Pure Aluminum Round Tube

Features

Thermal conductivity

The thermal conductivity of aluminum alloy is about 50-60% of that of copper, which is beneficial to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, as well as automobile cylinder heads and radiators.

Non ferromagnetism

Aluminum profile is non ferromagnetic, which is an important characteristic for electrical industry and electronic industry. Aluminum profiles cannot spontaneously ignite, which is important for applications involving handling or contacting flammable and explosive materials.

Main Process of Coloring

(1) Surface pretreatment: clean the profile surface with chemical or physical methods to expose the pure matrix, so as to obtain a complete and dense artificial oxide film. A specular or matte surface can also be obtained by mechanical means.

(2) Anodizing: for the surface pretreated profile, under certain process conditions, the substrate surface will be anodized to form a layer of dense, porous and strong adsorption Al2O3 film.

(3) Hole sealing: seal the pores of the porous oxide film generated after anodic oxidation, so as to enhance the anti pollution, anti-corrosion and wear resistance of the oxide film. The oxide film is colorless and transparent. By using the strong adsorption of the oxide film before sealing the hole, some metal salts are adsorbed and deposited in the film hole, which can make the appearance of the profile show many colors other than the natural color (silver white), such as black, bronze, golden yellow and stainless steel.

Characteristics and properties of aluminum profiles after various surface treatment processes

Frosted fabric aluminum profile: frosted surface aluminum profile avoids the disadvantage that bright aluminum alloy profile will form light interference under certain environment and conditions in architectural decoration. Its surface is as delicate and soft as brocade, which is very favored by the market. However, the existing frosted material must overcome the uneven sand particles on the surface and see the deficiency of pattern pattern.

Multi tone surface treatment aluminum profiles: the monotonous silver white and tan color can no longer meet the good cooperation between architects and exterior wall decorative tiles and exterior wall latex. The new stainless steel color, champagne color, golden yellow, titanium gold, red series (wine red, jujube red, black, purple) and colored glass can add icing on the cake to the decorative effect. These profiles must be chemically or mechanically polished and then oxidized for good results.

Electrophoretic painted aluminum profiles: electrophoretic painted profiles have soft surface gloss and can resist the erosion of cement and mortar acid rain. 90% of aluminum profiles in Japan have been electrophoretic painted.

Powder electrostatic spraying aluminum profile: powder electrostatic spraying profile is characterized by excellent corrosion resistance, acid, alkali and salt spray resistance, which is much better than oxidation coloring profile.

Plasma enhanced electrochemical surface ceramic aluminum profile: this type of material is the most advanced treatment technology in the world. The product quality of this profile is excellent, but the cost is high. It has more than 20 colors. Its biggest feature is that it can be colored like printed cloth as needed. The surface of the profile is colorful and the decorative effect is excellent
