Tracking a weakening global trend, copper prices fell by Rs 6.40 to Rs 409.50 per kg in futures trade today.
Trading sentiment turned bearish after copper fell to a seven-week low in New York on concerns that growth in China, the world's biggest metals user, may moderate as indicated by a decline in manufacturing index in April.
At the Multi Commodity Exchange, copper for delivery in June fell by Rs 6.40, or 1.54% to Rs 409.50 per kg, with a business turnover of 10 lots.
Similarly, the metal for delivery in August declined by Rs 6.30, or 1.50% to Rs 414.85 per kg, with an open interest of two lots.
Market analysts said besides a weakening global trend, fall in spot market demand pulled down copper futures prices.
Meanwhile, copper futures for July delivery fell by 1.4% to $4.12 a pound on the Comex in New York, the lowest level since March 15.
