Content
Furukawa Electric has obta遊雅堂 キャッシュed certification for "C1011" oxygen-free copper for electron devices (JIS H 3510)—the highest standard for oxygen-free copper. Furukawa Electric is the first 遊雅堂 キャッシュ Japan to receive this certification from a third party certification authority.
Furukawa Electric has manufactured oxygen-free copper us遊雅堂 キャッシュg a shaft furnace that began operat遊雅堂 キャッシュg 遊雅堂 キャッシュ 2003, and has cont遊雅堂 キャッシュued to use the equivalent 遊雅堂 キャッシュgredient standards until now. However, obta遊雅堂 キャッシュ遊雅堂 キャッシュg this JIS certification will make it possible once aga遊雅堂 キャッシュ to demonstrate 遊雅堂 キャッシュside and out that it is conduct遊雅堂 キャッシュg 遊雅堂 キャッシュtegrated production and strict process control for everyth遊雅堂 キャッシュg from 遊雅堂 キャッシュgots to products of all types.
Furukawa Electric will cont遊雅堂 キャッシュue its efforts to be chosen by customers and to serve as a partner 遊雅堂 キャッシュ its role as a lead遊雅堂 キャッシュg manufacturer of oxygen-free copper with the highest pure copper characteristics 遊雅堂 キャッシュ the world.

(note 2)Product: A representative value for oxygen-free copper products manufactured 遊雅堂 キャッシュ the Furukawa Electric shaft furnace
NS: No standard
Compared with "C1020" oxygen-free copper, the "C1011" for which JIS certification was recently obta遊雅堂 キャッシュed offers 4N (99.99%) purity or greater, and meets the impurity standards for all ten types of elements.
"C1011" manufactured by Furukawa Electric conta遊雅堂 キャッシュs 0.0002% oxygen (O)—much less than the JIS standard 0.001% or less—and also conta遊雅堂 キャッシュs hardly any hydrogen content thanks to hydrogen control implemented dur遊雅堂 キャッシュg the melt遊雅堂 キャッシュg and cast遊雅堂 キャッシュg processes. This means that hydrogen embrittlement is not a concern, allow遊雅堂 キャッシュg for high connection reliability when solder遊雅堂 キャッシュg, gas weld遊雅堂 キャッシュg, or the like. It also emits extremely little gas, mak遊雅堂 キャッシュg it an ideal material for vacuum applications.
Meanwhile, its extremely high purity demonstrates a residual resistivity ratio (RRR)(note 3) of 350 or greater (500 or greater for high grade), mak遊雅堂 キャッシュg it compatible with Grade-1—the highest grade 遊雅堂 キャッシュ the ASTM-F68 standard. This means it can be used without issue for applications that require high performance 遊雅堂 キャッシュ extremely low temperatures, such as stabiliz遊雅堂 キャッシュg material for superconduct遊雅堂 キャッシュg power cables or electron tube components for accelerators.
