Spark plug which one has the highest conductivity?

I have heard that copper has higher conductivity then platinum or iridium spark plugs ,,is this true?

It probably does but that doesn't make it better than the platinum/iridium tipped plugs. Those metals are much harder than copper so you can manufacturer the plugs with a smaller surface area and thus concentrate the spark better and thus making it stronger.

I am wrong here?

So copper will perform better but will have to be gapped over time..
Cheaper plug and better performance?

copper plugs only last a year, so if you are willing to replace them often, then they are cheaper and better performing than platinum plugs

very interesting info...I dont mind replacing them once a year to gain a hp or two. Plus gas mileage might get better too right?
