For studying of bronze culture and making technique of related artifacts in western Yunnan Province, 17 samples excavated from stone coffin tombs in Xiangyun county Yunan province were analysed by SEM and metallographic analysis. The experimental results show that the most of artifacts are copper, only a small number of those are alloy Cu-Sn. The making technique of these artifacts is relatively simple, mainly casting and cold working after casting, etc. Three chimes are alloy of Cu-Sn and components of tin with geometric increase which related to require of the acoustic effect. The spears buried in the tombs can be divided into two categories, utility wares and funerary objects by the identity of the owner of the tombs. The spades, awls and chisels are inferred as utility wares which have used traces and been processed by cold working. The bronze hoes, one kind of farm tools, were only used as funerary objects instead of utility wares which is the evidence of local funeral customs in western Yunnan Province. Analysis shows that the making technique of those bronze and copper wares depends on the application of those objects. This paper has a certain significance of studying bronze culture and metal technique in western Yunnan Province.
