Hello all - Rookie scrapper here. I scrapped an all-in-one desktop printer today. Found some 'shiny' stuff but not sure what some of them are. The sides and bottom of the printer are some kind of metal...tin...steel? No idea. There are some metal rods also...appear to be steel...are magnetic and shiny. What type of steel would these qualify as? And something real shiny and flimsy...looks like maybe tin. any ideas? Also found some copper in a little motor...what would be the best way to get it out? Wish I could post the pictures, thanks.
