The hardness of bronze is also higher than wrought iron allowing better tools to be made.
What was bronze mainly used for originally?
From a very early date bronze was used mainly for casting. Because it is so brittle, it has only rarely been hammered or chased; brass or copper were preferred for such work because they are more malleable. Down to the Middle Ages, bronze was cast by the cire perdue, or lost-wax, method.
