Titanium

Definition

Titanium is a strong, lightweight metal known for its excellent corrosion resistance and high strength-to-weight ratio. It is commonly used in aerospace, medical implants, and high-performance automotive applications due to its ability to withstand extreme temperatures and environments while maintaining structural integrity.

5 Must Know Facts For Your Next Test

1. Titanium has a melting point of about 1,668 °C (3,034 °F), making it suitable for high-temperature applications.
2. It is non-toxic and biocompatible, which makes titanium ideal for medical implants like bone plates and dental fixtures.
3. Titanium can be challenging to machine due to its toughness and work hardening properties, requiring specialized tools and techniques.
4. The most common titanium alloy is Ti-6Al-4V, composed of 90% titanium, 6% aluminum, and 4% vanadium, known for its strength and lightweight characteristics.
5. Titanium's natural oxide layer protects it from corrosion in harsh environments, which is why it is favored in marine applications.
