Ask most people what the hardest material on Earth is and they will probably answer “diamond“. Its name comes from the Greek word ἀδάμας (adámas) meaning “unbreakable” or “invincible” and is from where we get the word “adamant”.
What are some unbreakable materials?
The World’s Strongest Stuff
- Diamond. Unmatched in its ability to resist being scratched, this much-loved gemstone ranks the highest in terms of hardness.
- Graphene.
- Spider silk.
- Carbon/carbon composite.
- Silicon carbide.
- Nickel-based super-alloys.
Is there anything in the world that is unbreakable?
It’s a tardigrade—the most ‘indestructible’ animal on Earth. Also called water bears, tardigrades can survive up to 30 years without food, live in volcanoes, and endure the vacuum of space.
What material is hardest to break?
Steel and titanium are the hardest to break, because they are both tough and ductile. Both have a typical Ultimate Yield Strength (UYS) of about 63,000 psi, although some alloys of steel can have much higher values of UYS.
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 a strong material?
Graphene
Bags made of graphene, which can hold about 2 tons of weight, are by far the strongest material known.
Is diamond the strongest?
While diamonds are classically viewed as the hardest material found on Earth, they are neither the strongest material overall nor even the strongest naturally occurring material.
What object can not break?
Elements are pure substance that cannot be broken down into simpler substances by chemical or physical means. Each element has unique physical and chemical properties.
What’s something that doesn’t break?
If something is so strong that it is impossible to damage it, you can say that it is indestructible. Titanium is virtually indestructible.
What things Cannot break?

- The Unbreakable Umbrella. Source and Image: unbreakableumbrella.com.
- Tungsten Rings.
- The Indestructible Watch.
- Round Body Padlocks.
- Indestructible Toilet Seat.
- Indestructible Tires.
- Indestructible Haircut Kit.
Are Diamonds brittle?
Diamonds are no longer the world’s hardest substance
“Whilst its cubic arrangement makes a diamond very hard, it is also somewhat brittle,” says Professor Phillips. “This is because there are weaknesses along the cubic planes.
What’s harder than diamonds?
(PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond.
What is the strongest material in the universe?
nuclear pasta
These simulations stretched and squeezed the pasta to calculate its strength and study how it breaks. They found that nuclear pasta is the strongest material in the universe, which makes it possible for neutron star crusts to have crustal mountains that are tens of centimeters high.
Is spider web the strongest material?
Spider silk is said to be one of the strongest, toughest materials on the Earth. Now engineers at Washington University in St. Louis have designed amyloid silk hybrid proteins and produced them in engineered bacteria.
What is the strongest clear material?
polycarbonate
Acrylic and polycarbonate are transparent plastics that are stronger than many other clear plastic sheet materials and are often used in architectural glazing applications when transparency and superior mechanical properties are required.
Can a hard material be tough?
However, while a diamond is hard it is not tough. If you took a hammer to a diamond it would shatter, which demonstrates that not all materials that are hard are also tough. In the world of metal tools, drill bits and grinding discs must be extremely hard to be able to handle high amounts of friction.
Is diamond the strongest material?
The outermost shell of each carbon atom has four electrons. In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal. It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on Earth.
Are diamonds bulletproof?
It doesn’t seem unreasonable to wonder whether diamonds are bulletproof, since diamond is the world’s hardest natural material. Diamonds are not however bulletproof in general, as while they are hard, they are not particularly tough and their brittleness will cause them to shatter when struck by a bullet.
Can steel cut diamond?
Using these imperfect stones as cutting grit belies the main theory: only a diamond can truly cut another diamond. Diamonds are cut with specialized tools that make use of diamond tipped phosphor bronze or diamond dusted steel blades.
Can diamonds melt?
In the absence of oxygen, diamonds can be heated to much higher temperatures. Above the temperatures listed below, diamond crystals transform into graphite. The ultimate melting point of diamond is about 4,027° Celsius (7,280° Fahrenheit).
What causes material to break?
The factors that govern how something breaks are firstly, how strong the bonds in the material are and secondly (and more importantly) what defects are present in the material. 2. Materials break as they are deformed past their breaking points. Deformation tends to occur by dislocations as defects are propagated.
