Product Detail
Product Introduction
Source ASTM B863 Grade 2 titanium wire from 0.1–10 mm, with bright or pickled finish, inspection and material traceability. Final supply is controlled by the grade, specification revision, dimensions, condition, tolerance, inspection and documentation stated on the approved order.
How should Grade 2 titanium wire be specified?
Selection answer: Use ASTM B863 Grade 2 / UNS R50400 for specification-controlled product wire where commercially pure titanium corrosion resistance and forming characteristics are required. Define diameter, condition, delivery form and the finished component duty.
Selection boundary: Do not use Grade 2, ERTi-2 and implant-grade wire as interchangeable descriptions. Product wire, welding filler and surgical-implant material have different controlling standards and acceptance documentation.
RFQ data to confirm: Send the application, standard and revision, diameter and tolerance, condition, coil, spool or straight length, unit weight, quantity, inspection, cleanliness, marking and traceability requirements for RFQ review.
Product Specifications
| Product | Titanium Grade 2 Wire | Grade | Grade 2 commercially pure titanium / UNS R50400 |
|---|---|---|---|
| Standard | ASTM B863 covers titanium and titanium-alloy product wire and identifies Grade 2 as UNS R50400. State the required revision, diameter, tolerance, condition and delivery form. ERTi-2 welding wire or rod under AWS A5.16 / ISO 24034 is a separate filler-metal classification and must not be inferred from an ASTM B863 order. | Size & Form | Existing range includes 0.1–10 mm diameter; coil, spool or straight length by RFQ |
| Tolerance | Applicable ASTM B863 tolerance or customer drawing | Supply Condition | Bright or pickled surface; coil, spool or straight length |
| Inspection | Review the MTC and heat/lot identity, Grade 2 / UNS R50400 chemistry, mechanical results for the ordered condition, diameter and tolerance, surface, coil, spool or straight-length identity, cast and helix where applicable, unit weight, marking and package traceability. Define cleanliness, straightness or supplementary examination when the end use requires it. | Documents | MTC, heat/lot traceability and agreed inspection reports |

Services We Can Provide
Product Packaging
Wire is protected in coils, spools or straight-length bundles with moisture-resistant wrapping and labels for grade, diameter, heat and quantity. Typical export packaging for the same physical product form is shown below; final packing is confirmed for each order.

Application Scenarios

Chemical and marine fabrication
Material grade, dimensions, condition and inspection must be matched to the application requirements.

Wire forming and mesh
Material grade, dimensions, condition and inspection must be matched to the application requirements.

Fasteners and springs
Material grade, dimensions, condition and inspection must be matched to the application requirements.
FAQ
Is ASTM B863 Grade 2 wire the same as ERTi-2 welding wire?
No. ASTM B863 Grade 2 is titanium product wire identified as UNS R50400. ERTi-2 is a welding filler classification controlled by AWS A5.16 / ISO 24034. State the intended product and governing standard explicitly.
Can general Grade 2 wire be ordered for surgical implant use?
Not from the grade name alone. ASTM F67 establishes additional requirements for unalloyed titanium used for surgical implants. The application, governing specification, quality system, testing and traceability must be agreed before supply.
What information is needed to quote Grade 2 titanium wire?
Provide ASTM B863 revision, Grade 2 / UNS R50400, diameter and tolerance, condition, coil, spool or straight length, package weight, surface, quantity, application, MTC, heat/lot traceability and any dimensional, mechanical or cleanliness requirements.
