Product Detail
Product Introduction
TC4 Titanium Alloy Bar is supplied for corrosion-resistant fabrication and precision manufacturing. The final purchase definition must identify the exact material designation, governing specification and revision, dimensions, condition, tolerances, tests and documentation; trade-name or cross-standard equivalence is not assumed.
Product Specifications
| Product | TC4 Titanium Alloy Bar | Grade | TC4 / Ti-6Al-4V; exact specification and equivalence must be confirmed |
|---|---|---|---|
| Standard | GB/T or customer specification; ASTM B348 only when expressly ordered | Size & Form | Round bar, rod and cut blanks; diameter, length, straightness and machining allowance are confirmed by RFQ |
| Tolerance | Governing material standard or approved customer drawing | Supply Condition | Hot rolled, forged, annealed, peeled, pickled or ground as specified |
| Inspection | MTC review, dimensional and surface inspection, heat/lot traceability, with PMI or applicable NDT when specified | Documents | MTC, heat/lot traceability and agreed inspection reports |
Additional Supply & Ordering Details
Useful, technically consistent information consolidated from earlier product pages.
| Chinese grade boundary | This page targets TC4 titanium alloy bar ordered to the applicable GB/T, aviation or customer specification. TC4 is a Chinese Ti-6Al-4V-family designation, not an automatic ASTM or AMS certification. |
|---|---|
| Specification control | State the controlling Chinese standard and revision, delivery condition, section, dimensions, heat treatment, mechanical properties, test sampling, surface and NDE requirements. |
| Grade 5 relationship | ASTM Grade 5 / UNS R56400 and TC4 share a nominal alloy family, but standards can differ in product scope, condition, testing and acceptance. The required certificate system controls. |
| Procurement focus | Use this page when TC4 and Chinese-standard documentation drive the order. Request original material certificate, heat identity, chemistry, properties, dimensions and agreed inspection records. |

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
Chemical processing equipment
Material grade, dimensions, condition and inspection must be matched to the application requirements.
Marine and desalination systems
Material grade, dimensions, condition and inspection must be matched to the application requirements.
Industrial fabrication and precision components
Material grade, dimensions, condition and inspection must be matched to the application requirements.
FAQ
Is TC4 exactly the same as ASTM Grade 5?
They belong to the same nominal Ti-6Al-4V alloy family, but standard scope, condition, test methods and acceptance must be reviewed before claiming equivalence.
Which standard should be stated for TC4 bar?
Provide the applicable GB/T, aviation or customer specification and revision together with condition, dimensions, properties and tests.
When should the ASTM Grade 5 page be used instead?
Use it when the buyer requires ASTM B348, ASME SB348, AMS 4928 or UNS R56400 documentation rather than TC4/GB certification.
