No, iron is harder than potassium. Iron is a metal with a higher Mohs hardness rating than potassium, which is a soft alkali metal.
Zinc is considered a hard metal; its hardness is similar to that of Iron.
It's actually a rather difficult question to answer as iron can be forged in a number of different ways, each giving a different hardness. I've attached a link to a site giving different hardness values for some treatments of grey iron.
Yes, hardness is a physical property of a metal that describes its resistance to deformation or scratching. It is an important characteristic that can determine the metal's suitability for specific applications. Hardness can be measured using various methods such as Brinell hardness, Rockwell hardness, or Vickers hardness tests.
no, aluminum is softer.
Ferro-ferrous oxide. Fe3O4 Cubic Hardness 5.5-6.5 streak is black.
It depends on the deposit. What deposit are you talking about? What measure of hardness are you after? e.g. UCS, Moh's Hardness Scale e.t.c. On moh it is 4 Brinnel hardness it is 490
It would have to be 5.0 because glass has a hardness of 5.5 and an iron nail has the hardness of 4.5
No, emerald is not stronger than iron. Emerald is a type of beryl and has a hardness of about 7.5 to 8 on the Mohs scale, while iron has a hardness of around 4.0 to 5.0. Additionally, iron is a metal, making it much more durable and capable of withstanding stress compared to emerald, which is a brittle gemstone. Therefore, in terms of strength and durability, iron is significantly stronger than emerald.
Gold is considered a relatively soft metal. It has a Mohs hardness of about 2.5 to 3, which means it can be scratched easily compared to harder metals like iron or steel.
It would have to be 5.0 because glass has a hardness of 5.5 and an iron nail has the hardness of 4.5
