What’s the difference?

Grade 5 titanium and Grade 5 titanium alloy are generally the same material. The difference is mainly how the terms are used, rather than a difference in composition or performance.

 

1. Titanium (pure titanium)

ASTM B381 Grade 5 Ti6al4V Titanium Billet for Chemistry - Titanium Billet and Gr. 5 Titanium Billet

Technically refers to commercially pure titanium, such as Grades 1–4.

  • Generally softer and more ductile than Grade 5.

  • Excellent corrosion resistance.

  • Often used in chemical processing, marine applications and medical products.

     

2. Grade 5 titanium alloy (Ti-6Al-4V)

Norvik – Industrial Tooling

A titanium alloy containing aluminium and vanadium to improve its mechanical properties.

  • High strength-to-weight ratio.

  • Stronger than commercially pure titanium.

  • Excellent corrosion resistance.

  • Good fatigue performance and heat resistance.

  • Commonly used in aerospace, motorsport and high-performance engineering.
