This detailed article compares Grade 2 and Grade 5 titanium bars, highlighting their chemical compositions, mechanical properties, corrosion resistance, fabrication characteristics, and typical applications. Grade 2 titanium is commercially pure, offering excellent corrosion resistance and ductility, ideal for marine, chemical, and medical uses. Grade 5 titanium, alloyed with aluminum and vanadium, provides superior strength and temperature resistance, making it suitable for aerospace, automotive, and high-performance applications. The choice between them depends on balancing strength, corrosion environment, fabrication ease, temperature exposure, and cost.
