The performance of aluminum coil is not small
Aluminum coils can be widely used in architectural decoration, machine housing, lamps and lanterns, consumer electronics, handicrafts, household appliances, etc. Aluminum coil, its standard thickness oxide film (3μm), does not change color, corrosion, oxidation, and rust in indoor use for a long time. Aluminum coils with thick oxide film (10μm) can be used outdoors, and can be exposed to sunlight for a long time without changing color.
There are also aluminum coils that have undergone anodization, which improves their hardness and wear resistance, up to 250-500 kg/mm2, good heat resistance, hard anodized film melting point as high as 2320K, excellent insulation, The breakdown voltage is as high as 2000V, and the corrosion resistance is enhanced. It will not corrode in ω=0.03NaCl salt spray for thousands of hours. If there are a large number of micropores in the thin oxide film, it can absorb various lubricants. In this way, it is also suitable for manufacturing engine cylinders or other wear-resistant parts.
