Abstract:
The titanium alloy system offers a range of properties conducive to weight/space savings. These properties include high strength, low elastic modulus and low density, which uniquely suit them for spring applications. By utilizing titanium in various spring designs, suspension engineers can save up to 60% of the weight and 20-30% of the space for a comparable steel spring. The primary impediment to widespread titanium part production and use in the past was cost. A new low cost titanium alloy system designed specifically for suspension and drive train application has been tested and proved to limit this cost problem. Working with titanium in their suspension designs, engineers will save significant weight/space over comparable steel and aluminum components.
