Aluminium has a density approximately one third of steel or cooper. Its light weight and high strength makes it easy to transport and a better option than some commercial metals.
A thin layer of aluminium oxide forms on the surface of aluminium when it is exposed to air, this gives it great resistance to corrosion.
Strength in varied conditions
Normally aluminium is soft and ductile. Many commercial users require more strength than aluminium affords, however mechanical properties can be increased by adding alloying elements, and tempering to give a higher tensile strength.
Aluminium is a great heat conductor; it is about three times as thermally conductive as steel.
Each steel grade has a number of explicit attributes associated with the particular standard that it complies with, whereas a general term can cover more than one grade or standard. When steel is purchased to meet a particular standard, the purchaser is assured that it will meet certain chemistry and/or mechanical property requirements.
However, other attributes are less obvious, but can have a significant effect on the performance of the steel. Many of these attributes are learned through experience. When users do not have the experience or background in using particular steel grades, they may not be aware of precisely which grade offers the most suitable attributes for their purpose.
