The superior properties of titanium glasses

They are light, around 40% of stainless steel. The hardness is high, about twice that of stainless steel and common steel, twice that of iron, and six times that of aluminum. In a world of ultra-low temperatures, titanium becomes harder and more superconductive, while steel becomes weaker and less capable. They have corrosion resistance, with no rust.
