1. Material
Aluminum alloy pipes are mainly composed of aluminum, magnesium, silicon, zinc and other metal elements, while stainless steel pipes are mainly composed of iron, chromium, nickel and other metal elements.
2. Weight
Aluminum alloy pipes are lighter than stainless steel pipes. The specific gravity of aluminum alloy is about 2.7g/cm³, while the specific gravity of stainless steel is about 7.93g/cm³, so aluminum alloy tubes are more suitable for scenarios that need to be lightweight.
3. Strength
Aluminum alloy pipes have comparatively higher strength, but stainless steel pipes have higher strength.
4. Electrical conductivity
Due to the good electrical conductivity of aluminum, aluminum alloy tubes are widely used in electronics, electrical and other industries.
5. Color
The common colors of aluminum alloy pipes are silver, black, gold, gray, etc., while stainless steel pipes are usually silver or gray.
6. Processing method
Aluminum alloy pipes are suitable for cold or hot working and can be processed by deep drawing, drawing, welding, etc., while stainless steel pipes are usually cold worked, such as cold drawing, cold rolling, welding, etc.
