The projectiles used in hypersonic railguns are typically made from dense, durable materials that can withstand the extreme stresses of high-speed flight and impact. Common materials include:

Tungsten: Known for its high density and melting point, tungsten is often used in penetrators and armor-piercing rounds.

Depleted Uranium (DU): DU is also very dense and has self-sharpening properties upon impact, making it effective for armor penetration.

Alloyed Steel: Specially treated steel alloys can be used to withstand the electromagnetic acceleration and the forces encountered at hypersonic speeds.

Composite Materials: Some advanced railgun rounds may use composites that combine metal and ceramic components.

The projectile is typically solid (non-explosive) and relies entirely on its speed and mass to deliver destructive kinetic energy upon impact. This is different from conventional artillery, which often relies on explosives to enhance damage.
