Titanium Grade 4 Capillary tubes are precision-engineered small-diameter tubes made from the strongest of the commercially pure titanium grades. Known for their exceptional strength and excellent corrosion resistance, these capillary tubes are designed for use in demanding environments where mechanical performance, precision, and resistance to aggressive media are critical.
Titanium Grade 4 (UNS R50700) is a commercially pure titanium alloy that contains higher oxygen content than Grades 1–3. This increased oxygen content results in significantly higher tensile and yield strength while still maintaining good ductility and weldability. The material offers a strong balance between performance and corrosion resistance.
Capillary tubes are characterized by their small outer diameters, often as low as 0.2 mm, and extremely thin walls. Titanium Grade 4 Capillary tubes are manufactured with tight dimensional tolerances and smooth internal surfaces, making them ideal for fluid flow, gas delivery, and micro-scale instrumentation applications. Standard lengths range from a few centimeters to several meters, depending on the application.
Titanium Grade 4 provides outstanding corrosion resistance in a wide range of environments, including seawater, oxidizing acids, and chloride-rich atmospheres. Its natural oxide layer forms immediately upon exposure to air or moisture and acts as a protective barrier, making these tubes suitable for long-term use in marine, offshore, and chemical environments.
Specification of Titanium Grade 4 Capillary tubes
| Specification | Details |
|---|---|
| Chemical Composition | C ≤ 0.08%, O ≤ 0.25%, N ≤ 0.03%, H ≤ 0.015%, Fe ≤ 0.30%, Ti remainder |
| Outer Diameter (OD) | Typically ranges from ~0.2 mm to ~8 mm (varies by source) |
| Wall Thickness (WT) | Commonly between 0.015 mm to 0.5 mm |
| Tolerance (OD / WT) | OD ± 0.003 mm; Wall ± 0.005 mm; Length accuracy down to ± 0.03 mm in some cases |
| Length | Customizable; some vendors list up to several meters, e.g. ≤ 6000 mm |
Among commercially pure titanium grades, Grade 4 exhibits the highest strength. With a typical tensile strength of over 550 MPa (80 ksi) and good fatigue resistance, Titanium Grade 4 Capillary tubes can handle high-pressure systems while maintaining structural integrity. This makes them especially valuable in aerospace, medical, and industrial applications.
Chemical Composition of Titanium Grade 4 Capillary tubes
| Element | Maximum Content (%) | Notes |
|---|---|---|
| Titanium (Ti) | Balance (≥ 99.2%) | Main element; balance of the composition |
| Oxygen (O) | 0.22 – 0.40 | Higher oxygen increases strength |
| Carbon (C) | ≤ 0.08 | Impacts mechanical properties & weldability |
| Nitrogen (N) | ≤ 0.05 | Strengthens but reduces ductility |
| Hydrogen (H) | ≤ 0.015 | Affects brittleness; must be tightly controlled |
| Iron (Fe) | ≤ 0.50 | Minor alloying element |
| Other Elements (each) | ≤ 0.10 | Any individual unlisted impurity |
| Other Elements (total) | ≤ 0.40 | Sum of all unlisted trace elements |

❓ Frequently Asked Questions (FAQs)
Q1:What is Titanium Grade 4?
Titanium Grade 4 is the strongest of the commercially pure (CP) titanium grades. It offers excellent corrosion resistance, good formability, and higher strength compared to Grades 1–3. It is non-magnetic and biocompatible.
Q2: What are capillary tubes?
Capillary tubes are thin-walled, small-diameter tubes typically used to transport fluids or gases with precision. They are often used in medical, analytical, and industrial applications where tight tolerances are essential.
Q3: Are these tubes weldable?
Yes, Titanium Grade 4 is weldable using techniques like GTAW (TIG) or plasma arc welding, though precautions must be taken to avoid contamination (e.g., shielding with argon).
