In brinell scale ,the hardness value is 180
iron with 1.5% of carbon by volume or less is called carbon steel and above 1.5% it is called cast iron, hardmess increases with the carbon % i.e. cast iron is harder than carbon steel
if the cast iron consists of carbon in its free state then it is called a grey cast iron mechanical properties of grey cast iron tensile strength - 270 - 400 N/mm2 Brinell hardness number - 207 - 320 Modulus of elasticity - 1*105 N/mm2 poisson's ratio - 0.23 modulus of rigidity - 0.350 * 105
If the pipe is No Hub cast Iron you can use a mission cap If the cast Iron is bell then you caulk in a cast iron plug If the cast iron is a spigot end you get a transition coupling either standard weight CI or extra heavy and then use a cast iron cap in the transition coupling

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.
There are many different iron ores, so each would have a different hardness.
no, aluminum is softer.
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

The hardness of glass is around 6, and the hardness of iron is about 5. So your mineral is probably around a 5.5.
The amount of carbon in iron is greater than 2 percent. Iron, steel is more difficult. Steel is more resistant to damage from iron.

Grey cast iron, grades are FG300, FG350 and FG400 for example (grades range from 150 to 500) refers to hardness and carbon content
