The full name of aluminum plated steel plate is "hot-dip aluminum plated steel plate", which is similar to hot-dip galvanized steel plate in terms of manufacturing process. But its heat resistance is better than galvanized steel plate.
At present, steel mills in China, South Korea, and Japan in Asia are able to produce this product.
According to different usage purposes, in order to further enhance the corrosion resistance of materials, there are also special specification products that undergo surface post-treatment (chromate treatment, no (hexavalent) chroming treatment).

1. High temperature resistance: Due to the specific combination of steel plate substrate and coating structure, an iron aluminum alloy is formed, which gives the plated aluminum plate excellent high temperature resistance. At 450 ℃, it can ensure extremely high reflectivity. At temperatures above 480 ℃, the appearance of the coating turns gray. At temperatures up to 650 ℃, the protective layer that prevents oxidation of the steel plate remains intact without any detachment.

2. Heat reflectivity: At a high temperature of 480 degrees Celsius, aluminum plated plates can reflect 80% of the incoming heat. Therefore, aluminum plating can be used to create efficient insulation barriers or heat reflectors in high-temperature applications, which can rapidly increase the temperature inside the furnace through effective heat reflection.

3. Mechanical strength: At room temperature, the mechanical strength of aluminum plated plates is consistent with that of their substrates. At the same high temperature of 480 ℃, the strength of aluminum plated steel plate is 10 times that of aluminum plate, so the thickness of the steel plate can be reduced by at least 30%.

4. Corrosion resistance: During the hot-dip coating process, molten aluminum immediately reacts with oxygen in the air to form a protective layer of Al2O3, which immediately passivates the surface of the steel plate. This protective layer is very stable and insoluble in water, and even if the surface of the steel plate is scratched later, this protective layer has self-healing function. Therefore, aluminum plated plates have extremely strong corrosion resistance to chemical corrosion.

5. Ecological characteristics: Aluminum plated plates without chemical passivation have no impact on health and can therefore be used for food processing. Many professional organizations' testing reports have confirmed that it is an environmentally friendly product that is harmless to the human body. Aluminum plated plates can be completely recycled. Aluminum plated plates can be comparable to stainless steel, but their price is only about one-third of stainless steel.

They are widely used in:

1. car and motorcycle mufflers, exhaust pipes, and fuel tanks.

2. Combustion furnace, heat exchanger, dryer, air conditioner, etc.

3. Household water heaters, gas stoves, bread boxes, chimneys, microwave ovens, food processing machinery, electric ovens, and cooking utensils. It can also be used for building covers, walls, ceilings, and other insulation components.

6. Other: Standard MAG and TIG welding can be used for processing. It can perform forming processes such as stretching, stamping, and tube drawing. The coating has long-lasting luster, superior corrosion resistance, and weathering resistance.
