DIFFERENCES BETWEEN ALUMINIUM AND STAINLESS STEEL

Aluminium and stainless steel might look similar, but they are actually quite different. The metals look similar but they different in that one is an alloy while the other is not. They also different in terms of composition, density, strength etc. 

Aluminium is typically not as strong as steel, but it is also almost one third of the weight. This is the main reason why aircraft are made form aluminium. Aluminium is an element. It not a combination two element like in the case of stainless steel. Stainless steel does not rush or corrode easily like other metals. Aluminium has a high oxidation and corrosion resistance mainly due to its passivization layer. The amount of chromium used varies from 10 to 30 percent. Chromium is used so as to make the metal anti - corrosive and rust resistant. Chromium reacts with air to form an oxide film which protects the steel. Stainless steel has a variety of applications including those found in home and restaurant kitchens for making appliances such as rice cookers and utensils.

 Aluminium is a bit weaker as compared to stainless steel. Aluminium is fairly soft and easier to cut and form. Due to it resistance to wear and abrasion, Stainless can be difficult to work with. Stainless steel is very strong and heavy.

Aluminium is available cheaply and it does not require much processing. It's also good conductor or electricity, hence it is used in making power cable. Aluminium has a much better thermal conductivity (conductor of heat) that stainless steel. One of the main reasons it is used for car radiators and air conditioning units. Aluminium does not rust due to the formation of an oxide coating on it surface. Aluminium preferred in making boilers and other heating vessels since it does not react with the contents, and conducts heat effectively. Stainless steel is a really poor conductor compared to most metals. Aluminium is a very good conductor of electricity. Due to it high conductance, light weight, and corrosion resistance, high - voltage overhead power lines are generally made of aluminium.

Stainless steel, on the other hand, is expensive due to the lengthy refining process and alloying. In most cost conscious projects such as construction, aluminium is used instead of stainless steel. Aluminium is typically cheaper that stainless steel.

Stainless can be used at much higher temperatures that Aluminium which can become very soft above about 400 degrees.
