Titanium Alloy Wire and Bar Overview
Titanium Alloy Wire and Bar are lightweight, high-strength metallic materials widely used in aerospace, medical devices, chemical processing, marine engineering, welding, electronics and precision machining industries.
Compared with stainless steel and conventional alloy steel, titanium offers a much lower density, excellent corrosion resistance and strong performance in seawater, chloride media and oxidizing environments. Titanium naturally forms a stable oxide film, which gives it outstanding resistance to corrosion in many aggressive service conditions.
Xi'an Dongmeng Group Co., Ltd supplies ASTM B348 titanium bar and ASTM B863 titanium wire in commercially pure titanium and titanium alloy grades, including Grade 2, Grade 5 Ti-6Al-4V, Grade 7, Grade 9, Grade 12 and Grade 23 ELI. Products can be supplied in straight length, coil, spool, polished bar, ground bar and customized cut-to-size formats.

Processing Performance Analysis
Titanium alloy wire and bar offer excellent performance during precision machining, cold drawing, forging, straightening and polishing. Grade 2 titanium is easier to form and weld, while Grade 5 Ti-6Al-4V provides higher strength for aerospace and structural applications.
For tight-tolerance bar products, centerless grinding and polishing can improve dimensional accuracy and surface finish. For titanium wire, cold drawing and annealing help achieve stable diameter control, surface cleanliness and consistent mechanical behavior.
Welding Performance Analysis
Commercially pure titanium grades such as Gr1 and Gr2 have excellent weldability. Titanium alloy grades such as Gr5, Gr7, Gr9 and Gr12 can also be welded, but shielding gas protection is critical because titanium reacts easily with oxygen, nitrogen and hydrogen at elevated temperatures.
Recommended welding considerations:
| Welding Factor | Recommendation |
|---|---|
| Shielding Gas | High-purity argon |
| Surface Cleaning | Remove oil, oxide and contamination before welding |
| Heat Control | Avoid excessive heat input |
| Welding Wire | Match grade according to base metal |
| Post-weld Inspection | Visual inspection, PT, dimensional inspection if required |
Corrosion Resistance Analysis
Titanium is widely selected for harsh environments because of its passive oxide film. It performs well in seawater, wet chlorine, many chloride solutions and oxidizing acids. Grade 7 and Grade 12 provide enhanced corrosion resistance for more demanding chemical and marine conditions.
| Environment | Recommended Grade |
|---|---|
| Seawater | Gr2, Gr7, Gr12 |
| Chemical Processing | Gr2, Gr7, Gr12 |
| Aerospace Components | Gr5, Gr9 |
| Medical Components | Gr4, Gr5, Gr23 |
| Welding Applications | ERTi-1, ERTi-2, ERTi-5, ERTi-7 |
| Precision Machining | Gr2, Gr5 |
Manufacturing Capability
| Capability | Details |

| Cutting | Custom cut length available |
| Tolerance Control | Tight tolerance available upon request |
| Documentation | MTC, chemical composition report, mechanical test report |
| Third-party Inspection | SGS, BV, TÜV or customer-appointed inspection |
Excellent corrosion resistance:
Titanium alloys are highly resistant to corrosion, even in harsh environments such as seawater and chloride solutions. This makes them suitable for marine applications, chemical processing equipment, and oil and gas production.
Biocompatibility:
Certain titanium alloys are biocompatible, meaning they are well-tolerated by the human body and can be used in medical implants such as artificial joints, bone screws, and dental implants.
High heat resistance:
Titanium alloys maintain their strength at elevated temperatures, making them valuable for applications in high-temperature environments such as jet engines and power plants.
High strength-to-weight ratio:
Titanium alloys are significantly lighter than steel but can offer comparable or even superior strength. This makes them ideal for applications where weight reduction is a critical factor, such as in aerospace, automotive, and medical industries.
