3.5
Yes, brass is an alloy made of copper and zinc; the proportions of copper and zinc can be varied in the alloy to create a range of brasses with different properties (e.g. hardness, corrosion resistance) that are needed for different applications.
no one likes your Hardness! hardness is not a good character.
The hardness of Limonite is 4 t0 5.5 on the mohs hardness scale.
it has to do with the hardness of the mineral which can be found by moh's scale of hardness
Pure materials, especially minerals, are measured on a hardness scale. There are three basic tests: indentation hardness, scratch hardness and rebound hardness. See Wikipedia

On the moh's hardness scale: 3-4

The Mohs scale of hardness determines a mineral's hardness by comparing it to the hardness of common household objects: 1. streak plate (unglazed porcelain)= 6.5 2. glass, masonry nail, knife blade= 5.5 3. wire (iron) nail= 4.5 4. brass (wood screw, washer)= 3.5 5. copper coin (penny)= 3.0 6. fingernail= 2.5

The hardness of conundrum is 9 on the Moh's hardness scale
The hardness of Limonite is 4 t0 5.5 on the mohs hardness scale.
I don't found the Mohs hardness of plutonium but: - the Brinell hardness is 242 at r.m. - the Vickers hardness is 255 at r.m. After a hardness conversion chart an equivalent Mohs hardness may be 3,7.
Marble ranges from 2-5 on Moh's scale.add. There are several hardness scales other than Mohs, which is an arbitrary scale of hardness. .There is a Janka scale for wood, but be careful of the units used.There is a Rockwell scale for the Hardness of steel. This measurement leaves little mark (impression).There is a Brinell hardness scale which forces a hard steel ball into the test piece. This method leaves an impression on the test piece, but can be calibrated for steel, wood, and other metals.The Vickers Hardness test uses a diamond indenter, and is often used for hard materials such as case-hardened material.[Rockwell, Brinell, and Vickers have tables of equivalence.]And, last of all is a hardness test for paints and similar. This test, BS3900 - E19, ISO 15184, uses ordinary pencils of various hardness to determine the hardness of the paint film.
Mohs hardness: 6 Brinell hardness: 196 MPa.
