Wuxi Weiman Gaodeng Special Steel Co., Ltd., a specialized manufacturer established in 2017 and operating from a modern 1,000-3,000 sqm facility in Wuxi, China, proudly presents our premium Medical Grade Titanium Alloy Bar GR7. With a dedicated workforce of 101-200 professionals and an annual export value of US$5-10 Million, we serve demanding markets globally, including North America, Europe, Asia, and Oceania. Our GR7 Titanium Bars are engineered with the highest purity and stringent biocompatibility certifications, making them the trusted core material for critical life-sustaining medical devices and implants where exceptional corrosion resistance, unparalleled strength-to-weight ratio, and absolute tissue compatibility are non-negotiable.
Core Product Features & Specifications:
- Superior Biocompatibility: Certified to meet rigorous medical standards (referencing ISO 5832-2 / ASTM F67), ensuring safe, long-term contact with human tissues and bodily fluids without adverse reactions. Ideal for permanent and temporary implants.
- Exceptional Corrosion Resistance: GR7 alloy (Ti-0.2Pd) offers outstanding resistance to pitting and crevice corrosion in chloride environments (e.g., physiological saline), far exceeding pure titanium and other grades, crucial for implant longevity.
- Optimized Mechanical Properties: Provides an excellent balance of high strength, low density, and ductility, essential for machining intricate surgical tool components and load-bearing implants without compromising structural integrity.
- Non-Magnetic & Low Modulus: Perfect for MRI compatibility and reducing stress shielding effects in bone implants, promoting better osseointegration and patient comfort.
- Controlled Microstructure & Purity: Produced under strict vacuum melting processes (VAR) ensuring low interstitial element content (O, N, C, Fe, H) and homogeneity, critical for fatigue performance and weldability.
- Versatile Processing: Supplied in various surface finishes (Polished, Peeled, Turned) and ready for further precision machining, forging, or additive manufacturing into final medical components.
Technical Specifications (Typical):
| Property | Standard Value | Test Method |
|---|---|---|
| Tensile Strength (min) | 345 MPa | ASTM E8 |
| Yield Strength (0.2% Offset, min) | 275 MPa | ASTM E8 |
| Elongation (min) | 20% | ASTM E8 |
| Reduction of Area (min) | 30% | ASTM E8 |
| Density | ~4.51 g/cm³ | - |
| Primary Composition (Ti base) | 0.12-0.25% Pd | ASTM E1409 |
Benefits for Medical Device Manufacturers:
- Enhanced Implant Longevity: Minimizes risk of in-vivo corrosion failure, extending implant service life.
- Reduced Rejection Risk: Proven biocompatibility lowers the risk of adverse tissue reactions and implant rejection.
- Design Freedom: Excellent machinability and formability allow for complex geometries in surgical tools and implants.
- Regulatory Compliance: Material traceability and certification support streamline your regulatory submissions (FDA, CE).
- Supply Chain Reliability: Partner with a proven manufacturer experienced in serving global medical OEMs with consistent quality.

Frequently Asked Questions (FAQ):
-
Q: What specific biocompatibility certifications do your GR7 bars hold?
A: Our bars are produced to meet the requirements of ISO 5832-2 and ASTM F67 standards for implantable materials. We provide material certificates confirming compliance, including chemical composition and mechanical properties. Specific biocompatibility test reports (like cytotoxicity, sensitization, irritation) for the final device are typically the responsibility of the device manufacturer. -
Q: Can you supply bars outside the typical diameter and length ranges mentioned?
A: Yes, as a manufacturer, we specialize in customization. We can produce GR7 titanium bars in diameters and lengths tailored to your specific machining or implant manufacturing needs. Please inquire with your requirements. -
Q: What surface finishes are standard, and can you provide specific roughness values (Ra)?
A: Standard finishes include Polished (smooth), Peeled (cold-drawn finish), and Turned (machined). We can achieve specific surface roughness (Ra) values upon request to suit your machining or final implant surface requirements. -
Q: Do you provide full material traceability?
A> Yes. Each batch of our Medical Grade GR7 Titanium Bar comes with a Material Test Certificate (MTC) or Mill Test Certificate detailing the heat number, chemical analysis, mechanical test results, and compliance with relevant standards, ensuring full traceability. -
Q: How does GR7 compare to pure Titanium (Grade 2) for medical use?
A: GR7 (Ti-0.2Pd) offers significantly superior resistance to crevice corrosion in chloride-containing environments (like body fluids) compared to Grade 2. While Grade 2 is often used, GR7 is preferred for more demanding applications or where enhanced long-term corrosion resistance is critical. -
Q: What are the typical lead times for custom orders?
A: Lead times depend on the specifics of the order (size, quantity, finish). Standard sizes and finishes may have shorter lead times, while fully customized orders require more production time. We prioritize providing accurate lead time estimates upon order confirmation. -
Q: Can you supply bars suitable for additive manufacturing (AM) processes?
A> While we primarily supply solid bar stock, we can discuss the suitability of our material and potential processing routes for AM feedstock. Surface condition and microstructure are key factors. -
Q: What packaging do you use to ensure product integrity during transit?
A: Medical Grade bars are carefully handled and packaged to prevent surface damage and contamination. Common methods include protective caps on ends, plastic wrapping, wooden crating, and desiccants as needed, ensuring safe arrival at your facility.
