What is the hardest material known to man?
Source: English Wikipedia.
(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 weakest fiber?
WoolWool is the weakest natural fibre while silk is the strongest natural fibre.
What is the strongest natural material in the world?
spider silkSome scientists claim spider silk, and by extension sea snail teeth, are stronger than metals such as steel. Limpet teeth has displaced spider silk as the strongest natural material in the world, according to new research from the University of Portsmouth.
Is Diamond stronger than titanium?
Titanium is not stronger than a diamond. In terms of hardness, Titanium is not harder than a diamond either. … Diamond strength is around 60 GPa. As for the hardness scale, titanium is 36 Rockwell C, while diamond is 98.07 Rockwell C.
Is Diamond stronger than steel?
Therefore diamond can withstand more than iron/steel. The data you quote shows that diamond is stronger than steel, but strength isn’t the same as brittleness (or, indeed, stiffness). … Steel can deform a lot before it breaks, diamond can’t and so diamond is more brittle than steel but much stronger.
What is the strongest fiber in the world?
DyneemaLearn More about Dyneema, the World’s Strongest Fiber The seemingly unfeasible fabric possesses around 15x more tensile strength than steel by weight, yet can still float on water, making it the strongest and most durable lightweight fiber in the world.

What is the strongest metal known to man?
tungstenIn terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi). But in terms of impact strength, tungsten is weak — it’s a brittle metal that’s known to shatter on impact. Titanium, on the other hand, has a tensile strength of 63,000 psi.
What is the toughest material on earth?
NacreNacre, the rainbow-sheened material that lines the insides of mussel and other mollusk shells, is known as the toughest material on Earth.
Is Obsidian stronger than diamond?
Surprisingly, the edge of a piece of obsidian is superior to that of a surgeon’s steel scalpel. It is 3 times sharper than diamond and between 500-1000 times sharper than a razor or a surgeon’s steel blade resulting in easier incisions and fewer microscopic ragged tissue cuts. Obsidian is found all over the world.
What is the weakest thing on earth?
According to the Mohs scale, talc, also known as soapstone, is the softest mineral; it is composed of a stack of weakly connected sheets that tend to slip apart under pressure.
