21st Century Material Titanium is absolutely immune to environmental attack, regardless of pollutants. Where other architectural metals exhibit limited lifespan, titanium endures. It withstands urban pollution, marine environments, the sulfur compounds of industrial areas and is failure-proof in even more aggressive environments. Because it is the most noble metal, the coupling of titanium with dissimilar metals does not accelerate galvanic corrosion of the titanium.

Immunity to Environmental Attack Architectural titanium's unsurpassed corrosion resistance results from its stable, highly-adherent, protective surface oxide film. Because the metal is highly reactive and has a strong affinity for oxygen, the beneficial oxide film forms spontaneously when exposed to moisture or air. In fact, a damaged oxide film can generally restore itself instantaneously. Warranty of a Century Unlike any other architectural metal or building material, TIMET warrants its commercially pure architectural titanium, TIMETAL® 35A (ASTM265 Grade 1) for 100 years against through-wall corrosion. This warranty covers all normal atmospheric conditions and typical environments such as urban, marine, industrial, mountain, desert and tropics. Lowest Thermal Expansion Titanium's coefficient of thermal expansion is half that of stainless steel and copper and one-third that of aluminum. It is virtually equal to that of glass and concrete, making titanium highly compatible with these materials. Consequently, thermal stress on titanium is very low. Light Weight The specific gravity of titanium is 4.51 g/cm3 - about 60% that of steel, half that of copper and 1.7 times that of aluminum. Being such a lightweight metal, titanium imposes less burden on structure. It is easily fabricated and permits ease of installation. Environmentally Safe Due this its relative inertness in most atmospheres, titanium is considered environmentally friendly. It is 100% recyclable and the product of a renewable resource. Greatest Strength In addition to having excellent mechanical strength (comparable to mild steel), titanium is durable and shock resistant. Its modulus of elasticity (a measure of strain rate) is half that of stainless steel. This means titanium is more flexible than other architectural metals during earthquakes and other periods of violent movement. Best Energy Efficiency For a metal, titanium is an excellent insulator. Its thermal conductivity of 10 Btu/hr.-Fº/ft. is very low (one-tenth that of aluminum) increasing a building's energy efficiency.
