【Copper Packing Selection Guide】What is the difference between C1100 and C1220?
Introducing Daiko's processing technology that prevents leaks with "yakinamashi."
In the world of industrial gaskets, "copper" is an essential material for handling "heat" and "electricity." However, there are two main grades of copper gaskets: "C1100 (tough pitch copper)" and "C1220 (phosphorus deoxidized copper)," and choosing the wrong one can lead to issues such as "cracking at the weld" or "not achieving the expected conductivity." In this article, Daiko Co., Ltd., a specialized manufacturer of industrial gaskets, explains the differences between these two copper grades and the importance of "annealing (softening treatment)" that dramatically enhances the sealing performance of copper gaskets. *For more detailed information, you can view the related links.
