What makes aluminum alloys a cornerstone of modern engineering? This article dives into the diverse chemical compositions that give aluminum alloys their unique properties, from high strength to excellent corrosion resistance. You’ll discover how specific elements transform aluminum into a material crucial for aerospace, automotive, and construction industries. Read on to understand the intricate balance of elements that make aluminum alloys indispensable.
Aluminum-based alloys, supplemented with a certain amount of other alloying elements, are one of the light metal materials.
In addition to the general characteristics of aluminum, these alloys have specific properties due to the type and amount of alloying elements added. The density of the aluminum alloy is 2.63~2.85g/cm3, and it has a high strength (σb is 110~650MPa), almost equal to that of high-alloy steel.
Its rigidity surpasses steel, and it has excellent casting and plastic processing performance, good electrical and thermal conductivity, corrosion resistance, and weldability.
It can be used as a structural material and is widely used in aerospace, aviation, transportation, construction, mechanical and electrical engineering, lightweighting, and daily necessities.
