In the titanium, including titanium, titanium rods, titanium tubes, etc., including both titanium and titanium alloy.
Titanium and titanium alloy is the most significant difference is that the titanium alloy is based on pure titanium, such as Al, Mo, Cr, Sn and other chemicals, Performance difference. This article focuses on the analysis of pure titanium in the classification, performance and use of the introduction. In the case of
1. pure titanium classification:
According to the impurity content, titanium is divided into high purity titanium (purity of 99.9%) and industrial pure titanium (purity of 99.5%). Industrial titanium has three grades, respectively, with TA + sequence number 1, 2, 3, the greater the number, the lower the purity. In the case of
2.the performance of pure titanium:
Ti: 4.507 g / cm3, Tm: 1688 ° C. With the same isomerization, ≤ 882.5 ℃ for the closed hexagonal structure of the α phase, ≥ 882.5 ℃ body cube cubic structure of the β phase. In the case of
Pure titanium low strength, but higher than the strength, good plasticity, low temperature toughness, corrosion resistance is high. Titanium has a good pressure processing performance, cutting performance is poor. Titanium can be heated in nitrogen to produce combustion, so titanium should be protected by argon during heating and welding. In the case of
3. the use of pure titanium:
Impurity content on the performance of titanium has a great impact on a small amount of impurities can significantly improve the strength of titanium, so the industrial pure titanium strength is high, close to the level of high-strength aluminum alloy, mainly for the production of 350 ℃ below the temperature of the petrochemical heat exchange Equipment, reactor, ship parts, aircraft skin and so on.
