Carbon. as steel is a composition of iron with carbon and other elements such as nickel
Varies depending on the electroylite solution used (several). Can be hard to soft. Electroless Nickel is typically a more advanced form of (industrial) plating and the low phosphorus variety can achieve hardness's up to Rockwell "C" rated or HRC 60 which is very hard, like hardened steel. So, is it an industrial coating (electroless) or is it being plated over steel to receive a chrome finish (automobile bumper)? Typically the introduction of impurities into nickel actually makes it harder as pure nickel is quite soft and malleable. Hope this helps.
what is the difference between Shore-A Hardness & Barcol Hardness
no one likes your Hardness! hardness is not a good character.
Several nickel's physical characteristics:- Density: 8,908 g/cm3- Melting point: 1 455 oC- Boiling point: 2 730 oC- Crystalline system: face-centered cubic- Electrical resistivity: 69,3 nanoohm.metre- Mohs hardness: 4
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.
Mohs hardness: 6 Brinell hardness: 196 MPa.
it has to do with the hardness of the mineral which can be found by moh's scale of hardness
The Mohs hardness of sodium chloride is 2,5.
