Which is the strongest metal know to man ?
Titanium is the strong, light metal. It is as strong as steel and twice as strong as aluminum, but is 45% lighter than steel and only 60% heavier than aluminum. Titanium has the highest strength to weight ratio of any natural metal known to man.
Titanium is not easily corroded by sea water and is used in propeller shafts, rigging and other parts of boats that are exposed to sea water.
Titanium and titanium alloys are used in airplanes, missiles and rockets where strength, low weight and resistance to high temperatures are important.
Since titanium does not react within the human body, it is used to create artificial hips, pins for setting bones and for other biological implants.
Unfortunately, the high cost of titanium has limited its widespread use.
