First, the difference in appearance
Aluminum alloy looks brighter, higher gloss; and stainless steel appearance is relatively low-key, showing a more calm temperament.
Second, material difference
Aluminum alloy is a kind of aluminum as the main alloying element of metal materials, lightweight, high strength, good conductivity, easy to process and so on; and stainless steel is a kind of high strength, corrosion resistance, not easy to deformation of steel, the main alloying element is chromium, nickel and so on.
Third, the performance difference
1. Density: aluminum alloy density is small, about 1/3 of stainless steel.
2. Mechanical properties: aluminum alloy is relatively light, more flexible than stainless steel is easy to bend; stainless steel is much stronger, less susceptible to external forces.
3. Corrosion resistance: stainless steel has good corrosion resistance, can maintain excellent performance in harsh environments; aluminum alloy requires specific surface treatment to enhance its corrosion resistance.
Fourth, the applicable scene
Aluminum alloy is often used in the manufacture of aircraft, automobiles, ships, etc. because of its light weight, good rigidity, corrosion resistance, etc.; and stainless steel is often used in the production of chemical industry equipment, construction and decoration materials, etc. because of its high strength, good abrasion resistance, good corrosion resistance.
Five, how to distinguish
1. magnetic difference: stainless steel has a certain degree of magnetism, while the aluminum alloy does not have magnetic.
2. weight difference: aluminum alloy is lighter than stainless steel. 3. corrosion difference: aluminum alloy is more stable than stainless steel.
3. Corrosion difference: aluminum alloy is easy to oxidize and change color in the environment, while stainless steel can keep bright for a long time.
In summary, although aluminum alloy and stainless steel in terms of appearance, material and performance, there are certain differences in actual use, we need to choose the most suitable material according to the specific application scenarios, in order to achieve the best results.
