Product Detail
Product Introduction
Titanium Hollow Bar is thick-wall hollow machining stock selected when its section geometry reduces machining, improves material yield or supports the finished component design. Grade, dimensions, tolerances, condition and manufacturing route must be confirmed for the required section.
Product Specifications
| Product | Titanium Hollow Bar | Grade | Titanium Grade 2, Grade 5 or specified alloy |
|---|---|---|---|
| Standard | Approved seamless tube, forging or customer specification may govern the ordered product where its scope covers the grade and section. Special hollow stock or nonstandard sections may require an approved forging, seamless-tube or customer specification and inspection plan. | Size & Form | Thick-wall hollow machining stock by exact section dimensions, length and cut-to-size requirements |
| Tolerance | Applicable product specification or order-defined section, straightness, twist/camber, length, corner and surface tolerances | Supply Condition | Hot worked, cold worked, annealed, ground, peeled or machined as agreed, in protected bundles or export cases |
| Inspection | MTC and heat traceability, section dimensions, length and straightness, twist or camber where applicable, surface and ends, dimensional mapping, PMI or ultrasonic testing when specified. | Documents | MTC, heat/lot traceability and agreed inspection reports |
Additional Supply & Ordering Details
Useful, technically consistent information consolidated from earlier product pages.
| Product-form boundary | Titanium hollow bar is thick-wall annular machining stock ordered by outside diameter, inside diameter and wall. It is selected to reduce core removal for bushings, sleeves and rings and is not automatically pressure-service pipe or heat-exchanger tube. |
|---|---|
| Dimensional definition | State OD, ID, minimum and nominal wall, eccentricity, length, straightness, end condition, surface, machining allowance and finished-part envelope. |
| Supply-route decision | Forged-and-bored, trepanned, extruded, rolled-ring or other approved hollow-stock routes can have different grain flow, wall distribution and NDE coverage. Record the route and source specification. |
| Applications and inspection | Hollow bar supports sleeves, bushings, bearing carriers and annular machined parts. Inspect OD, ID, wall mapping, eccentricity, straightness, surface, UT when required and heat traceability. |

Services We Can Provide
Product Packaging
Bars and rods are separated by grade and heat, protected against surface damage and secured in bundles or export cases with identification and traceability labels. Typical export packaging for the same physical product form is shown below; final packing is confirmed for each order.
Application Scenarios
Machined rings, sleeves, bushings and components requiring reduced material removal
Material grade, dimensions, condition and inspection must be matched to the application requirements.
Aerospace, marine and chemical equipment
Material grade, dimensions, condition and inspection must be matched to the application requirements.
CNC-machined custom titanium components
Material grade, dimensions, condition and inspection must be matched to the application requirements.
FAQ
Why order a shaped titanium bar instead of round bar?
A near-net section can reduce machining time and material removal when its tolerances and availability suit the finished part.
Does one standard cover every titanium bar shape?
No. Confirm that the invoked specification covers the grade, section and manufacturing route; special hollow or custom sections may use another approved specification.
What information is required for quotation?
Provide grade, specification, section dimensions and tolerances, length, quantity, condition, surface, tests and certificates.
