The heat treatment of 6061 aluminum alloy can strengthen the alloy, with good formability, weldability, mechanical properties, at the same time with moderate strength, after annealing can still maintain good operability.
Using aluminum extrusion machine for aluminum in the residual air pressure, lead to appear the appearance and internal aluminum bubble, happen not completely solve the defect of the makes aluminum became a waste. In order to prevent air from entering the aluminum profile, it is important to find out the reason why air is brought in. The main factors of residual air in extruded aluminum profiles include:
Mass media, social networks, advertising is around everywhere. Advertising frame changing is much more common in the office, in the mall, in the exhibition hall, in the subway, at the airport and so everywhere.
The inferior aluminum profiles is easy to deform when affecting by sunlight, air, rain, etc., which has great security risk in daily life. Let’s see what characteristics that inferior aluminum profiles have.
After the chemical or electrochemical polishing, then the anodizing treatment, the aluminum products will obtain a smooth and bright layer of oxide film, with a high transparency, at this time, the aluminum alloy surface is easy to obtain various colors by dyeing. In the field of industry, the anodizing treatment or chemical oxidation methods are becoming more and more widely used, it makes aluminum alloys to obtain a layer of oxide film, and to achieve a purpose of protection and decoration.
