Isint there delivery type contracts for alumini and related commodities. Or is it compulsory cash settlement only?
what if i want to take original delivey, doesn’t the need for demat account arise ??

No, it might come to ur office by courier.

Compulsory delivery contracts has actual physical delivery, you can’t take it into your demat account. For example, if you want to give/take Gold, it happens in exchange designated warehouse in the various cities in India. They don’t send it to you, you will have to go to a warehouse and either deliver or take delivery.
