Since stainless steel and aluminum look so similar, many people believe they are the same type of metal. But this, of course, is not true. Although stainless steel and aluminum are used in similar industries, their qualities are different in many ways. Continue reading to learn some fun facts about both these metals, and the primary difference between them.

Stainless Steel

Stainless steel is a steel alloy used for several reasons, and in several industries. It is highly resistant to corrosion, tarnishing, and rust. The most common uses for stainless steel include food handling and processing, surgical instruments, medical devices, air crafts, appliances, hardware, and more. The common alloying ingredient in stainless steel is chromium, but nickel, copper, manganese, iron and molybdenum are also used. Stainless steel usually contains anywhere from 15% to 30% alloy content.

Aluminum

Aluminum is a silvery-gray, light-weight, non-magnetic metal used in countless industries and for several purposes. The most well-known use for aluminum is food and soda cans. But aside from canned goods, aluminum is also widely used in the automaker and aerospace industry for its ductile, corrosion-resistant qualities and more.

Comparisons

As for strength and weight, steel is stronger and weighs more. Aluminum is only one-third the weight of stainless steel, but this is why it is top-choice for automotive and aerospace manufacturing.

Both metals are highly-resistant to corrosion, but since stainless steel is non-porous, it is more resistant than aluminum.

Both metals are also good thermal and electrical conductors, but aluminum retains higher thermal conductivity. This is why it is used to manufacture things like car radiators and air conditioner units.

In terms of malleability, aluminum takes the cake. It is much softer and easier to work with compared to stainless steel. On the other hand, stainless steel is much easier to weld than aluminum.

As for price, aluminum is much cheaper.
