Copper Alloys for SIM Card Connectors

Backgrounds and Trends

Lower profiles are increasingly demanded for the slots used to insert communication SIM cards, or SD memory cards used to transfer and store music, images, text, and other data, as smartphones and other equipment equipped with such slots become lighter and thinner.

Material Requirements

Alloys with high yield strength and high workability are demanded so that even thin materials can maintain the necessary contact pressure.
We have the lineup of materials detailed below to meet these demands. These alloys are already in wide use, mainly in smartphones.
