What kind of aluminum do you choose and what need to be paid attention to in the process of manufacturing aluminium alloy doors and windows?
The first factor is Materials First of all, materials used by high-class aluminium alloy doors and windows, such as thickness, intensity and oxidation film, should comply with the regulations of the relevant national standards. The wall thickness should be above 1.2 millimeters. Tensile strength need to reach 157 newtons per square millimeter. Yield strength should … Continued
Aluminum Oxide Film Formation Reason
When sulfate solution is in the process of oxidation, you can find that aluminum ion content is adding in the solution area near the anode. At the moment, oxygen is separated from it, and it is composed of oxide film. However, hydrogen is separated on cathode. The composition of oxide film reflects that two processes … Continued
The Definition of Aluminum Profile Extrusion Ratio
Aluminum extrusion ratio calculation formula is used for expressing aluminum alloy deformation size parameters in the production of aluminum extrusion profile, namely extrusion coefficient. That is products’ total cross sectional area before extrusion (unit mm2) divides products’ total cross sectional area after extrusion (unit mm2). Therefore, extrusion ratio and the deformation degree have the following … Continued
How to Discern Quality of Architectural Aluminum Profile
Here are some tips for you to discern the quality of the architectural aluminum profile. 1. Check the factory quality certificate, pay attention to the date of production, specifications, technical conditions, enterprise name, and the production license number. 2. It is important to note that the wall thickness of the aluminum profile product. The thickness … Continued
Chemical Conversion Treatment of Aluminum and Aluminum Profile
Chemical conversion of aluminum and aluminum profile surface is made of aluminum and chemical oxidant solution constituted a direct response, the applied voltage without going through this process, known as chemical oxidation disposal. The nature of its chemical conversion solution can be divided into two major categories of basic and acidic, but its nature but … Continued
Aluminum Balcony Sliding Door Classification

Therefore, buy balcony door not only to understand his design style, product design. Also need to clearly understand that in accordance with … Continued
Five Kinds of Different Solutions of Low Zinc Coating Binding Force
There are plenty of factors of low zinc coating binding force, but the following five kinds of situations are relatively seen by people. (1) Add too much additive. The brightness of zincate galvanized layer is less than potassium chloride galvanized layer. Some people think that adding more brightener can enhance brightness. As a result, this … Continued
The Surface Treatment of Aluminum Ceiling
The surface treatment of aluminum ceiling is coating, roller coating, and anodic oxidation. The several technical methods and advantages of the implementation are not identical respectively. Coating is kinds of physical technology, forming by pressing a layer of film and a layer of aluminum plate after high temperature and high pressure. Roller coating is to … Continued
