Is the drawing asking for commercially pure titanium or an alloy?
Keep Grade 2, Grade 5 and Grade 23 distinct before discussing geometry. Grade 23 carries an ELI designation; a generic “titanium” description loses that requirement. OUJI has machined titanium alloys, while the particular grade, product form and certificate remain order-specific.
01 / MATERIAL SPECIFICATION
Titanium grades & conditions.
Match the full designation on your drawing. Frequent machining experience, published project evidence and specifications for review are shown separately.
| Grade / designation | Experience | Include with your drawing | Inquiry |
|---|---|---|---|
| Grade 2 | Specify for review | Grade 2: identify the commercially pure titanium product specification and stock form. | Quote grade ↗ |
| Grade 5 / Ti-6Al-4V | Specify for review | Grade 5 / Ti-6Al-4V: retain the required specification and annealed or other supplied condition. | Quote grade ↗ |
| Grade 9 | Specify for review | Grade 9: state the product form, especially when a tube specification rather than bar stock is required. | Quote grade ↗ |
| Grade 23 ELI | Specify for review | Grade 23 ELI: preserve the ELI requirement and the exact material document called for by the drawing. | Quote grade ↗ |
OUJI machining experience: confirmed by the company owner, 10 September 2026. Family-level experience does not establish a specific grade, stock condition or customer end use; see individual row and case evidence.
Listed grades do not imply current inventory. Material condition, stock form and documentation are agreed with the quotation.
02 / MACHINING REQUIREMENTS
Make the drawing ready for review.
Focus on the details that change material purchasing, the machining route and finished-part acceptance.
Thin sections and final clamping
Identify the surfaces used to locate the part and the features that must remain aligned after release from the fixture. Include the inspection datum scheme with the model.
Surface condition at delivery
Define whether as-machined surfaces are acceptable and identify contact or sealing faces. A material certificate alone does not specify finished roughness or surface cleanliness.
ORDER DETAILS
Material, finish and documentation.
Specify the requirements together so the quoted scope matches the finished part you need.
Purchasing
Material certificates ↗
Specify the material records and traceability your order needs.
ManufacturingFinish compatibility ↗
Connect material, coating and final dimensional requirements.

Review regional names without assuming an automatic substitute.
Finishing is coordinated through specialist partners. View surface finishing services.
Can Grade 5 replace Grade 23 ELI?
Do not assume it. Keep the ELI designation and applicable product specification in the order; any alternative requires the buyer’s technical approval.
Does titanium machining imply medical or aerospace certification?
No. A material-family machining history does not establish certification for an end-use industry. Provide the actual product specification and documentation requirements so the order scope can be reviewed.
