The fragmentation bomb is primarily made of which material?

The fragmentation bomb is primarily made of spirally wound spring steel because this material is specifically chosen for its ability to create lethal fragments upon detonation. The design allows the bomb to fragment effectively, ensuring that the pieces are propelled outward at high velocities, thereby maximizing the bomb's effectiveness in incapacitating or damaging targets over a wider area.

Spirally wound spring steel not only provides durability and structural integrity under explosive conditions, but it is also capable of forming sharp, lethal fragments that can penetrate targets effectively. This characteristic is critical in fragmentation bombs, as the goal is to distribute destructive force across a larger target area.

Materials like aluminum, plastic, or composite materials may have their own applications in munitions, but they do not offer the same combination of strength and fragmenting capabilities that spirally wound spring steel does.
