Chemical and physical properties of titanium and titanium plate

Commercially pure titanium by impurity elements in three levels, namely, TA1, TA2, TA3. Commercially pure titanium is mainly used for high plasticity, adequate strength, good corrosion resistance and weldability of the occasion. Their good cold workability,tittanium bars can produce a variety of plates, rods, profiles, strips, tubes and foil. Sheet can be cold stamping. Three grades of commercially pure titanium were annealed delivery use.
1 Chemical composition of commercially pure titanium
GB The TA1, TA2 and TA3 This corresponds UNS in Gr0, Gr1 and Gr2.
TA1, TA2 in ω is 0.095% iron, 0.08% oxygen content of ω, ω is a hydrogen content of 0.0009%, 0.0062% nitrogen content of ω, the low temperature toughness and has good high temperature strength, can be used -253 ℃ below the low temperature structural materials.
TA2 Chemical composition: TA2 titanium (Ti) the balance of iron (Fe) ≤ 0.30, carbon (C) ≤ 0.10, nitrogen (N) ≤ 0.05, the hydrogen (H) ≤ 0.015, oxygen (O) ≤ 0.25.
2 Physical and chemical properties of commercially pure titanium
Density: the density of 4.51, which is about 1/2 gold, 1/4, cobalt-chromium alloy.
Thermal conductivity is low: only gold 1/17, therefore, can effectively protect the titanium porcelain dental pulp tissue from the outside of the hot and cold acid stimulation;
Line shrinkage: 1.75%, lower than the gold alloy and cobalt-chromium alloy, has excellent suitability for casting high precision.
     Non-magnetic titanium:titanium stockists Titanium is not magnetized in a magnetic field.
Titanium metal surface passivation film has a strong resistance to corrosion: Titanium in the natural environment is almost not exist alone, it will react with oxygen to generate passive film on the surface of titanium dioxide, which has strong corrosion resistance.
