Is a stone harder than metal?

Answer 1

Yes

Answer 2

i believe teeth are harder than metal. Are teeth harder harder than bones? And does it depend where in the body the bones are?

I heard that bones are harder than cement and teeth are made from the same material as bones, so I don't think they are harder than metal.(If cement is harder than metal that is)

Answer 3

No. The outer structure of bones is mainly calcium and phosphorous, 2 of the main elements recommended for a good diet. Inside the bones is the marrow, a spongy porous material that is either muscular or fat and generates blood products (red and white blood cells.) This area is rich in blood vessels so you would find many proteins, iron, potassium, sodium, water and more here. The iron content of this area is high for the body BUT not near enough to say "it's made of metal."

Answer 4

It depends on the type of steel. Bone is not harder than reinforced tempered steel, but bone is harder than other types of steel. It all depends on the type of steel you are comparing bone against.

yes

Answer 5

Metal is harder than stone.

<><><>

Depends. Which rock, and which metal? Quartz is MUCH harder than copper, brass, tin, etc. Mercury, which is a LIQUID metal at room temperature is not as hard as wood.

Answer 6

It's stronger than a diamond, but not harder than metal.

answ2. Moh's Hardness scale is used to compare the hardness of various natural things. It is an arbitrary scale, with diamond at 10. [But some diamonds are harder than others.]

Man-made materials such as Tungsten carbide and Boron nitride are almost as hard as diamond, and are used in cutting or drilling very hard rocks.

Tempered steel is quite hard, but rocks such as granites are pretty hard on hardened steel drills.

Many stones are harder than many metals.
