Thermal conductivity refers to the measure of the ability of a material to allow the flow of heat from its warmer surface to its colder surface. The thermal conductivity of cast iron is 80 Wm-1K-1.
Copper has a high thermal conductivity, not low. This is a good generalization of any metal, although they vary in conductivity.
The cabling to Earth is done for electrical conductivity, not for thermal conductivity. The general idea is to get rid of excess charges.

To crack cast iron, temperatures generally need to exceed 1,200°F (about 650°C). At this high temperature, the material becomes more brittle and susceptible to thermal stress. Rapid cooling or thermal shock can also induce cracking, even at lower temperatures, if the cast iron has been heated unevenly. It's essential to handle cast iron carefully during heating and cooling to prevent such damage.
The thermal conductivity of mild steel typically ranges from about 45 to 60 W/(m·K) in SI units. This property indicates how well the material can conduct heat, with higher values signifying better conductivity. Various factors, such as alloy composition and temperature, can affect the exact value within this range.

thermal conductivity of iron ore
The thermal conductivity of pure iron is approximately 80 W/mK at room temperature.
Yes, ductile iron is conductive. Its electrical conductivity is similar to that of gray cast iron due to the presence of graphite in its microstructure. This makes it a good choice for applications where electrical conductivity is required.
Cast iron is a good conductor of heat because it has high thermal conductivity. This means it can distribute heat evenly throughout the skillet. However, iron itself is not a good conductor of electricity, so a cast iron skillet would be considered an insulator in terms of electrical conductivity.
The thermal conductivity of galvanized iron typically ranges from 52-73 W/(m·K). This means that galvanized iron is a moderately good conductor of heat, making it suitable for applications where heat transfer is important.
Iron and aluminum thermal conductivity, fire burn immediately hot, if the handle of the pot is a stronger thermal conductivity something hand contact will be scalded, not strong thermal conductivity of wood and plastic, so use them. The thermal conductivity of aluminum is stronger than iron, but do not recommend cooking with aluminum pots, wok cooking can supplement some lack of iron, and aluminum can not. Aluminum pan and cook over time will iron deficiency.
Metals like copper, aluminum, and iron have high thermal conductivity. Other materials with good thermal conductivity include diamond, graphite, and ceramics like silicon carbide. In general, materials that are good conductors of electricity also tend to have high thermal conductivity.
It's very unreliable for electrical conductivity, hence why it's not used and there's nothing on google for 'electrical conductivity of cast iron'
The thermal conductivity of rusted iron decreases because rust, which is mainly composed of iron oxides, is a poor conductor of heat compared to pure iron. The presence of the non-conductive iron oxide layer disrupts the flow of heat through the material, resulting in a lower thermal conductivity. Additionally, the formation of rust can create interfaces and boundaries within the material that further impede the transfer of heat.
I don't have a numeric answer for you, however, I do know that sheet aluminum has better thermal conductivity than cast. It has to do with the way that cast aluminum cools.
Air is the best insulator among silver, copper, iron, and air. This is because air has a lower thermal conductivity compared to the metals silver, copper, and iron. Insulators with low thermal conductivity are better at reducing heat transfer.
