Has anyone seen or know if its even possible to make a cast platinum bar? My extensive Googleing has come up with nothing and I have spoken to 2 refiners who told me they left platinum in the dust a long time ago. Im looking for a picture or anything regarding a cast platinum bar. Thanks
Cheers OZ This was the only one i found but it looks like it wsa put through a roller or something. Or does Platinum cool that flat?
From Johnson-Matthey: "Platinum is usually considered to be a ductile workable metal readily fabricated by all the usual processes; it is therefore somewhat surprising to discover that the machining of platinum by conventional techniques results in rapid and extensive tool wear, with consequent deterioration of the surface finish imparted to the platinum article."
