How to choose Office furniture aluminium

&Nbsp;   aluminum in the metal category in one of the non-ferrous metals, due to the widely used, individually described below: two commonly used aluminum and die-cast aluminum alloy. Which is mainly composed of aluminum ingot purity above 92% as the main raw material, while adding increased performance elements such as strength, hardness, resistance to abrasion, such as carbon, Silicon, magnesium, sulfur, composed of a variety of components "alloy".
&Nbsp;   1.1 common as aluminum aluminum screens, aluminium Windows, showcase, etc. It is produced by extrusion molding process, namely in the furnace and melting of raw materials such as aluminum ingots after extruder extruding to die out, it can also be extruded profiles of the various sections. Main properties of strength, hardness, resistance to abrasion according to national standards GB6063. Advantages: light weight only 2.8, does not rust, design changes, die longitudinal elongation of low investment, up to 10 meters. Aluminum-look shiny, matte and its processing technology using Anodic oxidation processing, surface oxide film thickness of 0.12m/m. Aluminium wall thickness according to product design optimization to choose, not the thicker the better on the market should see section structure is designed, it can be uneven in 0.5~5mm. Layman thinks that the thicker the hawkish view is wrong.
&Nbsp;   surface quality of aluminium profiles are also more difficult to overcome the deficiencies: warping, distortion, black lines, concave and the white line. High level of designers and mold design and production process, avoids these defects not too obvious. Check the defect should be carried out according to the test methods prescribed by the State, the horizon 40~50CM to identify defects.
&Nbsp;   aluminum profiles in a wide range of uses in the furniture: screen skeleton, hanging beams, table legs, decorations, handles, Groove and covers, seat tube, and so on, can be ever-changing designs and use!
&Nbsp;   aluminum advantages, but there are not the ideal place:
&Nbsp;   without the oxidation of aluminium material easier to "rust" which result in performance degradation, longitudinal strength than iron products. surface oxide layer on wear resistance of electroplated coatings of less than easy to scratch. higher cost 3~4 times higher relative cost of iron products.
