Besides, a weak trend overseas weighed on prices.
At the Multi Commodity Exchange, aluminium for delivery in January edged down by 75 paise, or 0.53 per cent, to Rs 140.80 per kg in a business turnover of 3,510 lots.
Likewise, the metal for delivery in February was trading lower by a similar margin to Rs 140.85 per kg in 1,877 lots.
Analysts said offloading of positions by participants due to slackened demand from consuming industries in the physical market and weak trend overseas, led to a decline in aluminium prices at the futures trade.
