Ask a Metallurgist Wrought Iron vs Cast Iron Metal
Cast iron can refer to a range of iron alloys but it is most commonly associated with gray iron. Despite having the name iron it isn t pure elemental iron (Fe on the periodic table)—it s actually an alloy containing 2–4 percent carbon plus small amounts of silicon and manganese. Jun 13 2020 · The strength and hardness of non-ferrous alloys are generally higher than pure metals and the resistance is large and the temperature coefficient of resistance is small.
