Aluminium is very useful metal and used as a lightweight construction material eg greenhouse frames. Aluminium can be made more resistant to corrosion by a process called anodising. Aluminium is a reactive metal but it is resistant to corrosion. This is because aluminium reacts in air to form a layer of aluminium oxide which then protects the ...
