The Gr5 Titanium Bar (Ti-6Al-4V) is the workhorse of the titanium industry, offering an exceptional strength-to-weight ratio that is 40% lighter than steel but with comparable tensile strength (≥895 MPa). To meet diverse industry requirements, we maintain dual-inventory options:
Unlike standard rolled bars found in the market, our titanium bars are manufactured using a Forging Process. This technique effectively breaks down coarse grain structures, resulting in a refined Alpha-Beta microstructure that significantly enhances fatigue life and impact resistance.
Crucially, all our bars undergo a Vacuum Annealing process. This heat treatment relieves internal stress generated during forming, ensuring the material remains straight and stable during high-speed CNC machining without warping or deformation.
We strictly control interstitial elements to ensure material safety and performance.

Rigorous Non-Destructive Testing (NDT) To guarantee structural integrity, 100% of our aerospace and medical-grade titanium bars undergo Ultrasonic Testing (UT) in accordance with AMS-STD-2154 Class A. This ensures the material is free from internal cracks, porosity, inclusions, and other metallurgical defects that could compromise safety.
Comprehensive Lab Testing Our in-house laboratory, capable of Third-Party Verification (SGS/TUV), performs the following tests for every heat number:
Certificates & Reports We provide a complete documentation package for validation:
Due to its high specific strength and heat resistance up to 400°C, our Gr5 titanium bars are widely used in critical components:
Our Gr23 (Ti-6Al-4V ELI) bars feature extra low interstitial elements, providing superior biocompatibility and fracture toughness. Ideal for:
With excellent corrosion resistance (PREN ≥ 30) in seawater and chemical environments, Gr5 bars are the material of choice for:
Machining Recommendations Titanium Gr5 has low thermal conductivity, which can cause heat buildup at the cutting edge.
Welding Notes Ti-6Al-4V is weldable but requires careful preparation.
Export-Grade Protection We understand the importance of surface quality. Our packaging ensures bars arrive in pristine condition:
Supply Capacity
Q: What is the difference between Gr5 and Gr23 (ELI) titanium bars?
A: Gr5 (Ti-6Al-4V) is the standard grade for industrial and aerospace use with high strength. Gr23 (Ti-6Al-4V ELI) has reduced Oxygen and Iron content, offering better ductility and fracture toughness, making it essential for medical implants (ASTM F136).
Q: Can you provide bars with h7 tolerance?
A: Yes, we offer precision Centerless Grinding services to achieve ISO 286 h7, h8, or h9 tolerances, which is ideal for CNC Swiss-style machining.
Q: Does your material meet AMS 4928 aerospace standards?
A: Yes. We can supply materials that are dual-certified to ASTM B348 and AMS 4928. Please specify “Aerospace Grade” in your inquiry so we provide the correct NDT reports and certification.
Q: Do you support third-party inspection?
A: Absolutely. We welcome inspections by SGS, TUV, BV, or your assigned inspector at our Shaanxi facility before shipment.
