In recent decades, carbon aerogels have been widely explored by using graphitic carbons and soft carbons, which show advantages in superelasticity. These elastic aerogels usually have delicate microstructures with good fatigue resistance but ultralow strength. Hard carbons show great advantages in mechanical strength and structural stability due to the sp3 C-induced turbostratic “house-of-cards” structure. However, the stiffness and fragility clearly get in the way of achieving superelasticity with hard carbons. Up to now, it is still a challenge to fabricate superelastic hard carbon-based aerogels.

One of the key advantages of thread carbide extension rods is their exceptional hardness. Made from a combination of tungsten carbide and cobalt, these rods possess a Rockwell hardness rating of up to 93 HRC, which is significantly higher than conventional steel or aluminum counterparts. This superior hardness allows them to maintain their sharpness and cutting ability even after extended use, reducing the frequency of sharpening and maintenance downtime.
