Traders said besides subdued demand from consuming industries, a weak trend overseas mainly led to the decline in copper and nickel prices.
Meanwhile, copper for delivery in three months lost 0.7 per cent on the London Metal Exchange.
In the national capital, copper mixed scrap and nickel plate (4x4) slipped by Rs 2 each to Rs 378 and Rs 855-860 per kg, respectively.
Following are today's metal rates (in Rs per kg):
Lead ingot Rs 80, lead imported Rs 86, aluminium ingots Rs 155, aluminium sheet cutting Rs 151, aluminium wire scrap Rs 151 and aluminium utensils scrap Rs 149.
