TitaniumTitanium has superior structural integrity and is three times stronger than steel. Titanium is very light weight (1/3 as much as gold). Although a very hard and durable metal, titanium can still be scratched by abrasive materials like rocks or hardened steel tools. Titanium also plays a role in gems. Traces of titanium dioxide impurities cause the asterism phenomenon in Star Sapphires and Rubies. Blue sapphires can get their blue color from traces of titanium as well.
