COEFFICIENT OF THERMAL EXPANSION
Titanium has the lowest coefficient of thermal expansion of all architectural metals. At 8.4 x 10-6, it is virtually equal to glass, concrete, brick and stone, making it highly compatible with these materials. This gives titanium an advantage over other metals in the design details of architectural projects. A typical standing seam roof will require periodic transverse seams. Titanium can be rolled into a continuous panel along the full length of a roof without transverse seams. Consequently, thermal stress on titanium is very low – typically half that of stainless steel and one-third that of aluminum.
