Does the aluminum profile conduct electricity?
The aluminum profile itself is conductive, in the metal conductivity in the top 4, so his conductive performance is very good, some people will say, why are not the aluminum conductive?

Below is Pumay Aluminum Cindy's explanation for you. 

Anodic oxidation

Aluminum or aluminum alloy products as anodes, placed in the electrolyte solution for electrification treatment, the use of electrolysis so that it's the surface formation of the alumina film process, known as aluminum and aluminum alloy anodizing process. After anodic oxidation treatment, the surface of aluminum can be formed into several micrometers —— several hundred micrometers of an oxide film. Compared with the natural oxide film of aluminum alloy, its corrosion resistance, wear-resistance, and decorative properties have been significantly improved and improved.

Oxide film

Anodizing forms a dense oxide film on the surface of the aluminum profile. Because alumina is non-conductive, the aluminum profile coated with alumina becomes an insulator

Some people also ask here, doesn't aluminum form an oxide film naturally? Yes, aluminum does form an oxide film, but the thickness of the natural oxide film is very thin, not even enough, not artificially uniform, so it doesn't act as an insulator, and so does chemically oxidized aluminum, which is 3 to 5 μ thick and can conduct electricity. If the material has conductive requirements, there are to be anti-corrosion, and chemical oxidation can be used.

Methods/steps

Film Printing: in the polymer film printed on a variety of patterns;

Spray primer: many water transfer printing processing materials are coated with a layer of adhesive, if you want to transfer a different pattern, use a different ground color;
The extension of the membrane: so that the membrane is on the water level, and to be flat membrane stretch;
Activation: a special solvent (activator) to transfer the printing film pattern activation into the ink state;
Transfer printing: using water pressure, the pattern after the water transfer printing processing activation is printed on the substrate;
Water washing: will be printed on the remaining impurities of the workpiece washed with water;
Drying: the water transfer printing process is printed on the workpiece drying, temperature from the melting point of the material and the element of the point of view;
Spray Paint: spray transparent protective paint to protect the surface of the printed object;
Drying: to dry the surface of an object which has been sprayed with finish paint.
