Titanium and its alloy with low density, high specific strength, high and low temperature resistance, corrosion resistance, no magnetic, good biocompatibility, stable performance characteristics. The titanium alloy has the characteristics, but also has high precision in dimension, good surface quality, near net shape forming, processing and less or no processing capacity, has high production efficiency. Application of titanium castings can be greatly improved component performance and quality, and reduce cost, reduce weight, increase the utilization ratio of materials. The hot isostatic pressing and heat treatment, titanium alloy castings performance even close to the annealing of titanium alloy forgings for performance. Therefore, Ti alloy castings are widely used in aviation, aerospace, shipbuilding, chemical industry, metallurgy, energy, education, medical and other fields.
