Select the titanium family before reviewing the part.
Commercially pure titanium and alloyed titanium serve different combinations of corrosion resistance, strength and formability. Choose a grade and product specification, then review the geometry and required records.
Corrosion-led components
State the medium, temperature and joining requirements. A commercially pure grade may be a candidate when strength is not the dominant constraint.
Lightweight loaded parts
Mark the load path, interfaces and fatigue-sensitive details. Use the specified alloy and condition rather than a general titanium label.
Traceability-led projects
Identify the governing material and process requirements at quotation. Industry use of titanium does not establish approval for an individual part.
Choose the grade and stock together.
Compare the Titanium options below against the drawing and service conditions. Specify the complete supplier grade, condition and stock form; material examples do not establish current inventory or permit substitutions.
| Grade or stock | Why consider it | What to resolve |
|---|---|---|
| Grade 2 / UNS R50400 | Corrosion- and ductility-led components using commercially pure titanium. | Specify stock form, condition, governing standard and actual chemical exposure. |
| Grade 5 / Ti-6Al-4V | Strength-led components with a specified alpha-beta alloy. | Retain the ordered condition and inspection or surface-integrity requirements. |
| Grade 9 / Ti-3Al-2.5V | A design already calling for this alloy, often in a particular product form. | Confirm the exact stock specification and whether machining is primary or a secondary operation. |
| Application-specific titanium | A drawing with a named specialty or controlled-grade requirement. | Provide the exact designation and approvals; do not infer implant or aerospace suitability. |
Selection examples are subject to material and drawing review. They are not an inventory list.
Already have a grade on the drawing?
Add it to your quotation checklist ↓Plan the tooling access and the surface that remains.
Show thin walls, deep pockets and small threads early. Material cost and geometry make it useful to resolve machining and acceptance requirements before stock is committed.
Heat and engagement
Review tool access, stable cutting and chip evacuation. A difficult deep feature may need a geometry or process discussion rather than an unsupported tolerance promise.
Thin-wall movement
Identify unsupported sections and final inspection conditions. Explain which dimensions control assembly and which faces may be held during machining.
Surface integrity
Specify burr limits, finish and contamination controls where the application needs them. Avoid leaving critical edges to a generic cosmetic note.
Mark critical dimensions on the drawing. Achievable tolerances, wall thickness, part size and delivery are confirmed for the geometry, material, finish and quantity in the quotation.
Choose the surface for function and acceptance.
As-machined
Define roughness, burrs and handling or cleaning requirements. Mark contact faces and fatigue-sensitive transitions.
Blasting or polishing
Specify media, finish direction and permitted material removal. Distinguish visible faces from sealing or fitted surfaces.
Coating or anodic colour
Name the required process, function and acceptance. Decorative colour alone does not establish wear resistance or application compliance.
Tie the delivered part to its titanium specification.
Material records
Identify grade, stock standard, heat or lot traceability and the exact certificate required.
Dimensional evidence
Mark datums, fitted features and inspection after any finishing. Agree the report scope and format.
Application-specific checks
State any additional material, process or surface tests with the RFQ. Medical or aerospace requirements require the actual applicable evidence.
Three different checks.
The material record identifies the purchased stock. The inspection report checks the drawing. Application validation checks the part in service.
Review inspection requirements ↗Titanium machining questions.
Answers to the decisions that affect the material, drawing and finished part.
Can Grade 2 replace Grade 5?
No automatic substitution is appropriate. They have different compositions and mechanical characteristics. The design owner should compare and approve the complete requirements.
Does titanium automatically mean medical grade?
No. The exact grade, stock specification, process controls and application approvals must be identified. A material family name is insufficient.
Why discuss thin walls before quoting?
Clamping, heat and tool engagement affect a slender section. Early review helps align geometry, machining sequence and the final inspection condition.
Can anodic colour identify the titanium alloy?
No. Appearance is not a material certificate. Use the specified purchasing records and any suitable agreed identification method.
Should a prototype use the production titanium grade?
Use the production specification when the test depends on its material behaviour. A geometry-only prototype can have a different purpose, but it should be identified as such.
What information helps quote titanium machining?
Include the grade and stock standard, condition, quantity, model and drawing, critical features, surface requirement and required traceability or tests.
Prepare your enquiry
Review the titanium specification before committing stock.
Send the CAD model and dimensioned drawing with quantities, service conditions and the requirements below. If the grade is undecided, describe the function and the constraints.
Your files stay confidential. NDA available.

Material references & specification notes
Manufacturer information supports material selection. Use the datasheet for the exact grade, stock form and test conditions. It does not establish Prolean inventory, application approval or a guaranteed machining result.
