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, as well as compounds of  industrial areas and is failure-proof in even more aggressive environments.  Because it is one of the most noble metals, the coupling of titanium with  dissimilar metals does not accelerate galvanic corrosion of the titanium. It is  also lighter and stronger than stainless steel, another commonly used metal  which does not hold up as well in saltwater. These properties make titanium  perfect for use in many applications. Especially in the racing world! 
                Uses are  being developed for titanium in the automotive/motorcycle after markets and  racing market. Engine parts such as connecting rods, wrist pins, valves, valve  retainers and springs, rocker arms and camshafts, to name a few, lend  themselves to fabrication from titanium, because it is durable, strong,  lightweight and resists heat and corrosion. While titanium initially may be  more expensive for these applications, designs that exploit its unique  characteristics yield parts that more than pay for themselves with better  performance and a longer life.
