Titanium Dowel Pins Medical Grade Dowel Pins TA1 TA2 TC4

Descrição

What Are Titanium Dowel Pins?

Titanium dowel pins are precision cylindrical fasteners used to align and secure components in machinery, aerospace assemblies, medical devices, and high-performance engineering applications. Made from titanium alloys, they offer exceptional strength-to-weight ratio, corrosion resistance, and biocompatibility, making them ideal for demanding environments.

Key Features of Titanium Dowel Pins

1. Materials

• Commercially Pure Titanium (Grade 2, Grade 4) – Good corrosion resistance, moderate strength.

• Titanium Alloys (Grade 5 – Ti-6Al-4V) – High strength, heat resistance, aerospace-grade.

• Beta Titanium Alloys (e.g., Ti-3Al-8V-6Cr-4Mo-4Zr) – Enhanced fatigue resistance for extreme conditions.

2. Surface Treatments

• Anodizing (Type II or III) – Improves wear resistance & provides color coding.

• Passivation – Enhances corrosion resistance by removing free iron particles.

• Polishing/Mirror Finish – Reduces friction in medical or precision applications.

• Teflon (PTFE) Coating – Low-friction, chemical-resistant for specialized uses.

3. Common Specifications

• Diameter: 1mm to 50mm (standard range).

• Length: 5mm to 300mm (custom lengths available).

• Tolerances:

  • Standard (m6/h6) – For general alignment.

  • Precision (h5/g6) – For tight-tolerance applications.

• Head Styles: Plain, flanged, grooved, or threaded ends.

4. Applications

• Aerospace: Wing assemblies, engine mounts, landing gear alignment.

• Medical: Surgical instruments, orthopedic implants, dental devices.

• Automotive Racing: Lightweight engine/transmission alignment.

• Industrial Machinery: Precision tooling, robotic arms, CNC fixtures.

• Marine & Chemical: Corrosion-resistant equipment in saltwater/acidic environments.

Excellent Case: Titanium Dowel Pins in Aircraft Wing Assembly

Application: In Boeing 787 Dreamliner wing construction, Grade 5 Ti-6Al-4V dowel pins are used to align composite wing panels with the fuselage.

Why It’s Effective:

• Lightweight Strength: Titanium reduces weight vs. steel while handling structural loads.

• Corrosion Resistance: Withstands humidity, fuel, and temperature extremes.

• Precision Fit: Tight tolerances (h5) ensure perfect alignment for aerodynamic efficiency.

• Fatigue Resistance: Titanium’s durability prevents failure under cyclic stress.

Result: Enhanced aircraft performance, fuel efficiency, and long-term reliability.

Titanium dowel pins are critical in high-stress, lightweight, and corrosive environments, offering unmatched performance in aerospace, medical, and advanced engineering applications.
