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 mineral would have a hardness between 5.5 to 6 on the Mohs scale. This suggests that it is harder than glass (hardness of 5.5) but softer than an iron nail (hardness of around 5.5 to 6).

What is Mohs hardness of Barium Sulfate

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 mineral would have a hardness between 5.5 and 6.5 on the Mohs scale. It cannot scratch glass (hardness of about 5.5) but can scratch an iron nail (hardness of about 4). This places it in the range of minerals like orthoclase feldspar or apatite.
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
Pure iron is relatively soft and easily worked (malleable). Iron heated to high temperatures and alloyed with carbon and other elements is called steel, which can be made extremely hard and durable, but not easily worked.
the hardness of iron decreases with increase in brittleness in general..however when the temp is increased, the elasticity increases and the brittleness reduces, it continues to show the increasing trend in hardness until a transition temperature, after which the hardness starts decreasing again.
