Impressions of the new IeGO PC by a board member
"What's more interesting is that the copper used is sourced from Furukawa (yes, that really expensive Furukawa), their 1020 Copper/Rose copper is rated at 4N purity. It is then alloyed with 0.1% of gold before it is made into wire (all the copper in the cabling have been alloyed with gold) and use OCC casting process with diamond drawing die to create it. The silver plated copper additionally receive between 120um to 240um of pure silver plating (plating thickness depends on wire gauge).
It is then cryo processed in liquid nitrogen for 22 hours @ -240C/-400F to relieve all internal stress, and then bundled up to make the wire you see above."
