Is Titanium expensive than gold?

Titanium is usually cheaper than white gold. However, because of its hardness, titanium is not as easy to work with. … In such cases, the additional labor costs may make the price of a titanium ring comparable to that of a white gold one (or even higher).

What metals are naturally in the human body?

Metals like iron (Fe), zinc (Zn) and copper (Cu) are essential to human health. We’re not quite Iron Man, but metals are intricately entwined with our bodies. They make vital functions like respiration, circulation and reproduction possible.
