We can meet a lot of aluminum alloy and stainless steel items in our life. There are many differences between them. Let's see which one is better today?

1. Different high temperature resistance
stainless steel can resist high temperature, with melting point of 1200-1500 degrees Celsius; Aluminum alloy cannot withstand too high temperature, with melting point of 500-800 degrees Celsius.

2. Different hardness
aluminum Alloy has low density, but high strength, close to steel and good plasticity; Stainless steel is nickel-chromium alloy, and its hardness is higher than that of aluminum alloy.

3. Different prices
stainless steel is expensive and aluminum alloy is cheap.
4. Different industrial applications
stainless steel has heat resistance, oxidation resistance, good formability and good weldability, and can be used as ultra-high strength materials in nuclear industry, aviation and aerospace industry; aluminum Alloy for processing requires good formability but does not require high-strength parts, such as chemical products, food industry devices and storage containers, printing plates, nameplates, reflective appliance, etc.

5. Different surface treatments
stainless steel surface treatment includes surface bright treatment, surface whitening treatment and surface coloring treatment; Aluminum alloy treatment includes electroplating, spraying, anodic oxidation, etc.

they have their own characteristics and advantages, so their functions are different in different places. They cannot absolutely say which one is good, as long as it is suitable, it is the best! Only in this way can the value of goods be maximized.
