| Abstract: | This article focuses on the good mechanics feature and environment protection of Cu-Ni-Sn Alloy which can be expected to be a new type of Copper alloy with high elastic feature to replace current Cu-Be Alloy and to be widely applied in making various kinds of connectors,spring parts,switches and etc.The current research status and manufacturing technology at home and abroad is stated in the article.The influence to the microstructure and properties of alloy by Ti, Si, Cr, Al, Co, Fe, In, and Mn is analyzed.It is pointed out that the study and research to Cu-Ni-Sn Alloy should be focused on lowering the unevenness of chemical distribution in the alloy, optimizing preparation process and adding in a little other chemical elements so as to enhancing the alloy feature. |
