Advanced Technology now available
CCB has many advantages, such as a thermal expansion coefficient of 17, and a density of 18.98 g/cm3, almost as much as depleted uranium, allowing for solid grounding without bolts.
Prior to now, CCB had only been used in the most secret aviation and space applications, such as the still classified KHD-18 spy satellite and the LB3 Keystone light bomber. It's used all over Area-51 and has been identified as the cause of 42% of UFO sightings. (I can't remember if I'm allowed to say that or not)
For the civilian world, CCB is ideal for mobile* and IOT (Internet of things) devices
