Copper powder, titanium alloy composite powder formulated with chromium powder or iron powder, titanium alloy and a manufacturing method thereof which was used as a raw material

Titanium alloy scrap and titanium alloy ingots as the starting material, by the powder method, excellent titanium alloy powder quality, providing a titanium alloy material and its manufacturing method. The titanium alloy material hydrogenated and hydrogenated titanium alloy, ground and sieved, the copper powder in the titanium alloy powder obtained by the dehydrogenation, chromium powder, or one or added to the titanium alloy of two or more of iron powder to obtain a composite powder, a manufacturing method for obtaining a densified titanium alloy material by HIP treatment and HIP treatment, or a titanium alloy composite powder after encapsulation after CIP process. Further, the titanium alloy obtained by the production method composite powder and titanium alloy.
