“CNT is 100 times stronger than stainless steel and six times lighter...”
“CNT is as hard as diamond and its thermal capacity is twice that of pure diamond...”
“CNT’s current-carrying capacity is 1000 times higher than that of copper...”
“CNT is thermally stable up to 4000K...”
“CNT can be metallic or semiconducting, depending on their diameter and chirality...”
However, it is important to note that all those superlative properties were predicted for an atomically-perfect ideal CNT which is far from the CNTs we are practically producing today.
