The properties of aluminium include: low density and therefore low weight, high strength, superior malleability, easy machining, excellent corrosion resistance and good thermal and electrical conductivity are amongst aluminium’s most important properties.Aluminium is also very easy to recycle.nother of the properties of aluminium is that it is a good reflector of both visible light and radiated heat. Screening EMC. Tight aluminium boxes can effectively exclude or screen off electromagnetic radiation. The better the conductivity of a material, the better the shielding qualities.
