Among the many commonly used grades, although Grade 7 and Grade 11 both belong to the commercially pure titanium series and contain palladium (Pd) elements to enhance corrosion resistance, they have significant differences in strength, ductility, and usage scenarios.
If you are engaged in industries such as chemical equipment, power generation systems, seawater cooling systems, etc., understanding the differences between these two titanium alloys will help you make more appropriate material choices.

Both contain palladium, which is an important characteristic that distinguishes it from ordinary pure titanium and enables it to have better resistance to reducing acid corrosion.
Grade 7 has higher strength and is suitable for corrosion-resistant parts that need to bear pressure; Grade 11 has better ductility and is suitable for parts with higher requirements for formability.

Since both contain precious metal palladium (Pd), their prices are significantly higher than ordinary pure titanium such as Grade 1 and Grade 2. Generally:
- Grade 7 is slightly more expensive because of its higher strength and wider application;
- Grade 11 is more cost-effective and is particularly suitable for light load corrosion resistance occasions.
