Grade 1 Commercially Pure Titanium

Titanium is classified in two categories: commercially pure titanium (Ti) which is used in the chemical process industries and titanium alloys having such additives as aluminum (Al) and vanadium (V) and which are used for jet aircraft engines, airframes and other components.

Unalloyed and alloyed titanium have been used in medical engineering for many years. The applications are varied and include the following:

  • joint replacement parts for hip, knee, shoulder, spine, elbow and wrist,
  • bone fixation materials such as nails, screws, nuts and plates,
  • dental implants and parts for orthodontic surgery and dental prosthetics,
  • heart pacemaker housings and artificial heart valves,
  • surgical instruments for heart and eye surgery,
  • components in high-speed blood centrifuges.

Titanium has long been considered an exotic metal. In recent years there has been a progressive change in its image from an expensive curiosity to material much more familiar to consumers as it finds more commercial applications such as eyeglass frames, sports equipment, accessories and art.

Characteristics of Titanium

  1. It is lightweight with a specific gravity of 4.5, or around 50% that of copper and 60% that of iron.

  2. It is a strong material with a tensile strength comparable to carbon steels. With a Young's modulus only half that of carbon steel, titanium is soft and readily formed, with spring back greater than carbon steel's.

  3. It has excellent corrosion resistance to seawater providing long service in offshore and marine environments.

    Commercially pure titanium resistants corrsion from acid rain and is growing in popularity for architectural application. As a building material, titanium is free from pitting corrosion, crevice corrosion or stress corrosion cracking.

    Increasing attention as an environmentally friendly metal because it does not liberate toxic heavy metal ions by corrosion. Japan started using titanium as roofing and siding material in the early Nineteen Seventies. As an Island nation, Japan finds real benefits to the corrsion properties of titanium as a building material.

  4. It can be formed as easily as stainless steel.
    Other factors that contribute to its diversity of application include its low coefficient of thermal expansion, absence of magnetism, and color by anodizing.

    Titanium has a smaller thermal expansion and shrinkage than stainless steel. Titanium has a linear coefficient of thermal expansion approximately 50% that of stainless steel. Therefore, it will experience smaller changes in dimensions caused by thermal expansion and shrinkage.
