the structure of nanotubes are carbon atoms joint together covalently to form a long tube.
It depends on the structure.
Nanotubes are typically made from carbon atoms arranged in a cylindrical structure. Carbon nanotubes can have different properties depending on their structure and can be single-walled or multi-walled. They are known for their strength, flexibility, and thermal conductivity.
According to Wikipedia: "The bulk modulus of superhard phase nanotubes is 462 to 546 GPa, even higher than that of diamond (420 GPa for single diamond crystal)." Note that diamonds are natural minerals; nanotubes are fabricated, making diamond the hardest known natural substance. You can read more about nanotubes, below.
Carbon can form diamond, graphite, amorphous carbon, nanotubes, fullerenes, etc.

nanotubes
Yes, carbon nanotubes can conduct electricity due to their unique structure which allows for excellent electron transport. They are considered to be one of the best conductive materials known, with properties similar to metals.
Tiny hollow tubes made up of carbon atoms are called carbon nanotubes. They have exceptional strength, electrical conductivity, and thermal conductivity due to their unique structure, making them promising materials for various applications in nanotechnology, electronics, and materials science.
Strength:Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively.Hardness:Standard single-walled carbon nanotubes can withstand a pressure up to 25 GPa without deformation.
Although there are numerous instances of people observing carbon nanotubes, most literature credits Sumio Iijima as the discoverer of carbon nanotubes.
