Advantages of aluminum zinc plate
发布时间:2021-04-06 06:18:23浏览次数:356
Since the advent of aluminum zinc plate has been widely used in construction, home appliances and other major industries. Due to the continuous expansion of the scope of application, the formability and various properties of the products for the steel plate are continuously improved, resulting in the aluminum zinc plating steel plate which is superior to the hot-dip galvanized steel plate in some properties. Al Zn coated steel sheet is a kind of Al Zn alloy coated steel sheet, which is made of cold rolled and hard rolled steel sheet with various strength and thickness by hot dip. The coating consists of 55% Al, 43.5% Zn, 1.5% Si and appropriate trace elements.
In the process of production and processing, the performance of aluminum zinc plating is better than that of hot dip galvanizing
What are the advantages of aluminum zinc plate?
1. Processability
The processing performance of Al Zn coated steel sheet is similar to that of hot dip galvanizing, which can fully meet the processing requirements of rolling, stamping, bending and other forms.
2. Corrosion resistance
The test is carried out on the same thickness, coating and surface treatment of hot-dip galvanized steel sheet and aluminized galvanized steel sheet. Aluminum zinc plating has better corrosion resistance than hot dip galvanizing, and its service life is 2-6 times of that of ordinary galvanized steel sheet.
3. Light reflection performance
The ability of aluminum and zinc to reflect heat and light is twice that of galvanized steel sheet, and the reflectivity is greater than 0.70, which is better than 0.65 specified by EPA energy star.
4. Heat resistance
Ordinary hot-dip galvanized products are usually used at a temperature of not more than 230 degrees, which will change color at 250 degrees, while aluminized zinc sheet can be used at 315 degrees for a long time without changing color. At 300 ℃ for 120 hours, the color change of heat-resistant passivated aluminum zinc plate is much lower than that of aluminum plate and aluminum plate.
