Aluminium fell 0.6 per cent to $US1,922 per ton, while nickel prices fell the most, giving up 2.4 per cent to trade at $US19,395 per ton.
Despite Friday's downward correction, industrial metal prices have been well supported in recent weeks by data showing improvement in the China's manufacturing sector and hopes the Chinese government will continue to take steps to support the country's economy.
Nickel prices have risen as a ban on ore exports from top producer Indonesia has limited supply of the metal to consumers, such as Chinese nickel pig-iron producers.
