Furukawa develops high-strength copper alloy for ultra-compact connectors

ntttttttttttt

Furukawa Electric Co’s high-strength copper Corson alloy strip EFCUBE-ST is targeted for use as electrical contact materials in ultra-compact connectors mounted on thin electronic devices.

The product adopts a high-density Corson alloy that meets needs for high springing properties. It features high bending workability and a low Young’s modulus made possible by Furukawa Electric’s proprietary metal structure control technologies.

The EFCUBE-ST is targeted to replace existing titanium-copper alloy strips. The developed product features high strength based on high-concentration Corson alloy, with significantly improved bending workability, something that had been an issue with high-strength Corson alloy strips. These properties have been made possible by applying the proprietary metal structure control technologies.

The EFCUBE-ST is an alloy made by precipitation of Ni-Si compounds at a high concentration. Using the cutting-edge facilities newly introduced to Copper Strips Division (Nikko), stable structure control has become possible, enabling groundbreaking copper alloys strip to be developed.

The EFCUBE-ST has been developed to meet needs for more advanced functions than those provided by EFCUBE-820, developed last year, and is set to contribute to further reductions in the dimensions of thin mobile electronic devices.
