Lowers melting point, saves energy
Cathode (negative electrode)
Anode (positive electrode)
Aluminium is above carbon in reactivity series
They react with oxygen to form CO2CO_2CO2
C+O2ightarrowCO2C + O_2 ightarrow CO_2C+O2ightarrowCO2
Low density (light) and strong when alloyed
Al3++3e−ightarrowAlAl^{3+} + 3e^- ightarrow AlAl3++3e−ightarrowAl
2O2−ightarrowO2+4e−2O^{2-} ightarrow O_2 + 4e^-2O2−ightarrowO2+4e−
