The density advantage of tungsten beads is mainly reflected in the multifaceted performance improvements brought about by their high density.
I. Density Values and Material Comparison
The density of tungsten beads typically ranges from 15.8 to 19.35 g/cm3, with the specific value depending on the alloy composition and manufacturing process. This density is significantly higher than common metals such as steel (7.85 g/cm3) and lead (11.34 g/cm3), and even approaches that of depleted uranium (approximately 19.05 g/cm3). This high density allows tungsten beads to have a greater mass for the same volume, which is the basis of their core advantage.
II. Military Application Performance
Enhanced Penetration: In the military field, tungsten beads are often used as cores for armor-piercing projectiles or pre-fragmented shotgun shells. The high density of tungsten beads endows them with powerful kinetic energy, allowing them to maintain good integrity upon impact with a target, resisting deformation or breakage, thus enabling more effective penetration of armor or hard objects.
Enhanced Stability: The high density of tungsten beads also contributes to better stability during flight, reducing the impact of air resistance on the trajectory and improving shooting accuracy. This is crucial for military missions requiring precision strikes.
III. Advantages in Industrial and Civilian Applications
Counterweight Applications: In industrial applications, the high density of tungsten beads makes them an ideal material for counterweights. For example, golf club head weights improve shot accuracy by adjusting the center of gravity; fishing weights utilize their high density to increase casting distance; and tungsten beads in watch balance wheels enhance the stability of mechanical devices.
High Temperature and Corrosion Resistance: In addition to their high density, tungsten beads also possess excellent high temperature and corrosion resistance. This allows them to maintain structural stability even in extreme environments, such as counterweights on oil drilling platforms to withstand the high pressure environment downhole, and shock-absorbing counterweights in precision instruments to improve equipment stability.
IV. Environmental Protection and Safety
Compared to traditional lead balls, tungsten beads are non-toxic and pollution-free, making them safer and more environmentally friendly. In flow meter components requiring high corrosion resistance, the corrosion resistance of tungsten beads also gives them potential application value.
