ASTM B861/B338 Titanium Bar with Round Shape and Bright Surface Finish

Product Specification

Introduction

​Medical titanium bars are essential in various applications, particularly for surgical implants such as bone nails and dental components. These bars comply with industry standards like ASTM F67, ASTM F136, and ISO 5832-3, ensuring high quality and reliability. Available in material grades including Grade 2, Grade 5, and Grade 23 (Ti6Al4V ELI), they come in diameters ranging from 5mm to 20mm, with a standard length of 3000mm or customized as needed. The bars are produced in a round shape with a bright surface finish and meet tolerance grades of h7, h8, h9, and h10. Supplied in an annealed state, they are certified under ISO 9001, and third-party inspections (e.g., SGS, TUV) are available. Packaging is provided in export cartons or plywood cases, and quality assurance includes an EN10204.3.1 certificate, ensuring adherence to stringent quality standards.

Corrosion Resistance

Corrosion resistance is another standout feature of Grade 3 titanium. The alloy forms a protective oxide layer when exposed to air, which effectively prevents further oxidation. This characteristic is especially important in medical applications, where implants are frequently subjected to harsh environments within the body, including exposure to various bodily fluids. The corrosion resistance of Grade 3 titanium significantly contributes to the longevity of medical devices, ensuring that they remain functional over extended periods without degradation.

Applications in the Medical Industry

The versatility of Grade 3 titanium bars makes them suitable for a wide range of medical applications. Common uses include dental implants, orthopedic screws, plates, and other fixation devices. In orthopedic surgery, Grade 3 titanium is often used in load-bearing implants due to its high strength and low density. These attributes help reduce the overall weight of the implant while ensuring adequate structural support for healing bones.

In dentistry, Grade 3 titanium is favored for dental implants because of its excellent biocompatibility and ability to osseointegrate-where the bone grows around the implant-enhancing stability and longevity. The smooth surface finish of Grade 3 bars also aids in reducing bacterial adhesion, which is critical in minimizing infection risks during and after surgical procedures.

Manufacturing and Customization

The manufacturing processes for Grade 3 titanium bars commonly include forging, machining, and extrusion, which enable the creation of precise dimensions and custom shapes tailored to specific medical applications. With the capability to produce bars in various diameters, including 12mm, manufacturers can design components that meet the unique anatomical needs of patients.

Additionally, Grade 3 titanium bars can undergo a variety of surface treatments, such as anodizing and coating, to further enhance their properties. These treatments improve wear resistance and reduce friction, making the bars even more suitable for high-performance medical applications. By combining advanced manufacturing techniques with customizable options, Grade 3 titanium bars offer versatile solutions for the medical industry.
