What are the properties aluminum sheet covered?
5, ecological characteristics: chemical passivation of aluminum plate is not no effect on health, which can be used in food processing. Many professional organizations test report confirmed that the product is environmentally harmless. Aluminum plate can be recycled.
Aluminum and stainless steel plate may be comparable, but the price is only about one-third of the stainless steel is widely used in: 1, car, motorcycle muffler, exhaust pipe, fuel tank. 2, furnaces, heat exchangers, dryers, air conditioning. 3, household water heater, gas stove, bread box, chimney, microwave, food processing machinery, electric oven, cooking utensils. It can also be used to cover walls, ceilings, and other structures of the insulating member and the like.
4, corrosion resistance: In the hot-dip coating process, the molten aluminum Al2O3 protective layer is a layer formed immediately react with the oxygen in the air, the surface of the steel sheet immediately passivated. The protective layer is very stable and does not dissolve in water, even though the steel surface is scratched, the protective layer also has a self-healing capabilities. Thus, aluminum plate to have a strong chemical corrosion corrosion resistance.
3, the mechanical strength: at room temperature, consistent with the mechanical strength of the aluminum plate and its substrate. At the same temperature 480 ℃, the strength of aluminum plate is 10 times the strength of aluminum sheet thickness can be reduced and therefore at least 30%.
2, heat reflective: at 480 degrees Celsius temperature, aluminum plate can reflect 80% of the heat into the shot. Thus aluminum plate can be made efficient thermal insulation barrier or reflector in high temperature applications through efficient heat reflection in the furnace temperature rises rapidly.
Characteristics of aluminum plate
1, high temperature: Due to the particular combination of substrate and coating microstructure of the steel sheet to form an iron alloy, making aluminum plate has excellent temperature resistance. At 450 ℃, it can ensure high reflectivity. At above 480 ℃, the appearance of gray coating. At up to 650 ℃, the protective layer to prevent oxidation of the steel sheet remains intact, no any loss.
