Nature of titanium Aerospace titanium castings

Titanium steel appearance is very similar to a density of 4.51 g / cm 3, 60% less than steel, a refractory metal is Aerospace titanium castings the lowest density metal element. Titanium in air at room temperature is stable. When heated to 400 ~ 550 ℃, in the surface layer of a solid oxide film from the protective effect of preventing further oxidation. Titanium absorb oxygen , Nitrogen, hydrogen, strong ability of such gases are extremely harmful to the titanium impurities, even in extremely small amounts (0.01% to 0.005%) can seriously affect its mechanical properties. Mechanical titanium precision casting properties of titanium that is known mechanical properties is associated with purity. High pure titanium has excellent machining performance, elongation, reduction rate is good, but the low-intensity, discomfort cooperation knot Constitutive material. Containing an appropriate amount of an impurity of commercially pure titanium, having high strength and plasticity suitable for producing structural materials. In the titanium compound to the titanium dioxide (TiO2) is most practical. Ti02 on the human body is inert, non-toxic, it has a series of excellent optical properties. Ti02 opacity, gloss And white high refractive index and scattering force, hiding power, good dispersion,aerospace castings  pigments made from white powder, commonly known as titanium dioxide, wide application.
