Anodizing
an electrolytic oxidation process that thickens the protective surface oxide film to improve the corrosion and wear resistance
Cladding
gives the corrosion resistance of pure aluminium with the strength of strong alloy, done by placing a pure aluminium plate onto an alloy and then hot rolling.
Aluminium/Lithium alloys
have good fatigue crack propagation resistance and are useful in aerospace applications
