When a more reactive element displaces less reactive element from it's compound. Such type of reaction is known as Displacement Reaction.
i.e.
AB + C -----› AC + B
2Al (s) + 3CuCl2 (aq) ----› 2AlCl3 (aq) + 3Cu (s)
When Aluminium (Al) react with Copper Chloride (CuCl2) then Aluminum Chloride (AlCl3) and Copper (Cu) is produced.

Potassium = K [High Reactivity Series]
Sodium = Na
Calcium = Ca
Magnesium = Mg
Aluminum = Al
Zinc = Zn
Iron = Fe
Lead = Pb
Hydrogen = H
Copper = Cu
Silver = Ag
Gold = Au [Low Reactivity Series]
From the above reactivity series Aluminum (Al) is more reactive than Copper (Cu). That's why it displaces Copper Chloride (CuCl2) from it's compound and form new compound.
