A unique combination of properties puts aluminium and its alloys among the most versatile of engineering and construction materials. All alloys are light in weight, yet some have strengths that are greater than structural steel. Most alloys can be easily worked into a variety of forms and can accept a wide range of surface finishes. The majority of alloys are highly durable under most service conditions. Aluminium and most of its alloys also have the benefit of good electrical and thermal conductivities and high reflectivity to both heat and light.
A key benefit of aluminium is only a small fraction of energy is required to recycle into new material, a major advantage in the present economic climate.
