If you're searching for GR1 pure titanium wire, you probably need high corrosion resistance, excellent formability, and reliable biocompatibility—whether for medical implants, chemical processing, or aerospace applications.
This guide cuts through the technical jargon and gives you exactly what matters—from composition to real-world uses.
What is GR1 Titanium?
GR1 (Grade 1 titanium) is the purest and softest commercially available titanium, made of 99.5% unalloyed Ti.
✅ Why does that matter?
✔ Superior ductility – Easier to bend, weld, and shape than other grades
✔ Best corrosion resistance – Perfect for seawater, chemical tanks, and medical devices
✔ Biocompatible – Safe for implants (bone screws, dental posts)
✔ Lightweight yet strong – 45% lighter than steel, but just as tough
Fun Fact: GR1 is so soft that you can tie it in a knot—try that with GR5!
What is the Difference Between GR1 and GR2 Titanium?
| Feature | GR1 Titanium | GR2 Titanium |
|---|---|---|
| Purity | 99.5% Ti | 99.2% Ti |
| Strength | Lower (240 MPa yield) | Slightly stronger (345 MPa yield) |
| Ductility | More flexible (30% elongation) | Still formable (25% elongation) |
| Best For | Chemical tanks, implants | Heat exchangers, marine hardware |
Which one should you pick?
-
Need maximum corrosion resistance? → GR1
-
Need a bit more strength? → GR2
What Are the Different Grades of Titanium Wire?
Not all titanium wires are equal! Here’s a quick breakdown:
| Grade | Key Feature | Best Used For |
|---|---|---|
| GR1 | Softest, most corrosion-resistant | Medical implants, chemical tubing |
| GR2 | Balanced strength & formability | Marine hardware, heat exchangers |
| GR5 (Ti-6Al-4V) | Aerospace-grade strength | Aircraft parts, high-stress engineering |
| GR7 (Ti-0.2Pd) | Extreme acid resistance | Sulfuric acid plants, nuclear waste storage |
Pro Tip: If you're unsure, GR1 titanium wire is the safest bet for most non-load-bearing applications.
What Grade is Pure Titanium?
GR1 is the purest form of titanium wire, with no added alloys.
Other "pure" grades:
-
GR2 (slightly stronger, still 99%+ Ti)
-
GR3 & GR4 (rarely used in wire form)
Why does purity matter?
-
No alloying = better corrosion resistance (perfect for saltwater, acids)
-
Easier to weld & shape (no cracking risks)
Where to Buy GR1 Pure Titanium Wire?
Looking for high-quality, certified GR1 titanium wire? Here’s what to check:
✅ Certifications: ASTM B863, AMS 4951
✅ Diameter Range: 0.1mm – 6.0mm (custom cuts available)
✅ Surface Finish: Polished, pickled, or annealed
✅ Testing Reports: Mill certs (MTC), chemical analysis
