10 Differences Between Aluminum and Stainless Steel

What is the difference between Aluminium and stainless steel? IBC Group Manufacturer & Supply this product for decade years. We have rich experience to provide you with high quality products. We have other steel coils and sheet. Thought, aluminum and Stainless Steel might look similar. But they are actually quite different. Keep these 10 differences in mind when deciding which type of metal to use in your next project.

1. Strength to weight ratio.

 Aluminum is typically not as strong as steel, but it is also almost one third of the weight. This is the main reason why we use alumium to make aircraft.

2. Corrosion Difference Between Aluminium and Stainless Steel.

Stainless steel is made up of iron, chromium, nickel, manganese and copper.  The chromium adds as an agent to provide corrosion resistance.  Also, because it is non-porous the resistance to corrosion is increased. Aluminum has a high oxidation and corrosion resistance mainly due to its passivation layer.  When aluminum is oxidized, its surface will turn white and will sometimes pit. In some extreme acidic or base environments, Aluminum may corrode rapidly with catastrophic results.

3. Thermal Conductivity.

 Aluminum has a much better thermal conductivity (conductor of heat) than stainless steel. One of the main reasons it is used for car radiators and air conditioning units.

4. Cost Difference Between Aluminium and Stainless Steel.

Aluminum is typically cheaper than stainless steel.

5. Workability.

Aluminum is fairly soft and easier to cut and form. Due to its resistance to wear and abrasion, Stainless can be difficult to work with. Stainless steels are harder and are especially harder to form than aluminum.

6. Welding.

Stainless is relatively easy to weld, while Aluminum can be difficult.

7. Thermal properties.

If temperature higher above 400 degrees, Aluminum is much better than Stainless. Because Stainless will become very soft above about 400 degrees.

8. Electrical Conductivity.

Compare to most metals, Stainless steel is a really poor conductor. Aluminum is a very good conductor of electricity. Due to its high conductance, light weight, and corrosion resistance, high-voltage overhead power lines are generally made of aluminum.

9. StrengthDifference Between Aluminium and Stainless Steel.

Stainless steel is stronger than Aluminum (provided weight is not a consideration).

10. Effect on Foods.

Come to the end, stainless steel is less reactive with foods. Aluminum can react to foods which may affect color and flavor.
