Description
The Gr.7 titanium hollow rod is a high-performance tubular product made from a titanium–palladium alloy (corresponding to Chinese grade TA9).
Manufactured through a precision drilling process, this material combines lightweight properties with excellent corrosion resistance, mechanical strength, and stability in harsh environments.
Its hollow design not only reduces weight but also improves heat
transfer efficiency and fluid handling performance, making it ideal
for use in chemical, marine, and energy applications.

Applications
1. Chemical Anti-Corrosion Equipment
Used in manufacturing acid transport pipelines, reactor linings, and heat exchanger tubes, where it resists strong acids (such as nitric acid and
hydrochloric acid) and organic solvents—significantly extending
equipment service life.
2. Marine and Energy Engineering
Ideal for seawater desalination systems, shipbuilding components, and offshore structures due to its excellent resistance to seawater corrosion, while
maintaining structural integrity and reducing overall weight.
3. High-End Industrial Applications
Applied in aerospace as lightweight structural parts and in the medical field for implantable supports, owing to its excellent biocompatibility and non-reactive nature.
Advantages
Outstanding resistance to oxidizing and reducing acids
Excellent corrosion resistance in chloride and acid environments
High strength-to-weight ratio and excellent ductility
Lightweight structure suitable for high-performance applications
Long service life with minimal maintenance requirements
Biocompatible and environmentally friendly
