What unique microscopic organization characteristics do tungsten alloy screws have? Core is two-phase microstructure, tungsten grains embedded in tough matrix, granting high density and hardness. First, one unique characteristic is high-density composite: density 16-19g/cm³, tungsten phase providing radiation shielding, matrix phase ensuring uniform distribution, avoiding pure tungsten brittleness. Second, balance of hardness and toughness: hardness HRC 25-35, matrix phase (like Ni-Cu) bridging grains, enhancing ductility 5%-10%, unique to other alloys’ rigidity. Third, heat resistance stability: melting point >3000°C, microstructure no phase change at high temperatures, grain boundaries strengthened, suitable for extreme environments. Fourth, corrosion and wear resistance: surface oxide layer formation, few micropores, unique acid-alkali resistance. Fifth, non-magnetic or high-conductivity options: like W-Ni-Cu non-magnetic, unique to magnetic alloys. These characteristics stem from powder metallurgy, uniform microstructure, advancing medical and aerospace applications.
