Seungja Chongtong is a small korean tubular arm that made by particular arm-making way imitating a chinese arm. This study organizes scientific analysis results with results of inscriptions reading of Seungja Chongtong in theCentral museum of Kyunghee University. Three of Seungja Chongtongs are made with Cu-Sn-Pb ternary alloy which is not much differ in contents and the results of microstructure analysis of Seungja Chongtong 1 which could investigate a microstructure among the Chongtongs were found out that Seungja Chongtong is made by general casting, with no evidences of an additional heat-treatment and tempering. Furthermore, in results of lead isotope ratio analysis to find out a source of lead using during the production of Seungja Chongtong, It seems that Seungja Chongtong is made with a lead ore from northern Gyeongsangbuk-do Province and southern Gangwon-do Province called Korea southern zone 2 area.
