Ti-0.15Pd Alloy Advantages, Applications & Available Formats
Grade 7 titanium alloy offers mechanical and physical properties comparable to Grade 2, but with the addition of the interstitial element palladium. This gives Grade 7 the highest corrosion resistance of all titanium alloys in reducing acids.
GNEE is an ISO 9001-certified industrial metals supplier serving industrial manufacturers requiring high-performance metals and alloys. We can supply single pieces or entire batches of Grade 7 titanium alloys, and our extensive product selection enables us to fulfill repeat orders. We have experience supplying over 45 countries worldwide with fast turnaround and high-quality metals. We comply with most ASME, ASTM, AMS, and military specifications, as well as most international standards, including full DIN EN10204 3.1 certification.
Titanium Grade 7 Applications
Titanium Grade 7 also has excellent weldability and fabricability while being the most resistant to corrosion in reducing acids. This makes Ti Grade 7 ideal for handling corrosive chemicals and fluids. Some industries that use Titanium Grade 7 include:
Chemical Processes
Production Equipment Components
Ducting
Heat exchangers
Pulp & Paper
Desalination
Air Pollution Control Equipment

Titanium Grade 7 Specifications
Titanium Grade 7 contains the added interstitial element palladium, which makes it an alloy. Titanium Alloy Grade 7 with 0.1% palladium is similar to Grade 2, but with improved resistance to general and localized crevice corrosion in a broad range of reducing acid environments, including chlorides, and where low pH and high temperatures above 180ºF (83ºC) to 500ºF (260ºC) are prevalent.
