Titanium is known for its excellent corrosion resistance due to its ability to form a thin, protective oxide layer on its surface when exposed to oxygen. This oxide layer is very stable and prevents further metal oxidation, which means that titanium is highly resistant to rust and corrosion.

Titanium is one of the most corrosion-resistant metals, and it is often used in harsh environments where other materials would rust or deteriorate. This makes it a popular choice for applications in aerospace, marine, and medical, where high levels of corrosion resistance are essential.

However, while titanium is highly resistant to corrosion, it is not entirely immune to it. In certain extreme conditions, such as exposure to high concentrations of acids or alkalis or certain types of bacteria, titanium can corrode. But overall, titanium’s corrosion resistance is one of its most valuable properties, and it is a highly sought-after material for many applications.
