Ten characteristics of titanium

◆ low density and high specific strength: the density of metal titanium is 4.51g/cm3, which is higher than aluminum and lower than steel, copper and nickel, but the specific strength is the first among metals.

◆ corrosion resistance: titanium is a very active metal, its equilibrium potential is very low, and the thermodynamic corrosion tendency in the medium is large. But in fact, titanium is very stable in many media, for example, titanium is corrosion resistant in oxidizing, neutral and weak reducing media.

◆ good heat resistance: the new titanium alloy can be used at 600 ℃ or higher for a long time.titanium sheet grade4 price - TIRONG TECH

◆ good low temperature resistance: low temperature titanium alloys such as titanium alloy TA7 (ti-5al-2.5sn), TC4 (Ti-6Al-4V) and ti-2.5zr-1.5mo, etc., have strength increased with the decrease of temperature, but the plasticity has little change. It maintains good ductility and toughness at low temperature of - 196-253 ℃ and avoids metal cold brittleness. It is an ideal material for cryogenic vessels, storage tanks and other equipment.

◆ strong anti damping performance: compared with steel and copper, titanium has the longest vibration attenuation time after mechanical and electrical vibration.

◆ non magnetic and non-toxic: titanium is a non-magnetic metal, which 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 industry.

◆ the tensile strength is close to its yield strength: this property of titanium indicates that its yield strength ratio (tensile strength / yield strength) is high, which indicates that the plastic deformation of metal titanium material is poor during forming. Because the ratio of the yield limit to the elastic modulus of titanium is large, the resilience of titanium during molding is large.

◆ good heat exchange performance: Although the thermal conductivity of titanium metal is lower than that of carbon steel and copper, the wall thickness can be greatly reduced due to the excellent corrosion resistance of titanium. Moreover, the heat exchange mode between the surface and steam is droplet condensation, which reduces the heat group. The thermal resistance can also be reduced without scaling on the surface, so that the heat exchange performance of titanium can be significantly improved.

◆ low elastic modulus: the elastic modulus of titanium is 106.4gmpa at normal temperature, which is 57% of that of steel.

◆ gettering performance: titanium is a metal with very active chemical properties. It can react with many elements and compounds at high temperature. Titanium gettering mainly refers to the reaction with carbon, hydrogen, nitrogen and oxygen at high temperature.
