Why are all steels Alloys Steel is a combination of Iron and Carbon
Give 3 properties that make aluminium a useful metal Low Density --- Resistant to Corrosion --- Malleable ---
3 Reasons why titanium is expensive Electrolysis is needed as high in reactivity series --- Titanium reacts with carbon making it brittle --- several stages are needed to extract from ore ---
3 reasons why we should recycle aluminium and titanium To prevent Environmental damage --- To make earth supply last longer --- It is more Sustainable and CHEAPER
