Titanium Grade
The difference between titanium grade 2 and 5
Pure titanium with high corrosion resistance
Titanium grade 2 is so-called "commercially pure titanium" (CP titanium) with a purity of around 99%. It is characterized by its excellent corrosion resistance, hypoallergenicity and relative ease of processing compared to grade 5. However, due to its softness compared to other titanium alloys, it is more susceptible to scratches and dents.
High-strength titanium alloy for demanding applications
Grade 5 titanium (also known as Ti-6Al-4V) is an alloy consisting of around 90% titanium, 6% aluminum and 4% vanadium. This combination makes the material significantly stronger and more resistant to scratches than grade 2 titanium. Due to these properties, it is often used in the aerospace and motorsport industries.
Conclusion
Titanium is an exceptional material for wristwatches, which has its advantages in both grade 2 and grade 5. While grade 2 scores points above all for its purity and corrosion resistance, grade 5 offers greater strength and resistance. Depending on the intended use and personal preference, it is worth paying attention to the alloy used when buying a titanium watch.The disadvantages of grade 2 can be offset cost-effectively by surface hardening.
