The historical background of pure iron rivets can be traced back to the Middle Ages, when rivets, as an important metal processing technology, were widely used in the manufacture and repair of ironware. The use of rivets made ironware more durable, so they were widely used in the Middle Ages, such as in the manufacture and repair of arrows, armor, chariots, etc.
Discovery history
The history of rivets can be traced back to an earlier period. In the 1980s, an American archaeological team discovered 7 million-year-old iron rivets in a cave in Honduras, Central America. This rivet is about 35 cm long and 8 cm in diameter. The iron content is as high as 80%, the shape is regular and still usable, which shows that 7 million years ago, humans had mastered the technology of making rivets.
