alloy

It has the benefit over steel in that its’ tensile strength increases with decreasing temperature whilst retaining its toughness. Pure aluminum metal is usually regarded non-toxic to humans, but aluminum compounds, and specifically aluminum ions, can lead to side effects like memory loss and nervous program harm when present in very higher levels in the human body. Recycling aluminium only demands about five per cent of the energy utilized to produce a new product from virgin components. Following the discovery of the Hall–Héroult method, aluminium prices dropped, and the alloys started being applied to make many everyday household things —...
