C19900 is a typical time hardening high-strength and high elastic copper alloy with Ti and other trace elements added to copper as the matrix. Its mechanical and physical properties are comparable to those of beryllium copper alloy. It can be used for manufacturing application connectors, connecting components, electrical springs, internal spring plates of high-voltage terminals, etc
