Materials
The first plate armour was that of bronze, being worn by elite soldiers in Greek armies in particular. Bronze, whilst easier to work with, was much less commonly available (requiring copper and tin, which are almost never found in close proximity). Iron was, however, adequate enough for the task, eventually becoming more popular because of its strength as well as its far greater availability to be used in the advanced militaries of Europe and the Middle East.
Gradually methods of making steel were perfected and steel replaced iron in most capacities except munition armour. Steel was continually being made stronger and thicker to protect from bullets but eventually the needed protection was too heavy and expensive for most troops.
In the 20th century titanium and super-hardened "ballistic steel" came to be used for trauma plates. Eventually ceramic plates made from aluminium oxide and silicon carbide were introduced as well.

Famous quotes containing the word materials:
“If only it were God’s will that printed and written materials have as much influence on the people as the princes and their censors fear! Considering the countless good books we have, the world would have changed for the better a long time ago.”
—Franz Grillparzer (1791–1872)
“Realism to be effective must be a matter of selection. ... genius chooses its materials with a view to their beauty and effectiveness; mere talent copies what it thinks is nature, only to find it has been deceived by the external grossness of things.”
—Julia Marlowe (1866–1950)
“Though the hen should sit all day, she could lay only one egg, and, besides, would not have picked up materials for another.”
—Henry David Thoreau (1817–1862)
