there was a KFC store collecting the pull tabs off the coke cans , they were trying to get enough titanum to make a flase leg for a local girl . Absolutely sure on this? If you want to ask a metalworking question and get a real answer, take it to rec.crafts.metalworking. Im interested in the metal , The "Titanium" that you are interested in is really titanium steel. That is steel that has a fractional percentage of the element titanium, and probably other **** added. Like stainless steel is a steel with chrome and other stuff added to give it that "stainless" property. if pull tabs are a source , they are easy to get in big numbers. which would tell you that the metal is worth; **** extra how easy is it to melt and cast ? I have absolutely no idea. I thought the idea with titanium was that you roll or extrude a thinner cross section and save weight. OTOH, read a rule of thumb the other day (bicycle list) where someone said he just doubled the thickness of the aluminium he used, obtained the same strength and saved a third of the weight. |
