An aluminium alloy specifically designed to rust.(Metals and alloys)

A novel aluminium alloy that rusts when buried in soil has been developed by a group at Tokai University.

Although rusty aluminium sounds like an oxymoron, the university team has managed to create a highly corrosive aluminium alloy for the specific purpose of facilitating recycling and reducing the environmental burden when the material gets buried as waste.

The new alloy is made by melting aluminium together with magnesium and lithium, a metal that readily reacts with air and water. This type of alloy is normally difficult to make, but the researchers solve
