عن Titanium
Titanium is a lustrous transition metal that is as strong as steel but 45% lighter. It is highly resistant to corrosion and is biocompatible, meaning the human body does not reject it, making it ideal for implants.
Uses & Applications
Aircraft and spacecraft components, medical implants, titanium dioxide pigment (paint, sunscreen), and jewelry.
حقيقة مضحكة
Titanium is one of the few metals the human body tolerates, which is why it is used for artificial joints and dental implants.
