Which was the main metal used for tools and weapons by the Harappan civilization?

Harappan objects were made of stone, Shell, and metal. Copper and bronze were used to make tools, weapons, ornaments, and vessels. Gold and silver were used to make ornaments and vessels. Harappans also made stone seals. They made pots with beautiful black designs. Bricks were so well made that they had seemed to have lasted for thousands of years and were laid in an interlocking pattern which made the walls strong. About a hundred and fifty years ago, many of these bricks were taken away by engineers.

People built one or two-story houses on either side of the roads with rooms built around a courtyard. The Harappan city had a well-planned drainage system where every house had a drain connected to the street drains which further were connected to the bigger drains. The drains were also covered with the stone slabs that were laid in straight lines along with inspection holes for the cleanup purpose.
