Titanium vs. Chromium — What's the Difference?
By Tayyaba Rehman & Urooj Arif — Updated on April 26, 2024
Titanium is a strong, lightweight, corrosion-resistant metal used in aerospace and medical devices; Chromium is a shiny, hard metal primarily used for its corrosion resistance and as a key alloying agent in stainless steel.

Key Differences
Titanium, known for its high strength-to-weight ratio, is extensively used in applications where lightweight and durability are critical, such as in aerospace and biomedical implants. Chromium, on the other hand, is celebrated for its high corrosion resistance and is primarily used to add this property to other metals, notably in the production of stainless steel.
While titanium is less dense and has a higher melting point, chromium is often used in smaller quantities as an alloying element to improve hardness and durability of other metals. This makes chromium essential in industrial manufacturing, whereas titanium's uses are more specialized and high-end.
Titanium is biocompatible, making it ideal for medical applications such as joint replacements and dental implants. Chromium, whereas, is used in the human body only indirectly through stainless steel in medical tools and implants, highlighting its versatility but also its limitations in direct medical applications.
On one hand, titanium's resistance to corrosion by both water and chemical environments makes it suitable for marine and aerospace applications. Chromium, in contrast, is most effective in preventing rust in automotive and architectural applications when alloyed with iron and other metals.
Titanium's cost is significantly higher due to its complex extraction and processing techniques. In contrast, chromium is more abundant and cheaper to produce, which reflects in its widespread use across various industries beyond just alloying, such as in electroplating and pigments.
