In our study, we carried out structural and compositional analyses on nine bronze samples excavated from the Wangjinglou Site using metallographic microscopy and scanning electron microscopy. Only tools and weapons were found in this batch of bronzes. The results reveal the diversification of the bronze materials and the non-unitary processing modes of the bronzes. The bronzes from the Wangjinglou Site belong to the early use stage of copper alloy and the results show that the ancients there had accumulated experience in forging technology.
