In the medical implant industry, medical titanium bar has become one of the most important raw materials for orthopedic implants, dental implants, and surgical devices. Thanks to its excellent biocompatibility, corrosion resistance, and mechanical performance, implant grade titanium bar is widely used in spinal systems, trauma fixation devices, dental implants, joint prostheses, and precision surgical components.

For medical OEM manufacturers, selecting qualified medical grade titanium rod is not only related to product quality, but also directly affects regulatory compliance, long-term reliability, and supply chain stability.

Why Titanium Bars Are Widely Used in Medical Implants

Compared with stainless steel materials, titanium bar for medical implants offers lower elastic modulus, superior corrosion resistance, and better biological compatibility.

Key advantages include:

• Excellent biocompatibility;
• Stable passive oxide layer;
• Good MRI compatibility;
• Reduced stress shielding effect;
• High strength-to-weight ratio.

Today, ASTM F67 titanium bar is commonly used for commercially pure titanium implants, while ASTM F136 titanium bar is preferred for high-strength orthopedic and dental applications.

Common Grades of Medical Titanium Bars

ASTM F67 Commercially Pure Titanium

ASTM F67 titanium rod includes:

• Grade 1
• Grade 2
• Grade 3
• Grade 4

Among them, Grade 4 titanium bar is widely used in dental implant manufacturing because of its balanced strength and biocompatibility.

ASTM F136 Titanium Alloy Bar

ASTM F136 titanium bar refers to Ti-6Al-4V ELI alloy, featuring:

• Higher tensile strength;
• Excellent fatigue resistance;
• Superior load-bearing capability.

It is widely used in:

• Spinal implants;
• Trauma fixation systems;
• Orthopedic screws;
• Joint prostheses.

Manufacturing Process of Medical Titanium Bars

Vacuum Melting Technology

High-quality implant titanium rod is typically produced using:

• VAR melting;
• Multiple vacuum melting processes.

This helps reduce inclusions and improve structural uniformity.

Heat Treatment & Microstructure Control

Heat treatment significantly affects:

• Grain size;
• Strength;
• Ductility;
• Fatigue performance.

For long-term implant applications, stable microstructure control is essential.

Surface Quality Control

Medical-grade titanium round bar usually requires:

• Crack-free surface;
• No folding defects;
• Low surface roughness;
• No heavy oxidation.

Surface defects may become fatigue crack initiation points during service.
