Abstract
A lubricant includes at least 45 wt % paraffin oil, less than 8 wt % of a pyrophosphate or triphosphate, more than 6 wt % of a group 6 disulfide or diselenide and up to 27.5 wt % of graphite. The lubricant is used in a method for producing a magnesium alloy tube via extrusion, and is especially useful to form implants such as stents while maintaining the biocompatibility of the magnesium alloy.
