Aluminum Material

(1) Aluminum materials belonging to the metal category of non-ferrous Metals, because of the wider application, a separate introduction as follows: There are commonly used aluminum and die-casting aluminum alloy two. Mainly by the purity of more than 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."

1.1 Aluminum 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 melting furnace, after extruding 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 are: Light weight of only 2.8, not rust, design changes quickly, mold 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. The surface quality of aluminum profiles is also difficult to overcome defects: 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. Aluminum profiles in the use of furniture is very wide: screen skeleton, a variety of hanging beams, table feet, decorative strips, handle, line groove and cover, chair tube and so on, can be ever-changing design and use! Although the aluminum profile has many advantages, but there is also an undesirable place: aluminum material without oxidation is easy to "rust", resulting in a decline in performance, the longitudinal strength is not comparable to iron products. Surface oxidation layer is not as easy to scrape as the plating layer. High cost, relative to the cost of iron products $number times.

1.2 Die-Casting aluminum alloy die-casting alloy and profile processing methods compared to the use of equipment are different, its raw materials to aluminum ingots (purity of about 92%) and alloy materials, melting furnace, into the die-casting machine mold forming. Die-casting aluminum product shape can be designed to imaging toys, different shapes, convenient connections in all directions, in addition, it has a higher hardness strength, and zinc can be mixed with zinc alloy. Die-Casting Aluminum Molding technology: 1, die-cast type 2, coarse polishing to die more than 3, fine polishing on the other hand, die-casting aluminum production process, the mold can be made, its mold cost is very expensive, than injection mold and other molds are high. At the same time, the mold maintenance is very difficult, design error is difficult to reduce material repair. Die-casting Aluminum disadvantage: each production and processing quantity should be much, the cost is low. Polishing is more complex than the production cycle of slow product costs than injection parts $number times. Screw hole requirements should be one points (diameter 4.5mm) Even relay to stabilize the scope of adaptation: Taiwan feet, connectors, decorative head, aluminum sealing parts, countertops and tea table tops, etc., a wide range.
