ABC of aluminium alloy profile

Aluminium and aluminium alloy introduce:

Aluminium: It is metal of a kind of silvery white, in the lithosphere content is next to oxygen and silicon platoon to be in the 3rd. Aluminous density wants 2.7 × only 103 ㎏ / M3, for the 1/3 of rolled steel. Aluminium is very soft, strength is not great, plasticity is first-rate having extend a gender crackajackly, can pull filament and make friends to become foil piece, have crackajack machine processability. See more have aluminum foil, aluminous lead

Aluminium alloy data: Aluminium passes additive for instance magnesian (Mg) , manganese (Mn) , copper (Cu) , silicon (Si) with other a few elements can change aluminous function inside very big range, make the aluminium alloy material with a variety of superior functions. See more have a plane, car hub, build aluminium board to wait.
Special specification was not done to be in in later development, indicate aluminous material all is aluminium alloy profile.

Aluminous profile appearance handles the introduction:

The effect of outside processing:
Ascensive appearance is anti-corrosive function, hold to outside burnish not easy cut.
Make profile appearance is had fight efflorescent function stably, those who hold to profile appearance is beautiful.
Satisfaction builds the request of artistic facial expression, make build the outward appearance that has charm for a long time.
The method of outside processing

Positive pole oxidizes:
In be solution of zincous park electrolyte with aluminium or aluminium alloy finished product, use electroanalysis the effect, make its appearance makes the progress of alumina film, call aluminium and processing of oxidation of aluminium alloy positive pole. Commonly used method is dc law of vitriolic and zincous oxidation.

Technical progress: Outside pretreatment -- zincous oxidation -- boiling water sealing of hole

Electroanalysis chromatically:
Electroanalysis the metallic ion ooze in solution recovers from an illness to pile up and make to bottom of velar small opening the method of velar layer chromatically, call electroanalysis chromatically law, also weigh electrolysis 2 times.
Technical progress: Outside pretreatment, dc is vitriolic and zincous oxidation, electroanalysis chromatically, boiling water sealing of hole or electrophoresis besmear dip.

Electrophoresis lacquer:
Oxidize with positive pole (chromatically) the finished product after serves as positive pole, aluminium or stainless steel are cathode, in solution of colophony of park hot solidify acrylic brightly lit, below the effect of outer electric field, the coating particle that takes negative electric charge moves to finished product, make a paint film that contains gooey sex in its appearance next.
