Modulus of elasticity of steel and aluminum
Modulus of elasticity, or Young's modulus, is the magnitude of a material that expresses the ratio of strain to stress; in other words, it indicates the propensity to deform under the action of a loading force. Aluminum has a coefficient of elasticity that is about one-third that of steel, so it will tend to deform much more easily when subjected to a force. This makes aluminum very ductile and workable, but at the same time less strong. In contrast, steel is a material that can bear the load of very heavy weights over large areas without deforming.
To summarize, aluminum is more durable, lighter, and more malleable, while steel is stronger, stiffer, and for obvious reasons a cheaper material than aluminum. Both are viable alternatives, however, the choice must be made on the basis of the 'end use of the metal profiles.
