Rusted cast iron.
Rusted iron is generally weaker than non-rusted iron, as the rust (iron oxide) can create a brittle layer that compromises its structural integrity. This degradation makes rusted iron more susceptible to breaking or crumbling under stress. While some areas may still retain strength, overall, rusted iron is considered less durable and more easily broken compared to its non-rusted counterpart.
Rust on iron is a hydrated iron oxide.
Rusted iron, or iron oxide, does not contain the same magnetic properties as pure iron. The presence of rust creates a barrier between the iron atoms and the magnetic field, reducing the overall magnetism. Additionally, the rust itself is not magnetic, further decreasing the attraction to a magnet.
Rusted Iron that rusted over thousands of millions of years!
it will be rusted because of the H2O and oxgen
This is not pure iron but a special steel.
If it is "rusted out" you do not repair it, You do replace it with XHCI
Iron and oxygen
It rusted away.
no it is a chemical change
Rust is not very strong.
