4.5mm Titanium Rod for Medical, Aerospace & Industrial Applications — High Strength, Lightweight, Custom Supply

This 4.5mm titanium rod is a high precision small diameter cylindrical bar product made mostly from Grade 5 (Ti-6Al-4V) or Grade 23 (Ti-6Al-4V ELI) titanium alloy. It delivers tensile strength exceeding 895 MPa while maintaining a modulus of elasticity of approximately 110 GPa — ideal for load-bearing use in constrained spaces. At Baoji Huacan New Metal Materials Co., Ltd., we produce this rod to meet ASTM B348 and AMS standards, with full OEM/ODM customization available.

· High strength-to-weight ratio — offers ~45% weight reduction versus steel equivalents without sacrificing tensile integrity

· Superior corrosion resistance — the stable TiO₂ oxide layer prevents galvanic corrosion in mixed-material assemblies

· Excellent biocompatibility — no ion release or metallosis, suitable for implant-grade medical applications

· Intraoperative contourability — enough ductility for surgeons to shape during spinal procedures without brittleness

· Wide temperature performance — operates reliably from -54°C to 350°C for aerospace use

Titanium precision parts processing

Medical — Cervical Spine Fixation

The 4.5mm profile is the industry standard for posterior cervical stabilization systems. It connects pedicle screws across vertebrae while remaining malleable enough for intraoperative contouring — critical in both adult cervical and pediatric spinal correction cases.

Aerospace — Fasteners & Locking Pins

Machined into lightweight blind bolts, lockbolts, and locking pins for airframe assembly and satellite deployment mechanisms. Its corrosion resistance against carbon fiber composites makes it ideal for mixed-material assemblies.

Industrial & Marine — Valves, Sensors & Subsea Components

4.5mm titanium rod Used for valve stems and sensor probes in offshore oil and gas instrumentation. Immunity to crevice corrosion and saltwater pitting ensures long service life in subsea environments with no maintenance access.

BJHC follows a structured multi-stage inspection protocol:

Raw Material Verification — spectrometer-based chemical composition analysis and supplier certification checks before production begins.

In-Process Control — real-time dimensional checks at every manufacturing stage to keep tolerances tight throughout.

Non-Destructive Testing — ultrasonic testing detects internal cracks, voids, or inclusions without damaging the product.

Final Dimensional & Mechanical Inspection — CMM, micrometers, and hardness testers verify tensile strength, yield strength, and dimensional accuracy against ASTM, AMS, and DIN standards.

Documentation — each batch ships with full inspection reports, material traceability records, and available certificates (MTC, COC, EN10204 3.1).

Frequently asked Questions

Learn more about titanium grades, custom machining, lead times, and OEM solutions.

Q: What grades are available for your titanium rods?

A: We provide Grade 2, Grade 4, Grade 5 (Ti-6Al-4V), Grade 7, Grade 9 and Grade 23 (Ti-6Al-4V ELI). The choice of grade depends on your application. For medical implants, you normally need either Grade 5 or Grade 23.

Q: Do you do custom lengths and diameters?

A：Yeah. All sizes are customisable according to your designs or requirements. This is our regular product, however we can also accept alternative diameters and lengths.

Q: What is the rating of your rods?

A : Our rods are as per ASTM B348, AMS 4928 & other International standards like DIN, ISO etc. per customer’s requirement.

Q: How long does production take?

A：Lead time depends on order volume and specifications. Prototype and small-batch orders are typically faster. Contact us directly for an accurate timeline.
