(1) aluminum category Aluminum metal belonging to one category of non-ferrous metals, due to the application of a broader, separate presentation is as follows: common are aluminum and aluminum alloy die-casting two. Mainly by the purity is as high as 92% of aluminum ingots as the main raw materials, the addition of increased strength, hardness, wear resistance and other properties of metal elements, such as carbon, magnesium, silicon, sulfur and so on, the composition of a variety of ingredients "alloy." 1.1 Aluminum Aluminum common, such as screens, windows and so on. It is the use of extrusion process, namely, aluminum ingots and other raw materials in the melting furnace after extrusion extruder to die out of shape, it can be squeezed out of different cross-section profiles. Performance that is the main strength, hardness, wear resistance according to the national standard GB6063. The advantages are: light weight only 2.8, do not rust, design changes quickly, mold into a low, vertical elongation up to 10 meters. Aluminum appearance bright, matte division, and its treatment process using anodic oxidation treatment, surface treatment of the oxide film reached 0.12m / m thickness. Aluminum wall thickness depending on product design optimization to choose, rather than thicker, the better the market, should look at the requirements section of the structure design, it can be 0.5 ~ 5mm uneven. Layman that the thicker the more hard-line, in fact, is the erroneous point of view. Aluminum surface quality is also more difficult to overcome shortcomings: warpage, deformation, black line, convexity and white lines. And designers with high levels of mold design and production processes reasonable, can not be clear to avoid these deficiencies. Defect inspection testing methods should be state regulations, namely 40 ~ 50CM horizon to determine deficiencies. Aluminum furniture in a wide range of uses: screen frame, all kinds of hoisting beams, table legs of the table, decorative articles, handle and take the trunking and cover, chair control, etc., may be changing the design and use! Although the advantages of aluminum, but there is not an ideal place: Without oxidation of aluminum easy "rusty" resulting in decreased performance, vertical intensity than iron. Surface oxide layer wear resistance than plating scratches easily. Costs are relatively high, relatively high cost of iron products a 3 ~ 4 times. 1.2 Aluminum Alloy Die Casting Die-casting alloys and material processing methods, the use of equipment are different, and its raw materials to aluminum ingots (about 92% purity) and alloy materials, by a furnace to melt into the die-casting machine in the mold forming. Aluminum die-casting products can be designed to image the shape of toys, as different shapes to facilitate connectivity in all directions, while its hardness higher intensity, as well as mixed into zinc and zinc alloy.
