Nickel Wire 0.025-mm Diameter 99.9% Pure

Obviously you need to analyze the market to determine all potential users and where they are and what they now buy.

I also want to know who has the potential to buy a million meters of this fine nickel wire?

Start by talking to existing customers. Ideas will come from there. Remember that every complaint is doing the business a favo(u)r.

Buy it yourself and sell in smaller quantities....

Try researching online what markets and types of customers actually use this wire and what for. This should give you a better idea of who the big end customers are, then you can target them directly.

Try heating element and vacuum tube manufacturers too.

Large companies that stock and sell copper winding wire or specialty wire may also be potential customers. A million meters is still only about 4.4kg, and 1kg bobbins seem to be common, so they may be interested in stocking it.
