I'd rather been wondering that myself during this thread. The name "scrap dealer" ought to serve as some sort of notice that they're there to deal in scrap metal..
Sure, in times when business has been slow some of them may have been happy to keep and sell on unscrapped stuff, but that isn't the case now. And surely if you don't want something to be scrapped then selling it to a //scrap dealer// isn't the smartest move..
