What is the toughest material?
Diamond
Diamond is the hardest known material to date, with a Vickers hardness in the range of 70–150 GPa. Diamond demonstrates both high thermal conductivity and electrically insulating properties, and much attention has been put into finding practical applications of this material.
What is the strongest item in the world?
Diamond is the hardest substance found on earth in so many natural forms, and it is an allotrope of carbon. The hardness of diamond is the highest level of Mohs hardness – grade 10.
What is the hardest thing to break?
Although it holds the hardness record, diamond is not tough—if you smash it with a hammer, it will fracture and break. Diamond, pictured here in an uncut, unpolished state, is the hardest known material.
What is the strongest man made material?
Graphene
Graphene. Topping the list, graphene is the strongest materials known to humans. The transparent material is composed of a single layer carbon atom arranged in a triangular lattice and it’s the basic structural element in charcoal, graphite and carbon nanotubes.
What is an unbreakable material?
Graphene, even in an imperfect form, remains the strongest material in the world, according to new research from Columbia University, which found that the single layer of latticed carbon atoms is virtually unbreakable even when stitched together like a quilt.
What’s harder than a diamond?
boron-nitride
Moissanite, a naturally occurring silicon-carbide, is almost as hard as diamond. It is a rare mineral, discovered by the French chemist Henri Moissan in 1893 while examining rock samples from a meteor crater located in Canyon Diablo, Arizona. Hexagonal boron-nitride is 18% harder than diamond.

What metal is hardest to break?
What Is the Strongest Non-Alloy Metal in the World?
- Tungsten has the highest tensile strength of any natural metal, but it’s brittle and tends to shatter on impact.
- Titanium has a tensile strength of 63,000 PSI.
- Chromium, on the Mohs scale for hardness, is the hardest metal around.
What is the strongest theoretical material?
Graphene remains the strongest material ever measured and, as Professor Hone once put it, so strong that “it would take an elephant, balanced on a pencil, to break through a sheet of graphene the thickness of Saran Wrap.”
What is the most unbreakable material in the world?

Can diamonds be melted?
In the absence of oxygen, diamonds can be heated to much higher temperatures. The ultimate melting point of diamond is about 4,027° Celsius (7,280° Fahrenheit).
How does Super Steel get its toughness?
The super steel is made using a new deformed and partitioned method (D&P), and it gets its toughness from a unique design feature. When a fracture appears at the surface of the material, multiple tiny cracks form below it.
What are the different types of superhard materials?
Superhard materials can be generally classified into two categories: intrinsic compounds and extrinsic compounds. The intrinsic group includes diamond, cubic boron nitride (c-BN), carbon nitrides, and ternary compounds such as B-N-C, which possess an innate hardness.
What can the new super steel be used for?
The team says that the new super steel could find use in high-strength bridge cables, bullet-proof vests, and car springs, among other applications. “We have made a big step closer to industrializing the novel super steel,” says Huang Mingxin, lead author of the study.
How are the properties of Super Steel balanced?
Now, engineers have developed a new type of “super steel” that defies this trade-off, staying strong while still resisting fractures. For materials like steel, there are three main properties that need to be balanced – strength, toughness and ductility. The first two might sound like the same thing, but there’s an important difference.
