Why Use Aluminum Alloy For Decorative Lines？

Aluminum alloy decorative lines, which are made of aluminum alloy as the base material, are part of aluminum profiles.
Step 1 Be light
The low density of pure aluminum, about one-third that of iron, and its light weight and ease of handling and handling are among the reasons for its popularity.
2. Abundant resources
Aluminum is the most abundant metal element in the Earth's crust, ranking third after oxygen and silicon. And aluminum has a very high recyclability, the characteristics of recycled aluminum and the original aluminum almost no difference.
3. High plasticity
Aluminum is face-centered cubic structure, so it has high plasticity, easy to process, can be made into a variety of profiles, plates.
4. Corrosion resistance
Aluminum corrosion resistance is very good, 100% waterproof and insect resistant, with its raw materials made of products long service life.
But the strength of pure aluminum is not high, so people to add alloying elements (such as: silicon (Si), copper (Cu), magnesium (Mg), iron (Fe)) and the use of heat treatment methods to strengthen aluminum, and improve the pure aluminum in casting, chemical and physical properties of these three aspects of the deficiency. Aluminum alloy in the maintenance of pure aluminum light and other advantages at the same time can have a high strength, so that its "strength" is better than a lot of alloy steel, become an ideal structural material, is widely used, also become an important material of decorative lines.
Aluminum alloy decorative line processing technology
The production of aluminum alloy lines includes three processes: fusion casting, extrusion and oxidation surface treatment, the specific process is as follows: aluminum ingot - dissolution - alloy ratio - rod forming - extrusion forming - aging - surface treatment - cutting according to the specified size of the parts - finished products.
Generally speaking, manufacturers choose to directly purchase the processed aluminum alloy bar material (aluminum alloy commonly used for decorative lines is 6063), and then complete the production operations such as extrusion and surface treatment.
Extrusion process. First of all, the mold is designed and manufactured according to the cross-section shape of the line, and then the heated cast rod is extruded from the mold to form the profile of the line.
Surface treatment, extruded good aluminum alloy profiles through a variety of surface treatment, can get colorful appearance, but also can further strengthen the surface of the profiles wear resistance, corrosion resistance and other properties. There are a variety of surface treatment methods of aluminum profile, aluminum alloy decorative lines commonly used surface treatment methods are anodic oxidation (extrusion good aluminum profile, its surface corrosion resistance is not strong, must be through anodic oxidation surface treatment to increase the corrosion resistance of aluminum, wear resistance and appearance of beauty), wire drawing, frosting, heat transfer, paint, coated PVC film
