3mm Titanium Rod – Grade 5 Precision Bar for Industrial & Medical Applications

Baoji Huacan's 3mm titanium rod is a high-precision, small-diameter cylindrical bar manufactured from Grade 5 (Ti-6Al-4V) or other titanium alloys through cold drawing and centerless grinding. Designed for high stress, weight sensitive situations, it provides excellent corrosion resistance, biocompatibility and dimensional stability. The diameter accuracy is maintained to ISO h6/h7 and straightness to 0.5mm/m. This rod is an important feedstock for Swiss-style CNC lathe machining, dental components and aerospace fasteners.

· Tight Tolerance: ISO h6/h7 diameter control ensures precise fit in micro-mechanical assemblies

· Superior Straightness: ≤ 0.5mm/m prevents vibration and chatter in CNC bar feeders

· Multi-Grade Availability: Grade 2 for weldability, Grade 5 for strength, Grade 23 for medical implants

· Corrosion Resistance: Performs reliably in body fluids, seawater, and chemical environments

· Lightweight: Approximately 56% lighter than stainless steel at comparable strength

· Temperature Stability: Maintains dimensional accuracy from -55°C to 150°C

Our Precision Parts Processing Workshop

Titanium precision parts processing

Medical & Dental: Used as feedstock for Kirschner wires, external fixation pins, and dental abutment screws. Grade 23 ELI is required for permanent implants due to its superior fracture toughness and lower oxygen content per ASTM F136.

Aerospace Fastening: Deployed in non-structural rivets, locking pins, and sensor probes where localized weight reduction is critical and parts must endure rapid thermal cycling (-55°C to 150°C).

Precision Welding & Industrial : Used as a straight length TIG welding filler wire in automated welding systems. Grade 2 is very weldable; Grade 5 needs argon shielding to avoid embrittlement.

OUTDOOR & RC MODELS 3mm titanium rod Grade 5 titanium rod worked into ultralight tent stakes and RC model shafts where the need for narrow diameter and good bending resistance.

Frequently asked Questions

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

Q: What tolerance is standard for the product used in Swiss machining?

A：ISO h6 or h7 with centerless ground finish and chamfered ends are required for reliable bar-feeder performance.

Q: What is the difference between Grade 5 and Grade 23?

A：Both are Ti-6Al-4V. Grade 23 has lower oxygen and iron content, making it mandatory for permanent medical implants where fracture toughness is critical.

Q: How is straightness maintained during shipping?

A：Rods are packed in rigid PVC tubes. Lengths of 1000mm or 2000mm are recommended to keep straightness within 1mm/m during transit.

Q: Is cold bending possible?

A：Grade 1 and 2 rods can be cold bent. Grade 5 has high spring-back and typically requires heat bending.

Rods are packed in rigid PVC tubes to maintain straightness during transit, then placed in vacuum-sealed bags with desiccants and wooden crates for bulk orders. Air freight and sea freight options are available. Full labeling and traceability documentation included.

You can specify diameter tolerance (h6, h7, or h8), length, material grade, surface treatment, and end condition. Custom logos via laser marking or CNC engraving are available. OEM/ODM production based on customer drawings is fully supported — from prototypes to mass production.
