CNC Milling
3, 4 and 5-axis CNC milling is highly flexible and accurate for manufacturing complex titanium parts with prismatic shapes, geometric cavities, and consistent tight tolerances.
CNC Turning
CNC turning is ideal for forming titanium bars, focusing on cylindrical parts with deep holes, threads, and an excellent surface finish. Ensure dimensional consistency.
Swiss CNC Machining
Swiss CNC Machining quickly and accurately manufactures extremely small and even complex titanium parts in large quantities. This includes milling, threading, drilling, boring, turning.
CNC Grinding
Grinding capabilities range from 0.1mm to 300mm diameter and 2mm to 1200mm length, with tolerances as tight as ±0.002mm and micro finishes as tight as 0.2 Ra.
CNC Drilling
CNC drilling is the process of cutting a hole using a sharp, rotating drill bit. When drilling holes in titanium, coolant is often used to reduce heat buildup, maintain accuracy, and extend tool life.
CNC Tapping
CNC tapping is the process of using a tap to cut threads in a drilled hole to allow a screw or bolt to be inserted. This is critical for components that require fasteners to be assembled.
5 Axis CNC Milling
5-axis CNC milling relies on the tool moving in five different directions – X, Y, and Z, as well as A and B, around which the tool rotates. 5-axis CNC milling saves time and is ideal for creating complex parts with high precision.
WEDM Machining
Wire EDM services are used to create high-quality, complex parts with tight tolerances. The process is ideal for creating parts with complex shapes, sharp corners, and delicate features that are not possible with traditional machining methods.
EDM Machining
EDM utilizes rapid pulsed high voltage discharges (sparks) across the gap between an electrode and a grounded workpiece to remove material from the workpiece by erosion to create structurally complex parts.
Production Capacity
Wstitanium has established a modern CNC machine shop, 45 3-axis, 4-axis, 5-axis CNC machining centers, including world-renowned brands (HAAS\DMG), CNC turning centers, CNC grinding, EDM, WEDM machining centers. Wstitanium knows that advanced equipment is the basis for manufacturing customized titanium parts. Of course, the manufacturing level of the machinist is still one of the most important factors. Therefore, monthly internal training and external further studies are the reasons why Wstitanium has mastered flexible manufacturing technology.
Common CNC Machining of Titanium Grades
Titanium (or Ti in the periodic table) is a lightweight metal with several useful properties, from corrosion resistance to strength retention at extreme temperatures. Titanium has an impressive strength-to-weight ratio and is 40% lighter than steel. This makes titanium an ideal material choice for high-tech industries such as aerospace, automotive, medical technology, and energy. It is available in both pure titanium and alloy forms. Pure titanium contains trace amounts (less than 1%) of iron and oxygen. Advanced titanium alloys significantly enhance the overall strength. Of these, grade 5 titanium, or Ti 6Al-4V, is the most popular titanium alloy.
| Grade | Hardness Rockwell 30T | Tensile Strength Ultimate | Tensile Strength, Yield | Elongation at Break | Tensile Modulus | Feature |
|---|---|---|---|---|---|---|
| Grade 1 Titanium | 70 HR30T | 240 MPa | 170 MPa | 24% | 105 GPa | High Corrosion Resistance |
| Grade 2 Titanium | 80 HR30T | 345 MPa | 275 MPa | 20% | 105 GPa | Excellent Strength-to-Weight Ratio |
| Grade 5 Titanium | 36-38 HR30T | 880 MPa | 830 MPa | 10% | 114 GPa | High Strength |
| Grade 9 Titanium | 80 HR30T | 900 MPa | 830 MPa | 15% | 118 GPa | Excellent Balance of Strength, Toughness, and Workability |
| Grade 23 Titanium | 40-45 HR30T | 860 MPa | 790 MPa | 10% | 114 GPa | High Biocompatibility |
Grade 1 & 2 Titanium is a soft and ductile alloy consisting of 99% titanium with trace amounts of other elements. It has high corrosion resistance and is preferred by the medical and dental industries for its excellent biocompatibility.
Grade 1 & Grade 2
Grade 3 Titanium commercially pure titanium is a non-alloyed, high-strength commercially pure titanium with excellent corrosion resistance and good weldability. This titanium is primarily used for airframe and aircraft engine components.
Grade 3
Grade 4 has a high titanium content and is the strongest of the four commercially pure titanium grades, with good formability and corrosion resistance. It is used almost exclusively in aircraft engine parts, ships, and surgical implants.
Grade 4
Grade 5 titanium alloy, or Ti6Al4V, is a popular titanium alloy for CNC machining due to its excellent properties and is one of the strongest titanium alloys available. Grade 5 is a common material choice for engine components and aircraft fuselages.
Grade 5
Grade 6 Titanium (Ti5Al-2.5Sn) 5% aluminum and 2.5% tin, has good strength, weldability and corrosion resistance due to the presence of tin. Suitable for chemical processing, marine engineering and aerospace, frames and jet aircraft.
Grade 6
Grade 7 titanium alloy is similar to grade 2 and contains 0.12% to 0.25% palladium, 0.3% iron, 0.25% oxygen, and some other elements. Grade 7 titanium is the most corrosion resistant among all titanium alloys. It is the most corrosion resistant in reducing acids.
Grade 7
Grade 9 titanium alloy consists of 2.5% vanadium and 3% aluminum and is an alpha-beta alloy. This titanium grade has a good balance of weldability, strength and corrosion resistance. This type of titanium metal is used in chemical processes, aerospace applications, sports equipment and biomedical devices.
Grade 9
Grade 11 titanium, also known as CP Ti-0.15Pd, contains 0.2-0.4% palladium. It has good ductility, impact toughness, and very high resistance to crevice corrosion. It is more ductile and less tolerant of other impurities. It is less strong than Grade 7 and is used in the maritime and chlorate production industries.
Grade 11
Grade 23 Titanium is also known as Ti-6Al-4V ELI. ELI stands for Extra Low Interstitial. Very similar to Grade 5, but Grade 23 titanium alloy has lower oxygen, nitrogen and iron content. Grade 23 titanium has better ductility and fracture resistance than Grade 5. Commonly used in chemical, medical, aerospace.
Grade 23

Finishing Services for Titanium
Surface treatments enhance the durability and aesthetics of custom titanium parts, adding additional protection against corrosion and wear. At Wstitanium, we offer a variety of surface treatment options based on your needs, ensuring your components achieve the desired look and functionality. They include polishing, anodizing, passivation, powder coating, sandblasting, and more. Each finish offers unique benefits, all ensuring your parts meet aesthetic and functional specifications.
As Machined
Titanium parts are removed from CNC machines to retain the machined surface, showing tool marks without additional processing. It is an economical choice. Ra<0.8
Anodizing
Anodizing of titanium parts, which gives them vibrant colors and enhanced corrosion and wear resistance, is often used in medical and decorative applications.
Sand Blasting
Sandblasting is suitable for titanium parts to give them a matte, textured effect. It enhances the wear resistance, corrosion resistance and fatigue resistance of titanium.
Polishing
Polishing is to remove flaws, oxide layers and burrs on the surface of titanium parts to make them smooth and bright, thus improving their appearance.
Electropolish
Electrolytic polishing can give titanium parts a bright reflective surface, enhance their smoothness, and improve their corrosion resistance. It is an environmentally friendly way.
Powder Coating
Titanium parts are powder coated with a thick, wear-resistant layer that offers outstanding color and texture. Coating has excellent corrosion resistance, wear resistance, hardness.
Electroplating
Electroplating bonds a thin metal layer to titanium parts, increasing surface hardness, wear resistance, corrosion resistance, oxidation resistance, improving its conductivity.
Brushed Finish
The brushed finish of the titanium parts creates a unidirectional satin texture, reducing the visibility of surface marks and scratches. Flatter and more beautiful.
