In futures trading at the Multi Commodity Exchange, copper for delivery in June fell Rs 1.85, or 0.59 per cent, at Rs 309.45 per kg, in a business turnover of 2,400 lots.
The metal for delivery in far-month August fell by a similar margin to trade at Rs 314 per kg in 21 lots.
Analysts attributed the fall in copper futures to profit-booking by speculators who trimmed their positions at existing levels but metal's strength at the London Metal Exchange (LME), capped the losses.
