High Purity Titanium

Overview of High Purity Titanium

Titanium materials with a purity of 99.99% or even higher are called high-purity titanium. The standards for high-purity titanium are YS/T1236-2018 and ASTM F1709. In industry and scientific research, there are different purity standards according to different application requirements.The preparation methods of ultra-high-purity titanium include iodization, thermal reduction, electrolytic refining, and electron beam melting, etc.

The iodization method can be used to prepare ultra-high-purity titanium with a purity level of 6N and is expected to become the mainstream preparation method in the future.
High-purity titanium features excellent corrosion resistance, biocompatibility and high specific strength, etc.
During manufacturing, it requires special smelting and processing procedures to reduce the impurity content.

Ultra-high purity titanium can be used to produce high-end titanium alloys, and it has a strong demand in the fields of aerospace, electronics and electrical engineering, national defense and military industry, scientific research, and healthcare.

In the aerospace field, ultra-high purity titanium can be used to manufacture aircraft components; In the electronics and electrical field, it can be used to manufacture large-scale integrated circuits; In the defense and military industry field, it can be used in missile weapon systems and armor components; In the healthcare field, it can be used to manufacture surgical instruments and vascular stents, etc. Only ultra-high purity titanium can meet the raw material demands of numerous modern industrial and advanced processing technologies, such as sputtering target for semiconductor chips, high-end titanium alloys for aerospace applications， and high-end titanium powder for 3D printing.

Among various melting processes, electron beam melting (EB) products stand out due to their absence of internal defects and excellent impurity removal effect. The purity of titanium ingots produced by this method can reach 99.9995%, with oxygen content less than 0.01%. The maximum diameter of the ingot can reach 800mm. This large-diameter ingot enables more diverse subsequent deformation processing methods and significantly improves the yield of the processed products.
