- Product Description
6Al4V Titanium Bar – Aerospace-Grade Alloy for Demanding Industrial Applications
Baoji Jucheng Titanium Industry Co., Ltd., located in China's Titanium Valley, delivers precision-engineered 6al4v titanium bar products backed by over 20 years of manufacturing expertise.Our bars are made using vacuum melting, multi-stage forging, and controlled annealing.These processes help achieve tensile strengths between 895 and 1000 MPa, and yield strengths higher than 828 MPa.The bars come in diameters from 6mm to 450mm, and can be up to 12,000mm in length.We have about 3,000 tons of stock available, which allows us to quickly meet the needs of aerospace, medical, and marine industries.Our products follow ASTM B348, AMS 4928, and ASTM F136 standards, ensuring a consistent alpha-beta structure and tight control over impurities like oxygen and hydrogen—oxygen is limited to 0.20% or less, and hydrogen to 0.0125% or less.This helps provide better resistance to fatigue and corrosion.

Key Advantages You'll Appreciate
Heat Treatability for Enhanced Performance
Unlike commercially pure titanium, our alpha-beta alloy responds to solution treatment and aging. You can increase hardness by 15–20% post-delivery to match your exact load requirements.
Low Modulus for Medical Applications
At roughly half the stiffness of stainless steel, our bars minimize stress shielding in orthopedic implants. Your designs will better mimic natural bone mechanics, reducing patient complications.
Corrosion Immunity in Harsh Environments
The spontaneous TiO₂ passive film resists sour gas, seawater, and process chemicals. You'll see maintenance intervals stretch 3–5 times longer than conventional alloys in offshore rigs.
Superior Strength-to-Weight Ratio
With 60% of steel's density but comparable strength, you'll achieve weight savings critical for aerospace fuel efficiency and portable equipment designs.

How We Process Your Order
Our effective procedure guarantees that you receive materials that satisfy your exacting specifications:
1. Only premium ingots produced by vacuum-arc remelting are used, and their chemical compositions have been confirmed prior to forging.
2. To achieve ASTM 8–10 criteria for a fine grain structure, we employ a multi-step forging process that includes rotary forging at regulated temperatures.
3. To maintain diameter measurements within ±0.05mm, we employ precision machining processes such centerless grinding and CNC turning.
4. To lessen stress while maintaining the material's flexibility, we execute heat treatment by annealing at temperatures between 700 and 800°C.
5. Every shipment includes comprehensive testing, such as hardness tests, ultrasonic inspections, and dimensions reports.
Industries We Serve
Aerospace: Parts like bulkhead fittings, turbine mounts, and fastener inventory need to track back to AMS 4928 standards.
Medical Devices: Tools such as surgical instruments, bone screws, and prosthetic stems are made from ASTM F136 ELI bars.
Marine Engineering: Components like propeller shafts, pump parts, and subsea valve bodies are used in environments with over 30 years of seawater exposure.
Chemical Processing: Equipment including reactor parts and heat exchanger tubes are used in chlor-alkali and titanium dioxide plants.

Frequently Asked Questions
Q: What's the difference between Grade 5 and Grade 23?
Grade 23 (ELI) limits interstitial oxygen and iron for improved fracture toughness—essential for medical implants. Grade 5 suits structural aerospace parts where maximum strength matters more.
Q: Can you supply material certificates?
Yes. Every batch includes mill test reports with heat number traceability, chemical analysis, and mechanical test data per ASTM E8 and E384.
Q: What's your typical lead time for custom lengths?
Standard diameters ship within 7–10 days from our 3,000-ton inventory. Custom lengths up to 12 meters require 3–4 weeks for forging and inspection cycles.
Q: Do you offer small-quantity orders?
Absolutely. We accommodate R&D prototypes starting at 10 kg, with the same quality standards applied to multi-ton production runs.
Q: How do you ensure dimensional accuracy?
Centerless grinding achieves Ra 0.8μm surface finishes and ±0.05mm diameter tolerances. CNC turning provides even tighter control for precision applications.
