What's the difference between stainless steel plate and alloy aluminum plate?

Stainless steel plate has smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acid, alkaline gas, solution and other media. It is an alloy steel that is not easy to rust, but it is not absolutely rust-free. Stainless steel plate refers to the steel plate that can resist the corrosion of weak media such as atmosphere, steam and water, and acid-resistant steel plate refers to the steel plate that can resist the corrosion of chemical corrosive media such as acid, alkali and salt. Stainless steel plate came out in the early 20th century, and it has a history of 1 century.

Alloy aluminum plate is made by adding various alloying elements (the main alloying elements are copper, silicon, magnesium, zinc and manganese, and the secondary alloying elements are nickel, iron, titanium, chromium and lithium, etc.). ) in the process of aluminum plate processing, so as to improve the mechanical properties and chemical indexes of aluminum plate. Alloy aluminum plate has some special properties that pure aluminum plate does not have, and is widely used in special environments, such as ships, refrigerators, molds, aerospace equipment and so on.

Alloy aluminum plate-1. Classification of alloy aluminum plates 1. Aluminum alloy plates can be divided into 2×××× aluminum alloy plates (Al-Cu), 3×××× aluminum alloy plates (Al-Mn), 4××××× aluminum alloy plates (Al-Si) and 5××××× aluminum alloy plates (Al-Si).
