Comparing Popular Special Titanium Alloys for Industrial Use

Titanium’s unique properties make it valuable across many industries — but not all titanium is created equal. Special titanium alloys are engineered to perform under specific conditions, whether that’s high stress, corrosion, or temperature extremes.

This article compares several commonly used special titanium alloys to help you identify the best option for your industrial application.

Ti-6Al-4V vs Ti-6Al-2Sn-4Zr-2Mo (Ti 6242)

Both alloys are known for their strength and aerospace-grade reliability, but they serve different purposes.

Property	Ti-6Al-4V	Ti-6242
Strength	High	Very High (especially at elevated temps)
Temperature Performance	Up to 400°C	Up to 550°C
Machinability	Good	Moderate
Typical Application	Fasteners, implants	Jet engine parts, hot zones

Conclusion: Ti-6Al-4V is more versatile and easier to work with, while Ti-6242 excels in high-temperature conditions.

Ti-15V-3Cr-3Sn-3Al vs Ti-3Al-8V-6Cr-4Mo-4Zr (Beta C)

These two beta alloys are used where formability or extreme strength is needed.

Property	Ti-15V-3Cr-3Sn-3Al	Beta C
Cold Formability	Excellent	Low
Strength After Aging	Moderate-High	Very High
Weldability	Good	Difficult
Use Case	Cold-formed parts	Hydraulic systems, fasteners

Conclusion: Ti-15-3 is great for shaped or bent parts; Beta C is chosen when extreme strength and pressure resistance are required.

Corrosion-Resistant Grades: Ti-0.2Pd (Grade 7) vs Ti-0.3Mo-0.8Ni (Grade 12)

When operating in aggressive chemical or marine environments, corrosion resistance is key.

Property	Grade 7 (Ti-0.2Pd)	Grade 12 (Ti-Mo-Ni)
Chloride Resistance	Excellent	Very Good
Acid Resistance	Strong	Enhanced
Weldability	Excellent	Excellent
Typical Use	Heat exchangers, tanks	Desalination, chemical piping

Conclusion: Both are top choices for corrosion-prone systems, with Grade 12 offering more mechanical strength for structural components.
