Where to find the futures of pewter metal?

Question

a company or futures relates with pewter metal

Answer 1

If you literally mean futures as in commodity futures, pewter is an alloy of tin, lead and other metals and commodities deal entirely with pure metals like gold, copper, steel, etc.
If you are stumbling over wanting a company that has a future in the metal or information on its future, you will find that there is very little. It has been almost entirely replaced with Britannia Metal because food holding containers with lead in them are frowned upon and plated metals are cheaper than they were in the past.
