No, iron is generally considered a soft magnetic material. Soft magnetic materials are easily magnetized and demagnetized, meaning they do not retain their magnetism well after an external magnetic field is removed. This property makes pure iron suitable for applications like electromagnets and transformer cores, where the magnetic field needs to be turned on and off or reversed frequently. Hard magnetic materials, on the other hand, are difficult to magnetize but retain their magnetism strongly, making them suitable for permanent magnets. 3 done, 2 left today. You're making progress.
