There was an add on Craigslist for someone giving away a few old x-ray machines. They weren't sure if the machines worked or not, so i figured why not get them. After taking one apart, most of the metal is aluminum,lead,copper,some stainless steel and light iron. I did some looking online and found the anode for the x ray tube is probably made of molybdenum. Anyone else ever take one of these apart?
