1. What manufacturing processes does VMT use for Grade 2 titanium?
CNC machining is our primary process for Grade 2 titanium parts, including 3-axis and 5-axis milling as well as CNC turning for prototypes and production runs. When a design involves complex geometries, internal features, or higher production volumes, titanium investment casting can be considered to reduce machining time and material waste. Our engineering team helps evaluate the most suitable process based on part requirements, tolerance needs, and production goals.
2. What surface treatment works best for Grade 2 titanium parts?
It depends on the application. Passivation works well for parts that need extra surface cleanliness, especially after contact with machining tools. Anodizing is a common choice when parts need color coding or a specific appearance. Our Grade 2 titanium CNC machining team can recommend the right option based on your drawing and end use.
3. Is Grade 2 titanium suitable for parts exposed to seawater or industrial chemicals?
Yes, Grade 2 titanium’s natural oxide layer gives it strong resistance to seawater and many industrial chemicals, making it a common choice for marine hardware and chemical processing equipment. As part of our Grade 2 titanium CNC machining service, we can also recommend passivation when additional surface cleanliness or contamination control is required.
4. What are the limitations of Grade 2 titanium?
Grade 2’s main limitation is lower strength compared with Grade 5 titanium, making it less suitable for parts with high structural loads or demanding mechanical requirements. For applications where the material choice is not clear, our engineers can review your design requirements, operating conditions, and load expectations to help determine whether Grade 2 is the right fit before production. This helps avoid specifying a higher-strength titanium grade when Grade 2 already meets the application requirements.
5. Do you offer a DFM review before quoting Grade 2 titanium parts?
Yes, every drawing goes through a free DFM review before quoting, checking for issues like thin walls, deep pockets, or tight tolerances that could affect cost or manufacturability. This is included in our Grade 2 titanium CNC machining service at no extra charge, so problems are caught early instead of after production starts.
6. Do you offer assembly services for Grade 2 titanium parts?
We primarily focus on CNC machining titanium components, but we can support basic assembly for multi part orders on request. For more complex assembly requirements, it’s best to walk through your project with us directly during quoting so we can confirm what’s feasible.
7. Can you sign an NDA before sending my drawing?
Yes, we’re glad to sign an NDA before reviewing your drawing. Every design is handled confidentially and shared only with the engineers directly involved in your project, whether or not an NDA is in place.
8. How long does it take to get a quote for Grade 2 titanium parts?
Most quotes for Grade 2 titanium CNC parts are sent within 24 hours of receiving your drawing. More complex projects with multiple parts or custom surface treatments may take slightly longer, but we’ll let you know upfront if that’s the case.
9. What’s the difference between Grade 2 and Grade 5 titanium?
| Grade 2 | Grade 5 |
|---|
| Tensile Strength (Ultimate) | 345 MPa | 950 MPa |
| Yield Strength | 275 MPa | 880 MPa |
| Machinability | Easier to machine | More difficult to machine |
| Typical Use | Corrosion resistant, non structural parts | High strength structural parts |
If your part doesn’t carry structural load, Grade 2 is usually the better choice, it machines faster, costs less, and still holds up well in corrosive environments. Grade 5 is worth the added cost only when your design genuinely needs the extra strength. For a full breakdown of when to choose each grade, see our detailed Grade 2 vs Grade 5 titanium comparison guide.
10. Do you provide mill test certificates (MTC) for Grade 2 titanium parts?
Yes, a mill test certificate is provided with every order of Grade 2 titanium CNC parts, confirming the material’s chemical composition and mechanical properties. Certificates of Conformity and inspection reports are also available on request.
