Aluminium prices on Wednesday slipped 20 paise to Rs 237.50 per kilogram in the futures market as participants trimmed their positions on a weak trend in the spot market.

On the Multi Commodity Exchange, aluminium for delivery in December fell 20 paise or 0.08 per cent to Rs 237.50 per kg in 1,605 lots.

Analysts said cutting down of positions by participants on easing demand from consuming industries mainly kept aluminium prices lower.
