You have heard about a distant era in the history called the stone Age. It was indeed a stepping stone in Man’s epic journey towards civilization. But this journey took a giant strides when Man discovered an important group of elements in nature-metals. When copper became part of primitive man’s life, the Stone Age faded into oblivion, and another important era ushered in-The Bronze Age.This was followed by the Iron Age, when weapons and tools came to be made of iron.
For ages,metals have faithfully served humanity in all its endeavors to conquer the elements, unravel the mysteries of Nature, and build powerful machines and installations. It was the tempting glory of the yellow metal,gold,that led to numerous blood sheds in history. Metal alloys like steel have been an indispensable material in construction since the Industrial revolution.
