Aluminum Alloy and stainless steel are two common materials in life, which are used to make various spare parts products, including stainless steel cabinets, stainless steel tableware, aluminum alloy windows, etc, so what is the difference between aluminum alloy and stainless steel?
Can aluminum alloy and stainless steel be used for doors and windows? Let's get to know.
What is the difference between aluminum alloy and stainless steel?
1. Differences in composition
aluminum Alloy is one of the light metal materials by adding a certain amount of other alloying elements based on aluminum.
The main alloy element in stainless steel is Cr (chromium), and generally the content of Cr (chromium) is at least 10.5%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements.
2. Differences in weight and hardness
the density of aluminum alloy is 2.63~2.85 g/cm, and it has higher strength (& sigma; B is 110 ~ 650MPa), the specific strength is close to that of high alloy steel, and the specific stiffness exceeds that of steel.
3. Differences in corrosion resistance
the reason why aluminum alloy can resist corrosion is that there is oxide film corrosion resistance on the surface, which can prevent further corrosion of internal metals. However, stainless steel mainly contains corrosion-resistant nickel-chromium alloy, so when the application field of the product has the requirement of corrosion resistance, making the shell with stainless steel is the first glare.
Of course, when Zhigao industry produces aluminum alloy shell, it will use baking varnish, electroplating, anodic oxidation and other processes to enhance the corrosion resistance of aluminum alloy shell, the processed aluminum alloy shell can meet the corrosion resistance requirements of most occasions in practical application.
Can aluminum alloy and stainless steel be used for doors and windows?
Aluminum Alloy is one of the popular door and window materials, which can carry out different door opening (window) designs according to customers' requirements, such as push and pull, flat opening, hanging up, etc. It is easy to shape in the manufacturing process and can meet the needs of consumers at different levels. Aluminum alloy doors and windows have the advantages of durability, fire resistance, moisture resistance, rust-resistant, corrosion resistance, good sealing performance, etc. They are generally used in buildings with higher standards. The disadvantage is that the cost is relatively high and the thermal conductivity is relatively high compared with wooden window and copper window. Aluminum alloy doors and windows are one of the most popular doors and windows in the market now.
Stainless steel is one of the materials that many buildings like to use. It has good wear-resistant, corrosion-resistant and oxidation-resistant properties. Its surface is bright and bright, conforms to modern trends, has a sense of fashion, and its own weight is light, it can effectively reduce the load of high-rise buildings.
The above is the difference and use of aluminum alloy and stainless steel introduced to you. Have you understood?
