what is aluminum strips?
The raw material of aluminum strip is pure aluminum or aluminum alloy cast rolled aluminum coil and hot rolled aluminum coil, rolled into thin aluminum coil of different thickness and width by cold rolling machine, and then cut into aluminum strip of different width.
How is the black aluminum strip made?
Aluminum profiles in the color before, the first oxidation, extrusion good aluminum alloy profile, its surface corrosion resistance is not strong, must be anodized to increase the corrosion resistance of aluminum, wear resistance and appearance of beauty.
The main process is as follows:
(1) Voorbehandeling van het oppervlak: chemical or physical methods are used to clean the surface of the profile, exposing the pure matrix, om een volledige en dichte kunstmatige oxidefilm te verkrijgen. Spiegelend of mat (mat) oppervlakken kunnen ook mechanisch worden verkregen.
(2) Anodische oxidatie: under certain technological conditions, anodic oxidation takes place on the surface of the pretreated profile, and a layer of dense, porous and strong adsorption AL203 film is generated.
(3) afdichting: the pores of the porous oxide film generated after anodic oxidation are closed, zodat de anti-vervuiling, anti-corrosion and wear resistance of the oxide film are enhanced.
De oxidefilm is kleurloos en transparant, using the strong adsorption of the oxide film before sealing, some metal salt is adsorbed and deposited in the film hole, which can make the profile appearance appear natural (zilver wit) outside many colors, zoals: zwart, bronzen, gold and stainless steel color.
The current aluminum alloy profile coloring methods are: anodic oxidation, elektroforese, spraying, and wood grain transfer printing four. Because of its excellent anodic oxidation characteristics, most of the black aluminum strip anodic oxidation process for processing.

Aluminum strip processing technology.
An aluminum strip is a deep - processing product made by cutting aluminum coil. Het is een belangrijke grondstof in de industrie.
According to the different alloying elements contained in the aluminum strip, aluminum strip and aluminum plate are also divided into 8 serie. Echter, de meest gebruikte series zijn 1000,3000,5000 En 8000 serie.
According to the different annealing state of aluminum strip, the aluminum strip can be divided into full soft (O state), half hard (H24) and full hard (H18). The most commonly used should be the full soft series, as the O type is easier to stretch and bend.
The main processing equipment of aluminum strips is the cutting device, which can be divided into the required length and width according to the need.
Around the world, electronic products no longer rely solely on copper tape for raw materials. As the electrical conductivity of aluminum is only lower than that of copper, the substitution of aluminum strip for the copper strip is becoming a worldwide trend.
