In the field of automobiles, titanium found its first application within the engine parts of racing cars early in the 1980s. Since then, the range of applications for titanium has expanded to include its application in the muffler systems of super short-type bikes and limited models of high-performance cars. Because of its great strength and low density, combined with virtual immunity to corrosion in the automotive environment, titanium offers many attractions for use in automobile applications. Despite its advantages, however, titanium hasn’t yet found a widespread use because the automotive industry is very price sensitive. The cost of titanium is relatively higher than that for steel or aluminum alloys. However, for some applications titanium is attracting great interest. Production passenger automobile components which could benefit from using of titanium include engine valves, connecting rods and valve spring retainers, as well as valve springs. However, until recently the use of titanium in the family automobile had not progressed beyond the prototyped stage because of the high cost of titanium compared to competing materials. There are two major obstacles that must be overcome if titanium is to be used in high-volume production.
