GR5 titanium alloy is also known as TC4 titanium alloy, because of its heat resistance, strength, plasticity, toughness, formability, weldability, corrosion resistance, and biocompatibility are better, and become the flagship alloy of the titanium alloy industry, known as the "metal of the future", is a new type of structural material with the prospect of development. Titanium and its alloys have been widely used in many industrial sectors such as the chemical industry, petroleum, light industry, metallurgy and power generation.
Titanium resists corrosion and is harmless to humans. Therefore, it can be widely used in the medical and pharmaceutical industries. Titanium has good suction performance and is widely used in electronic vacuum technology and high vacuum technology. GR5 titanium alloy usage has accounted for 75% ~ 85% of all titanium alloys. Many other titanium alloys can be seen as modifications of ti-6al-4v alloys. Titanium and its alloys have many excellent properties such as lightweight, strong strength, strong heat resistance, and corrosion resistance.
Excellent properties of GR5 titanium alloy rod:
1. Low density, high intensity
Titanium has a density of 4.51g/ cm3, higher than aluminum and lower than steel, copper, and nickel, but has the highest specific strength of any metal.
2. Excellent corrosion resistance
Titanium is a very active metal with a low equilibrium potential and a high tendency of thermodynamic corrosion in the medium. But in fact, titanium is very stable in many media, such as titanium in oxidation, neutral and weak reduction and other media is corrosion resistance. This is because titanium and oxygen have a great affinity, in the air or in the medium containing oxygen, titanium surface formation of a layer of dense, strong adhesion, inert oxidation film, protect the titanium matrix from corrosion. Even mechanical wear and tear can quickly heal or regenerate. This indicates that titanium is a metal with a strong tendency to passivation.
3. Strong damping resistance
Compared with steel and copper, titanium has the longest vibration attenuation time after mechanical vibration and electric vibration. The performance of titanium can be used as a tuning fork, vibration component of ultrasonic crusher and vibration film of an advanced audio speaker.
4. Non-magnetic and non-toxic
Titanium is a non-magnetic metal, in a large magnetic field will not be magnetized, non-toxic and with human tissues and blood has good solubility, so it is used by the medical community.
5. Good heat resistance
The new type of titanium alloy at 600 ℃ or higher temperature for long-term use.
6. Good low-temperature resistance
Titanium alloy TA7(ti-5al-2.5 Sn), TC4(ti-6al-4v) and ti-2.5 Zr-1.5 Mo are cryogenic titanium alloys, whose strength increases with the decrease of temperature, but their plasticity does not change much. In - 196-253 ℃ low temperature keep the good ductility and toughness, avoid cold brittleness, the metal is a cryogenic vessel, tank, and other equipment ideal material.
7. The tensile strength is close to the yield strength
This property of titanium indicates that its ratio of buckling strength (tensile strength/yield strength) is high, indicating that the metal titanium material has poor plastic deformation during forming. Due to the large ratio between yield limit and elastic modulus of titanium, the resilience of titanium forming is large.
8. Good heat transfer performance
Although the thermal conductivity of titanium metal is lower than that of carbon steel and copper, due to the excellent corrosion resistance of titanium, so the wall thickness can be greatly reduced, and the heat transfer mode between the surface and steam is droplet condensation, reducing the heat group, the surface does not scale can also reduce the thermal resistance, so that the heat transfer performance of titanium significantly improved.
9. Inhalation performance
Titanium is a very reactive metal, which can react with many elements and compounds at high temperature. Titanium inhalation mainly refers to the high temperature and carbon, hydrogen, nitrogen, oxygen reaction.
10. Low modulus of elasticity
At room temperature, the elastic modulus of titanium is 106.4GPa, which is 57% of that of steel.
