It is characterized by the magnetic properties of parallel and hardness, and its tensile strength is high up to 125-245 gigapascals, its boiling point is 3825c, its melting point is 17680c, its volume factor is 230 gigapascals, and the platinum element has a strength greater than that of iron.

Its flexibility is similar to that of ordinary gold, and the reason for calling platinum by this name is due to the Spanish word (plata) meaning (little silver), and platinum is one of the precious metals and has a special place, which made it expensive in different markets.
