We specialize in supplying high-performance titanium wires with excellent corrosion resistance, biocompatibility, and strength, suitable for demanding industrial, marine, chemical, and biomedical applications.
Our Titanium Grade 7 wires are available in a wide range of diameters, finishes, and specifications to meet the requirements of chemical processing, aerospace, marine, desalination, and healthcare industries. We deliver across India and export globally to the USA, Europe, the Middle East, Africa, and Southeast Asia, ensuring strict compliance with international standards and timely delivery.
Titanium Grade 7 wires are titanium alloy wires with added palladium (0.12–0.25%), which significantly enhances their corrosion resistance in reducing and oxidizing environments, particularly against chloride stress corrosion cracking and oxidizing acids.
This grade combines the properties of commercially pure titanium (similar to Grade 2) with palladium for superior chemical resistance, making it ideal for chemical, marine, pharmaceutical, and desalination applications. Titanium Grade 7 wires are soft, ductile, and highly formable, allowing easy bending, drawing, and fabrication while maintaining high corrosion resistance and biocompatibility.
Key Features of Titanium Grade 7 Wires
These features make Titanium Grade 7 wires a preferred choice for industrial, chemical, marine, and biomedical applications where corrosion resistance and reliability are critical.
| Element | Composition (%) |
|---|---|
| Titanium (Ti) | Balance (~99%) |
| Palladium (Pd) | 0.12 – 0.25 |
| Iron (Fe) | 0.20 max |
| Oxygen (O) | 0.25 max |

Role of Key Elements
The addition of palladium makes Grade 7 superior to Grade 2 in aggressive chemical conditions, particularly nitric acid and seawater applications.
Titanium Grade 7 wires retain excellent ductility, toughness, and strength over a wide temperature range, allowing them to withstand mechanical stress in industrial and chemical applications.
These physical properties ensure dimensional stability and performance under thermal cycling and variable environmental conditions.
Titanium Grade 7 wires are highly resistant to:
This makes Titanium Grade 7 wires ideal for chemical plants, desalination units, marine equipment, and pharmaceutical applications.
Titanium Grade 7 is commercially pure and does not require hardening, although cold working or annealing can adjust mechanical properties.
Cold Working & Annealing:
Cold working allows Titanium Grade 7 wires to achieve specific mechanical performance while maintaining excellent corrosion resistance.
