A metal often used for its great qualities – it’s lightweight, corrosion-resistant and a good electric conductor. Depending on the specific class, aluminium can be extremely well malleable and provide great strength.
Considering what it brings to the table, it is not expensive. When comparing it to carbon steels though, it is noticeably pricier. Aluminium uses include food processing equipment (corrosion resistance), aircraft and automotive structures (lightweight), heat exchangers and cooking utensils (heat conductor), marine applications (corrosion resistance and strength), etc.
