What is the color of black coated aluminium sheet?
The black color coated aluminum sheet is not a black aluminum sheet, but is treated by a special process. Birinchidan, the aluminum sheet is placed in the corresponding electrolyte (sulfat kislota kabi, xrom kislotasi, oksalat kislotasi, va boshqalar.) as an anode. Alumina plate formed by electrolysis. The second is to coat the anodized aluminum plate to cover it with a black oxide layer to obtain a black anodized aluminum plate.

10 features of black color coated aluminum sheet
1. Aluminum metal has low density and light weight: ning zichligi 1 series aluminum plate is close to 2700kg/m³, qaysi haqida 35% of the density of iron.
2. The hardness of aluminum metal can be strengthened: 1000 series pure aluminum plate can be more than doubled in strength by cold working. By adding metal elements such as Mg, Cu, Mn, va boshqalar., the strength of the metal can be further enhanced.
3. Aluminum has good plasticity and easy processing: aluminum has good metal properties and good plasticity and can be rolled into sheets and foils; drawn into pipes and filaments. Can be applied to most factory manufacturing.
4. Corrosion resistance and oxidation resistance of metal aluminum: the aluminum plate is easy to reacts with oxygen in the air, and a dense three-Al₂O₃ protective film is formed on the surface of the metal, and it is not easy to be damaged. Resistant to most acids and organics.
5. Aluminum metal has no low-temperature brittleness: at low temperature, the strength and plasticity of aluminum plate will not decrease as the temperature decreases, and no deformation will occur.
6. The aluminum plate has good electrical and thermal conductivity: the electrical and thermal conductivity of aluminum is inferior to that of silver, mis, va oltin.
7. The surface of the aluminum plate is highly reflective: the polished surface of the aluminum has a reflectivity of more than 80% for white light and has good reflection properties for infrared, ultrabinafsha, electromagnetic waves, and thermal radiation.
8. No magnetism, no sparks when impacted.
9. Good sound insulation: sound absorption.
10. The surface of the aluminum plate is beautiful: the bright metal color has a great ornamental value.
