What Are The Main Differences Between Aluminum And Stainless Steel

What Are The Main Differences Between Aluminum And Stainless Steel

It is almost impossible to go throughout your daily life without coming into contact with Aluminum or stainless steel. From your kitchen sink to the car you drive, both of these metals are everywhere. When it comes down to Aluminum and stainless steel, both metals possess a variety of individual applications in sheet metal projects.

Yes, these two metals are similar in appearance. However, as similar as these two metals appear, they both distinct qualities that make them unique to one another.

The Differences Between Aluminum and Stainless Steel    

Although Aluminum and stainless steel appear similar, these two metals are quite different. Here are a few of those differences to keep in mind for the next sheet metal project.

Strength to Weight Ratio

  • Aluminum is one third the weight of stainless steel
  • Aircrafts are made from Aluminum due to it being lightweight yet durable
  • Aluminum is not as strong as stainless steel

Cost of Metals

  • Aluminum is cheaper than stainless steel
  • Aluminum sheet metal takes less time and effort to refine
  • The steel industry has $900 billion turnover

Electrical Conductivity

  • Aluminum is an excellent conductor of electricity
  • High voltage power lines are made from Aluminum due to its high conductance, lightweight, and resistance to corrosion
  • Stainless steel is a poor conductor of electricity


  • Aluminum is cheaper to cut and form
  • Stainless steel’s high resistance to abrasion makes it challenging to work with

Thermal Properties

  • Aluminum becomes soft at 400 degrees
  • Stainless steel can be utilized at higher temperatures

Welding Capabilities

  • Stainless steel is quite easy to weld
  • Aluminum is quite difficult to weld

Corrosion Resistance

  • Aluminum has oxidation and corrosion resistance due to the passivation layer
  • Aluminum turns white and pits when oxidized
  • Stainless steel is made up of nickel, copper, chromium, and manganese. Chromium is an added agent that provides corrosion resistance
  • Stainless steel is non-porous making its resistance to corrosion much higher
