Casting is the first aluminum production processes. Extrusion: extrusion means profile is formed. The first product based on the profile section design, to create a mold using an extruder heated round good casting rod extrusion molding from the mold. Common grade 6063 alloy extrusion Shihai artificial aging process with an air-hardening process and subsequent to the completion of heat strengthened. Different grades can be heat strengthened alloy, different heat treatment system. 3, color (here mainly about the first oxidation process) oxide: extruded aluminum profiles good, the surface corrosion resistance is not strong Shandong aluminum surface treatment, surface treatment to be carried out by anodic oxidation of aluminum to increase aesthetics corrosion resistance, abrasion resistance and appearance. Case market feedback, the 28th along with futures market prices, Shanghai aluminum pipe distributors heart emboldened enhanced, but the lack of an active spot sales, traders think the price is difficult to put into practice. Lower demand in general, part of the business and because of supply specifications arrhythmia difficult to ship, it is expected on the 29th early mainstream market prices continue to consolidate. Domestic aluminum tube shelf pressure is not, but with the rise of the yield of aluminum surface treatment professional manufacturers, is increasing pressure on the stock, while exports will occur because of the summer holidays abroad shrinking Shandong surface oxidation aluminum manufacturers, After August, the spot heating supply pressure; furthermore market near the end of the financial pressure tight aluminum surface treatment, do not rule out some businesses for capital returns and accelerate sales. In addition, the traditional off-season led to lower demand, although some tight specifications resource price strong, but supply increased supplement once price competition will induce businesses Shandong surface treatment of aluminum _ _ surface treatment of aluminum rolls aluminum aluminum from Jinan Heshun Co.
