iron products. Surface oxidation layer wear resistance is not as easy to scrape as electroplating layer. The cost is higher.
