Aluminium prices on Monday fell by Rs 1.15 to Rs 181.10 per kg in the futures market as participants trimmed their positions amid a weak trend in the spot market. On the Multi Commodity Exchange, aluminium for delivery in April declined by Rs 1.15, or 0.63 per cent, to Rs 181.10 per kg in 1,772 lots.

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