Copper Alloys for USB Connectors
Backgrounds and Trends
For some time, USB connectors have been used to connect peripheral devices to smartphones and PCs. Recent USB standards are more advanced than before, requiring support for high-speed data transfer and quick charging.
Material Requirements
For USB Type-C, high yield strength is necessary in the plug contacts to maintain connection reliability, and high electrical conductivity is needed to handle large current flows. In receptacle contacts too, high electrical conductivity is required for large current flows. We recommend the materials detailed below for each kind of contact. With a wide-ranging materials lineup, we are able to meet the diverse needs of customers.
