Scientists discovered this alloy can heal tiny fractures at the nanoscale, closing cracks without any outside force or heat.

Nickel-Copper Alloy

Scientists discovered this alloy can heal tiny fractures at the nanoscale, closing cracks without any outside force or heat.

Self-Healing Aluminum

Engineered with special microcapsules, this aluminum releases healing agents when scratched—perfect for aircraft and cars.

Titanium with Smart Coating

Used in medical implants, this titanium is coated with biomimicking layers that can repair microdamage in the body.

Nano-Structured Steel

Developed for high-stress machinery, this steel can repair internal fatigue damage thanks to engineered grain boundaries.

Magnesium-Based Alloys

These experimental metals show promise in healing surface-level scratches when exposed to air, preventing corrosion over time.

World s Strangest Ancient Artifacts

Zinc Coatings with Crack Repair

Used in industrial applications, some zinc coatings can “flow” back into place, repairing damage from stress or weathering.

Shape Memory Alloys

Known for returning to original shapes after deformation, these alloys mimic healing by snapping back under heat or pressure.
