It is brittle, so no good under tension. It's better under compression.
Because aluminum is less dense so airplanes are able to fly without falling from the sky because it don't weigh them down as much and cast iron is more dense so it works against your muscles so therefor they become bigger.
Corrosion is not useful for any metal; an exception is electrocorrosion processing.
A cast iron railing is a metal railing.
iron is mostly converted because it is a soft metal and it is not that useful
we can use it to make forks :D
processing iron ore into metal for construction
Iron ore was traditionally used to make metal poles. These metal poles would be used as support beams in buildings for example.
because it is a hard metal that can only be moved by heat or fire.
white iron is metal
Yes, cast iron can be detected with a metal detector, as it is a ferrous metal containing iron. Most metal detectors are capable of detecting ferrous metals, although the sensitivity may vary depending on the detector's settings and the size of the cast iron object. However, smaller or deeper items might be harder to detect compared to larger objects.
because the cast iron is a ferrous metal
The metal free weights are made from cast iron.
