At the Multi Commodity Exchange, nickel for delivery in September declined by Rs 15.50, or 2.24 per cent to Rs 676.80 per kg in business turnover of 2,341 lots.
Likewise, the metal for delivery in far-month October contracts traded lower by Rs 15.20, or 2.18 per cent to Rs 682.60 per kg in 154 lots.
Analysts said apart from a weak trend overseas, sluggish demand from alloy makers in the domestic spot market, mainly weighed on nickel futures.
