Titanium Grade 7 Filler Wire, commonly designated as ERTi-7 or UNS R52400, is a commercially pure titanium alloy that contains a small addition of palladium. This addition significantly enhances corrosion resistance, especially in reducing acid environments.
Titanium Grade 7 is very similar to Titanium Grade 2, but the addition of palladium improves resistance to chemical corrosion and aggressive environments. The alloy provides excellent resistance to acids, chlorides, and seawater, making it ideal for highly corrosive industrial applications.
Titanium Grade 7 filler wire is commonly used for welding titanium components and titanium alloys in industries that require exceptional corrosion resistance. It is widely used in industries such as chemical processing, marine engineering, pharmaceutical manufacturing, pollution control, and desalination plants.
Due to its superior corrosion resistance and excellent weldability, Titanium Grade 7 filler wire is widely preferred for welding equipment used in aggressive chemical environments.
Key Features of Titanium Grade 7 Filler Wire
