Titanium performance

A new type of titanium alloy can be used for a long time at a temperature of 600 DEG C or higher temperature. Titanium alloy TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V) cryogenic titanium alloy and Ti-2.5Zr-1.5Mo as the representative, its strength increased with the decrease of temperature, but the plastic has hardly changed. Keep good ductility and toughness in the -196-253 degrees Celsius temperature, avoiding metal cold brittleness, is the ideal material for cryogenic vessel, tank and other equipment. Titanium sheet metal is affected by mechanical vibration, electric vibration, compared with steel and copper metal, its vibration attenuation for the longest time. The use of the properties of titanium can be used as a tuning fork, medical ultrasonic pulverizer vibrating element and high sound loudspeaker vibration film etc..
Titanium is non-magnetic metal, in a large magnetic field will not be magnetized, non-toxic and human tissue and blood compatibility good, so is the medical community by.
The performance of titanium tubing for sale shows its ratio of yield strength (tensile strength / yield strength) high, said metal titanium material in forming poor plastic deformation. The ratio of titanium yield limit and elastic modulus, the springback of titanium forming large. The coefficient of thermal conductivity of metallic titanium although than carbon steel and copper is low, but because of the corrosion resistance of Powder coating titanium excellent, so thin wall thickness can be greatly reduced, and the surface and the steam heat transfer mode for dropwise condensation, reducing the heat group, titanium surface scaling can also reduce the thermal resistance, so that the heat transfer performance of titanium significantly to improve the. The elastic modulus of titanium at room temperature for 106.4GPa, 57% for steel. Titanium is a chemically very active metals, react with many elements and compounds at high temperature. Titanium gettering mainly refers to the high temperature and carbon, hydrogen, nitrogen, oxygen reaction.
