The use effect of aluminum impeller and steel impeller is the same, and it generally depends on the occasion of use to decide which impeller to use.
1. The specific gravity of steel is 7.85, while the specific gravity of aluminum is about 2.7 (usually aluminum alloy is used,pure aluminum is used for low strength and cannot be used), with a weight difference of nearly three times.
Due to its lightweight, aluminum can correspondingly reduce power consumption and achieve energy-saving effects.

2.The melting point of steel is about 1500 degrees, and that of aluminum is 660 degrees. Aluminum impellers must not be used at high temperatures.

3. Steel is prone to oxidation in the air (such as galvanizing before anti-corrosion treatment), while aluminum can form a dense oxide film on the surface after oxidation,
making it impossible to continue oxidation. Aluminum impellers are superior to steel impellers in slightly corrosive atmospheres.

4. The strength of steel is greater than that of aluminum. Due to strength limitations, the impellers of large fans are generally made of steel.
