Material Advantages

· 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

Product Application

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.

Manufacturing Capability

Baoji Huacan operates from China's "Titanium Valley" in Baoji, Shaanxi — the heart of Chinese titanium manufacturing. Our production infrastructure includes:

· VAR and PAM melting furnaces with annual capacity exceeding 5,000 tons

· 4,000-ton hydraulic press plus air hammers and rapid forging equipment

· 40+ CNC lathes and machining centers, including gantry systems

· Precision rolling mills for bar production with excellent surface finish

· Annual forging capacity exceeding 3,000 tons

This vertically integrated capability means you get consistent quality from raw ingot to finished rod — all under one roof.

Quality Control

Baoji Huacan follows a rigorous multi-stage inspection protocol:

Raw Material Verification — Spectrometer-based chemical composition analysis ensures only qualified titanium enters production.

In-Process Dimensional Checks — Technicians verify diameter and straightness at each production stage to maintain tight tolerances.

Ultrasonic Testing (NDT) — Internal voids, cracks, and inclusions are detected per AMS 2631 Class A1 standards without damaging the product.

Laser Micrometer Measurement — The 4.5mm diameter is verified against h7/h8 ISO tolerance. Length is confirmed within the specified tolerance range.

Chemical Analysis (ICP Testing) — Oxygen, nitrogen, and hydrogen levels are confirmed to meet ELI requirements where applicable.

Surface Integrity Check — Eddy current testing detects surface cracks or laps from the drawing process.

Final Documentation — Every batch ships with full traceability records, inspection reports, and EN 10204 3.1 MTC upon request.
