Can Buildings Be Made Of Titanium?

Although "the people take food as the sky", they also need "tens of millions of spacious houses", isn't there a saying of "living and working in peace and contentment"? What is the joy of living in a unstable place? Where does karma come from?
Human habitation begins with caves and nests, and the changes in residence reflect social progress and social civilization. Thatched houses, bamboo and wood houses, mud houses, stone houses, brick houses, steel frame houses...... Now titanium has entered the construction field.

To understand why titanium is a material in construction, you must first know what titanium is?

Titanium is a chemical element with the symbol Ti and atomic number 22.
As a metal, titanium is lightweight, strong, and resistant to corrosion.
