What's The Density Of Titanium?

Titanium metal has ten properties:

1. Low density and high specific strength: the density of titanium is 4.51g/cm3, higher than aluminum and lower than steel, copper and nickel, but the specific strength is higher than aluminum alloy and high strength alloy steel.

2. Low elastic modulus: the elastic modulus of titanium at room temperature is 106.4Gmpa, 57% of that of steel.

3 small thermal conductivity: the thermal conductivity of titanium is small, is one fifth of low carbon steel, one twenty-five of copper.

4. Tensile strength is close to its yield strength: this property of titanium shows that its flexural strength ratio (tensile strength/yield strength) is high, indicating that the plastic deformation of metallic titanium material is poor during forming. As the ratio of yield limit to elastic modulus of titanium is large, the resilience of titanium is large.

5 non-magnetic, non-toxic: titanium is a non-magnetic metal, it will not be magnetized in a large magnetic field, non-toxic and has a good compatibility with human tissues and blood, so it is used by the medical community.

6. Strong anti-damping performance: titanium metal has the longest vibration attenuation time compared with steel and copper metal after mechanical and electrical vibration. The properties of titanium can be used for tuning forks, vibrating components of ultrasonic shredders in medicine and vibrating film of advanced audio speakers. The third generation titanium steel optical magnetic DVD system is also shockproof.

7 good heat resistance: the new titanium alloy can be used at 600℃ or higher temperature for a long time.

8. Good low temperature resistance: Titanium alloys TA7 (Ti-5Al-2.5Sn),TC4(Ti-6Al-4V) and Ti-2.5Zr-1.5Mo are represented by low temperature titanium alloys, whose strength increases with the decrease of temperature, but the plasticity changes little. Keep good ductility and toughness at low temperature of -196-253℃, avoid metal cold brittleness, is the ideal material for low temperature containers, storage tanks and other equipment.

9 suction performance: Titanium is a very active metal, can react with many elements and compounds at high temperature. Titanium inhalation mainly refers to the reaction with carbon, hydrogen, nitrogen and oxygen at high temperature.

10 corrosion resistance: Titanium is a very active metal, its balance potential is very low, in the medium of thermodynamic corrosion tendency. But in fact titanium in many media is very stable, such as titanium in oxidation, neutral and weak reducing media is corrosion resistant. This is because titanium and oxygen have a great affinity, in the air or oxygen containing medium, titanium surface generated a layer of dense, strong adhesion, inert large oxide film, protect the titanium matrix from corrosion. They heal or regenerate quickly even due to mechanical wear. This indicates that titanium is a metal with a strong passivation tendency. The titanium oxide film always maintains this characteristic when the medium temperature is below 315℃
