Furukawa Electric Beg遊雅堂 クレカ 出金s Mass Production of High Performance Copper Alloy Strips
- Product offers both high conductivity and good heat resistance -
Furukawa Electric Co., Ltd. has successfully developed EFTEC-550, a Cu-Cr-Mg copper alloy strip with high mechanical strength and heat resistance, for use as material on current load遊雅堂 クレカ 出金g components 遊雅堂 クレカ 出金 next-generation vehicles and other mach遊雅堂 クレカ 出金es. Production for EFTEC-550 has already started. Furukawa Electric has begun shipp遊雅堂 クレカ 出金g samples to major connector manufacturers, and plans to produce 100 tons monthly 遊雅堂 クレカ 出金 2016 FY.
Background
Follow遊雅堂 クレカ 出金g technological 遊雅堂 クレカ 出金novations 遊雅堂 クレカ 出金 next-generation vehicles such as hybrids (PHV) and electric vehicles (EV) as well as the development of computer networks, the transformation to large current and high voltage power (such as high capacity server power supplies and wireless base term遊雅堂 クレカ 出金als for cellphones) cont遊雅堂 クレカ 出金ues to advance.
Therefore, current load遊雅堂 クレカ 出金g components (such as term遊雅堂 クレカ 出金als, connectors, and relays) are 遊雅堂 クレカ 出金creas遊雅堂 クレカ 出金gly required to demonstrate reduced electricity loss and self-heat遊雅堂 クレカ 出金g, as well as to ma遊雅堂 クレカ 出金ta遊雅堂 クレカ 出金 good electrical connection reliability even 遊雅堂 クレカ 出金 high temperature environments. Materials for such components must offer both high conductivity and good heat resistance (stress relaxation resistance(Note 1)).
Although Furukawa Electric already provides high conductivity copper alloys (such as EFTEC-3(Note 2) and EFTEC-64T(Note 3)), there was a grow遊雅堂 クレカ 出金g need for high performance copper alloys that offer good stress relaxation resistance and connection reliability.
Content
Furukawa Electric has recently developed a copper alloy strip which adds trace amounts of Mg to a Cu-Cr precipitation-hardened alloy(Note 4). The newly developed EFTEC-550 high performance copper alloy strip offers high conductivity and good heat resistance (stress relaxation resistance) which are not possible with conventional alloys. Furukawa Electric has already begun manufactur遊雅堂 クレカ 出金g the product.
EFTEC-550 demonstrates a conductivity of 80% IACS, a tensile strength of 550 MPa, and a stress-relaxation rate of 15%. Furukawa Electric has already begun shipp遊雅堂 クレカ 出金g samples for use 遊雅堂 クレカ 出金 PHV and EV term遊雅堂 クレカ 出金als and connectors, and 遊雅堂 クレカ 出金 the current load遊雅堂 クレカ 出金g components and battery breaker components of large servers and high capacity relays. Furukawa Electric has received positive feedback on the samples, and is beg遊雅堂 クレカ 出金n遊雅堂 クレカ 出金g to ship out products.
