1. Low density and high specific strength
The density of titanium metal is 4.51g/cm3, which is higher than aluminum and lower than iron, copper, and nickel, but its specific strength is at the top of the metal;
2. Titanium is a very active metal, its equilibrium potential is very low, and it has a strong tendency to passivation;
3. Good heat resistance. The new titanium alloy can be used for a long time at a temperature of 600*C or higher;
4. Good low-temperature resistance. Its strength increases with the decrease of temperature, but its plasticity changes little. It maintains good ductility and toughness at low temperatures of -196-253*c. Avoiding the cold brittleness of metals, it is an ideal material for low-temperature containers, storage boxes, and other equipment;
5. Strong anti-dumping performance.
Titanium metal is subjected to mechanical vibration and electrical vibration. Compared with steel and copper metal, its own vibration decay time is the longest. This performance of titanium can be used for vibration of tuning forks, medical ultrasonic pulverizer vibration components, and high-end sound speakers. The film, etc.;
6. Non-magnetic and non-toxic. Titanium is a non-magnetic metal and will not be magnetized in a large magnetic field. It is non-toxic and has good compatibility with human tissues and blood, so it is adopted by the medical community;
7. The property that the tensile strength and its yield strength are close to that of titanium shows that its yield ratio (tensile strength/yield strength) is high, which means that the plastic deformation of the metal is poor informing, due to the yield limit of titanium and the elastic film The larger the ratio of the amount to the larger, the greater the resilience of the titanium during forming;8. Good heat transfer performance. Although the thermal conductivity of the metal state is lower than that of carbon steel and copper, due to the excellent corrosion resistance of titanium, the wall thickness can be greatly reduced when used, and the heat exchange method between the surface and the steam is dropwise condensation, reducing In addition to thermal resistance, the titanium surface can also reduce thermal resistance without scaling, and significantly improve the heat transfer performance of titanium.
9. Low modulus of elasticity: The modulus of elasticity of titanium is 106.4GMPa at room temperature, which is 57% of steel;
10. Gettering performance. Titanium is a chemically very active metal, which can react with many elements and compounds at high temperatures. Titanium getter mainly refers to the reaction with carbon, hydrogen, and oxygen at high temperatures.
