Bullets and X-ray shields are also made of this

Also photographic and X-ray film. This has the highest known electrical and thermal conductivity of all metals.

Also phone and electric car batteries, and used to make hard alloys used in jet engines and drill bits

Used also in bullets, and in the hardening of other metals

Also dental implants, jet engines and space shuttle parts

Cosmetics too, and low-melting-point alloys used in fire detection and extinguishing

Also general anaesthetics and eye surgery lasers

Is commonly used in paint as well

X-rays of the digestive system also use this

Commonly used in chips in electronic devices like computers

Nodules of this element cover about 70% of the ocean floor
