Alloys are combinations or mixtures of elements.. Metals are alloyed to improve on properties of pure metals such as hardness, strength, corrosion resistance, etc. . Ex.:- Instead of pure aluminum an alloy of aluminum having combination of Al –Zn –Mg – Cu – Mn(A five element alloy ) is used to construct the air craft body.. By.
