Aluminium’s light weight, durability, endless recyclability and high conductivity position it as a true “miracle metal” that can meet the demands of a new world. There can be no better validation of the uniquely sustainable characteristics of aluminium, than the fact that 75% of all aluminium ever produced is still in use today.
