Titanium extension spring with aircraft approved finish and coating

Titanium is one of the strongest metallic elements, having the highest strength-to-weight ratio of any metal. With its high strength-to-weight ratio, Titanium is as strong as some steels but is almost 50% lighter. With these characteristics, Titanium springs are one of the strongest and most weight-sensitive springs available. Not only are titanium springs exceptionally strong, they are also corrosion resistant. Titanium springs are used in many industries and in many applications, from motor bikes and race cars to aircrafts.

  • Weight Reduction
    The most widely recognized reason to use titanium over steel in a spring application is to lower the overall weight of the end product. Titanium springs can routinely weigh anywhere from 40-60% less than a steel spring used in the same application.
  • Free Length / Pitch Angle
    While most of the weight reduction from using titanium is built into the weight properties of the material itself, the lower torsion modulus of titanium also makes it possible to achieve the same load capacity in a shorter spring design by allowing for a steeper pitch angle on each coil.
  • Corrosion Resistance
    The basic metallurgical properties of titanium allow for a greatly improved resistance to corrosion, thus eliminating the need for costly plating and painting operations that are typically added to alloy steel spring designs.
  • Processing
    While titanium springs are different from traditional steel springs in many ways, it is possible to employ similar post production shot-peening and heat treatment processes to provide greater strength and increase the fatigue life of a titanium spring design.
