The common quality among all metals is the ductility and malleability. This makes these metals very easy to use as wires and sheets. Aluminum is a very useful metal as far as the construction industry in concerned. We shall look at the features of aluminum sheet metal as compared to its contemporaries such as steel.
Utility wise, steel is more in use than aluminum is. However, recent trends have shown that the popularity and usage of aluminum are increasing. It is set to overtake steel in the very near future. This is because of the lightness and corrosion resistant qualities. Secondly, aluminum is abundantly available in the Earth’s crust. The cost of manufacturing aluminum from its bauxite ore is infinitely less than the cost of manufacturing stainless steel.
On the durability front, aluminum and steel have proven the durability in equal measure. Both these metals can withstand extreme climatic changes. Aluminum is more economical and hence is more popular.
You can mold aluminum into any shape and contour. You cannot talk about steel in similar terms. It depends on the nature of the alloy. However, as far as tensile strength is concerned, steel is equal to aluminum.
Fabrication of aluminum is easy. You can subject aluminum sheet metal to various industrial processes such as drawing, pressing, cutting, lasers, machining, and grinding, etc. Welding of aluminum products is also easy. Casting of aluminum is easy in comparison to steel.
Aluminum can withstand all weather. It can withstand extreme heat, cold, and heavy rains without any noticeable change in appearance and behavior. Aluminum has a special quality of forming a protective oxide layer thereby offering protection from rust and corrosion. Stainless steel does not rust but other iron alloys do.
Aluminum is an excellent conductor of electricity. Hence, you find great use of aluminum sheet metal in the manufacturing of aluminum coils for the HVAC industry. Aluminum is a strong metal thereby proving its use in the construction of huge electrical transmission towers, etc.
Aluminum is an environmentally friendly metal. It does not burn very easily. Even at temperatures exceeding 650oC, aluminum alloys do not release harmful gasses into the environment.
We can sum up the qualities of aluminum as follows. The best quality of aluminum sheet metal is its lightness and economic viability. Strength and durability are additional qualities. Environmental friendliness and recyclability make this aluminum sheet metal a favorite of a number of industries.
