This is a material with a higher mechanical strength, stiffness, heat and wear resistance than Ertalon 6 SA. It also has a better creep resistance but its impact strength and mechanical damping ability are reduced. Well suited for machining on automatic lathes. Please note that Ertalon 66 SA natural rods over dia. 150 mm are made from a modified polyamide 66 resin. Ertalon 66 SA natural (rods, plates) is available as a "Food Grade".
