Titanium has the following advantages

Titanium has the following advantages:
① high specific strength (tensile strength / density), a tensile strength of up to 100 ~ 140kgf / mm2, and the density of only 60% of steel.
② temperature strength, operating temperature of several hundred degrees higher than aluminum, at moderate temperatures can still maintain the desired strength, long-term work at a temperature of 450 ~ 500 ℃.
③ good corrosion resistance, Titanium heat exchanger surface immediately in the atmosphere to form a layer of uniform dense oxide film, the ability to resist the erosion of a variety of media.
④ low temperature performance, low interstitial elements of titanium, at -253 ℃ still maintain a certain plasticity.
⑤ low elastic modulus, low thermal conductivity, no ferromagnetism.
