Ten key properties of titanium: 1. Titanium has a low density and high specific strength: Its density is 4.51, which is higher than that of aluminum but lower than that of steel; it is only half as dense as steel. Titanium’s strength ranks first among metals. 2 Titanium has strong corrosion resistance: Titanium is a very reactive metal with a low equilibrium potential, resulting in a high thermodynamic tendency to corrode in media. But in reality, titanium is very stable in many media; it is corrosion-resistant in oxidizing, neutral, and weakly reducing media. 3 Titanium has good heat resistance: titanium alloys can be used for extended periods at temperatures of 600°C or higher. 4. Titanium has good low-temperature resistance: Low-temperature titanium alloys such as TA7 and TC4 exhibit an increase in strength as the temperature decreases, while their plasticity remains relatively unchanged. It maintains good ductility and toughness at low temperatures of -196 to -253°C, avoiding metal cold brittleness; it is an ideal material for equipment such as low-temperature containers and storage tanks. 5 Titanium has strong anti-damping properties: When subjected to mechanical or electrical vibrations, titanium exhibits the longest vibration decay time compared to metals such as steel and copper. 6 Titanium has the properties of being non-magnetic and non-toxic: It is a non-magnetic metal that does not get magnetized even in strong magnetic fields; it is also non-toxic and exhibits good compatibility with human tissues and blood, which is why it is used in the medical field. 7 The tensile strength of titanium is close to its yield strength: this property of titanium indicates a high yield ratio (tensile strength/yield strength), suggesting that titanium metal has poor plastic deformation capacity during shaping. The high ratio of titanium’s yield limit to its elastic modulus results in a high springback capacity during titanium forming. 8 Titanium has excellent heat transfer properties: Although the thermal conductivity of titanium metal is lower than that of carbon steel and copper, its superior corrosion resistance allows the wall thickness to be reduced. Moreover, the heat transfer between the surface and steam occurs through droplet condensation, which reduces heat losses; the absence of scaling on the surface also lowers thermal resistance, thereby significantly improving titanium’s heat transfer capabilities. 9 Titanium has a low elastic modulus: at room temperature, titanium’s elastic modulus is 106.4 GMPa, which is 57% of that of steel. 10 Titanium has adsorption properties: Titanium is a metal with highly reactive chemical properties, and it can react with many elements and compounds at high temperatures. Titanium absorption mainly refers to the reaction with carbon, hydrogen, nitrogen, and oxygen at high temperatures.
