Titanium has a low density, about 60% of steel, 50% of copper, and 1.7 times that of aluminum, but it has almost the same strength as ordinary steel. As a building, it can reduce weight by 70% to 75%. It is easy to hoist and can make buildings. The center of gravity of the object is moved down to improve the overall earthquake resistance of the building. Titanium rod has good corrosion resistance: it can resist urban pollution, industrial radiation and extreme erosion. Titanium rod is easy to process into thin plates and has good welding performance. Titanium itself has a shiny silver-white luster, and through treatment, a brighter surface can be obtained. In order to achieve a more beautiful decorative effect, different patterns and colors can be obtained by etching and anodizing.
