Niobium vs. Titanium: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Published on February 2, 2024
Niobium is a soft, grey, ductile transition metal, often used in steel alloys, while titanium is a strong, lightweight metal known for its corrosion resistance and use in aerospace.
Key Differences
Niobium is a chemical element with the symbol Nb and atomic number 41. It's a soft, ductile metal, primarily used in alloys to improve strength, particularly in steel. Titanium, with the symbol Ti and atomic number 22, is renowned for its strength-to-weight ratio, corrosion resistance, and is widely used in aerospace, medical implants, and jewelry.
In terms of abundance, niobium is less common in the Earth's crust compared to titanium. Titanium is the ninth most abundant element in the Earth’s crust and is found in almost all rocks and sediments.
Niobium’s melting point is 2,468°C, which is lower than titanium's melting point of 1,668°C. This makes niobium less suitable for high-temperature applications where titanium excels.
Niobium is often used in superconducting magnets due to its excellent superconducting properties, whereas titanium is preferred in aerospace and biomedical applications for its strength, lightweight, and biocompatibility.
The two metals also differ in their reaction to oxygen. Niobium forms a thin oxide layer when exposed to air at room temperature, while titanium forms a more resilient oxide layer, enhancing its corrosion resistance.
