At the Multi Commodity Exchange, nickel for delivery in October month declined by 10 paise, or 0.01 per cent to Rs 668.20 per kg in business turnover of 148 lots.
However, the metal for delivery in September contracts held steady at Rs 662.50 per kg in 2255 lots.
Analysts said apart from a weak trend overseas, easing demand from alloy makers in the domestic spot market, mainly weighed on nickel futures.
