High Purity Titanium Parts
The High Purity Titanium Parts produced by China Super Tech Co., Ltd. are made from high-purity sponge titanium. They are melted in a dedicated EB furnace to achieve a stable titanium purity of 4N5 to 5N level, with the oxygen content strictly controlled within 300 ppm. The products have low impurities and uniform performance, meeting the demanding requirements of high-end scenarios such as semiconductors, medical fields, and precision manufacturing. They are an ideal choice for high-reliability working conditions.
- Product Introduction
Product Features
1. Low Impurity Control Process: Using the exclusive Kroll process to prepare high-purity spongy titanium as the base material, the entire process is completed under vacuum protection through electron beam melting. The total amount of iron, nickel, chromium and other metal impurities is controlled within 28 ppm, avoiding the brittleness problem caused by common impurity segregation in ordinary titanium materials.
2. Low Oxygen Content Stabilization Technology: From melting to forming, the entire process is isolated from air, and the oxygen content is stable at less than 300 ppm, which is 40% lower than the oxygen content of conventional high-purity titanium components, significantly improving the ductility and fatigue life of the components.
3. Uniform Microstructure Treatment: Through directional solidification + multi-pass forging processes, the size difference of crystal grains within the component is controlled within 50 μm, avoiding local stress concentration and being less likely to crack or deform under long-term high-frequency vibration conditions.
4. Non-Magnetic Safety Attribute: The titanium purity reaches over 99.995%, completely eliminating the interference of ferromagnetic impurities, and will not cause signal offset problems in precision instruments and nuclear magnetic resonance supporting scenarios.
Product Application
1. Semiconductor sputtering target substrate: The extremely low impurity content can prevent particle contamination during wafer coating, ensuring the uniformity of the film on DRAM and other storage chips, and reducing the loss of chip yield.
2. Medical implant accessory components: The material is non-toxic and has excellent biocompatibility. After being implanted in the human body, it will not cause rejection reactions, and will not release harmful ions in the body fluid environment for a long time. It is suitable for the core structural components of orthopedic implants and dental implants.
3. Precision instrument moving parts: It is 3.5 times stronger than stainless steel, and under the same load, the weight of the component is reduced by 40%, effectively reducing the motion load of precision automation equipment, improving the equipment operation accuracy and response speed.
4. Chemical corrosion key accessories: The naturally formed dense oxide film on the surface can withstand long-term corrosion by seawater, dilute acid, and alkali media. Its service life is more than 8 times that of ordinary stainless steel components, reducing the frequency of maintenance and downtime of chemical equipment.
Customized Services
China Super Tech Co., Ltd.'s customized services are based on its own complete production chain. From raw material melting to finished product processing, all stages are independently controlled. Compared with the industry's outsourcing model, it can achieve targeted regulation of purity and oxygen content, avoiding impurity contamination caused by third-party processing. It supports customers in providing PDF/CAD drawings, adjusting the shape, tolerance and surface condition of components as needed. The tolerance can be stably controlled within ±0.01mm. At the same time, it can provide material inspection reports, and each batch of products comes with optional third-party testing certificates from SGS/TÜV. Small batch research orders and large batch industrial orders can be responded to quickly. Standardized customized parts can be delivered within 7-10 days. There is an exclusive technical contact person to monitor the progress in real time. It can also provide free material selection and processing optimization suggestions based on the actual working conditions of the customers, helping them reduce subsequent assembly and usage costs.

FAQ
What purity level is recommended for semiconductor and vacuum applications?
+
-
For semiconductor, vacuum, and ultra-clean processing equipment, high purity titanium with a purity of 99.9% to 99.995% is typically recommended. Higher purity minimizes metallic impurities, reduces outgassing, and lowers the risk of particle contamination during high-vacuum or high-temperature processes. The required purity depends on the application, with semiconductor fabrication often demanding 4N (99.99%) or 4N5 (99.995%) titanium.
How do you prevent contamination during the machining of high purity titanium parts?
+
-
High purity titanium requires dedicated machining equipment, contamination-free tooling, precision cleaning, and cleanroom-compatible handling. After machining, parts are typically ultrasonically cleaned, passivated if required, and vacuum packaged to prevent fingerprints, machining residues, and airborne particles from affecting product performance.
Can high purity titanium parts be manufactured with tight tolerances?
+
-
Yes. High purity titanium can be precision CNC machined into complex components with tolerances as tight as ±0.005 mm or better, depending on the part geometry. Manufacturers commonly provide CMM inspection reports, full dimensional verification, and material traceability to ensure compliance with demanding semiconductor, aerospace, and scientific equipment requirements.
Why are high purity titanium parts more expensive than standard titanium components?
+
-
The higher cost comes from the use of ultra-high purity raw materials, strict impurity control, specialized machining processes, contamination-free production environments, and comprehensive quality inspection. In addition, limited material availability and stringent packaging requirements contribute to longer production times and higher manufacturing costs.
What quality documents should suppliers provide for high purity titanium parts?
+
-
Reliable suppliers should provide a Material Test Certificate (MTC), chemical composition report, dimensional inspection report, CMM report (if applicable), surface roughness report, and full material traceability. For semiconductor and vacuum applications, some customers also require trace impurity analysis, helium leak testing, or cleanroom packaging certification to ensure the components meet ultra-high purity standards.
