Lightweight and high-strength: The density is only about 1/4 - 1/5 of that of steel and about 2/3 of that of aluminum, but the tensile strength can reach 3 - 5 times that of steel. The specific strength (strength/density) far exceeds that of traditional materials, enabling it to reduce the structural weight while ensuring the load-bearing capacity.
High stiffness and fatigue resistance: It has a high elastic modulus (about 1/2 that of steel, but with a lower density and better specific stiffness). It is not prone to fatigue deformation or fracture when subjected to alternating loads for a long time, and has a long service life.
