Titanium properties, which are a combination of high strength, stiffness, tenacity, low density and good corrosion resistance from Titanium alloys from very low to high temperatures, allow for weight saving of Aerospace structures and other high applications performance.
The atomic weight of titanium is 47.88. Titanium is lightweight, strong, corrosion-resistant and abundant in nature. Titanium and its alloys have a tensile strength of 30,000 psi to 200,000 psi (210-1380 MPa), which are equivalent to the properties found in most of the steel alloys.
Titanium is a low density element (about 60% of iron density), which can be reinforced by alloying and transformation. Titanium is nonmagnetic and has good thermal transfer properties. Its thermal expansion coefficient is somewhat lower than that of steel and less than half that of aluminum.
One of the useful properties of Titanium is the very high melting point of 3135 ° F (1725 ° C). This melting point is approximately 400 ° F above the melting point of the steel and approximately 2000 ° F above the melting point of the aluminum.
Titanium may be passive, and thus exhibits a high degree of immunity to attack by most mineral acids and chlorides. Titanium is not toxic and is generally biologically compatible with human tissues and bones. Excellent corrosion resistance and bio compatibility coupled with its power to make Titanium and its alloys useful in chemical and petrochemical applications, marine environments and biomaterial applications.
Titanium is not a good conductor of electricity. If copper conductivity is assumed to be 100%, Titan would have a conductivity of 3.1%. It follows that Titan would not be used in applications where good conductivity is a primary factor. For comparison, stainless steel has a conductivity of 3.5% and aluminum has a conductivity of 30%.
Electrical resistance is the opposition that a material presents to the electron stream. Since titanium is a weak conductor, it results that it is a good resistor.
