Why TA1 (Grade 1) Titanium Is Food-Safe
- Inert and Non-Toxic: Titanium, especially high-purity grades like TA1/Grade 1, is chemically inert. It does not react with food—even acidic substances like tomato sauce—and does not leach harmful substances.
- Excellent Corrosion Resistance & Biocompatibility: TA1 titanium forms a stable oxide layer (TiO₂) on its surface that prevents corrosion and makes it safe for contact with food. It’s also widely used in medical implants, underscoring its safety profile
- FDA Recognition: Titanium is acknowledged by the U.S. Food and Drug Administration (FDA) as a safe, non-toxic material for food contact applications
- User Confidence & Hypo-allergenicity: Enthusiasts favor Grade 1 titanium for containers and utensils due to its inertness and lack of reactive trace metals—making it a safer choice for those sensitive to metals like nickel
A Note on Titanium Dioxide (TiO₂)
Titanium dioxide, used as a food additive, is different from titanium metal. While the metal itself is safe, TiO₂—especially in nanoparticle form—has raised health concerns and restrictions, particularly in the EU. Rest assured, these issues do not apply to solid, high-purity titanium metal such as TA1.
