What materials have a high specific heat capacity? Gray Granite- With a specific heat of almost three tenths that of water, gray granite has the highest specific heat of the materials by a significant margin. This means it has a large heat capacity, and requires a relatively large amount for heat energy to raise its temperature. Cast iron is a relatively poor heat conductor, one-third as good as Specific Heat Capacity. Gray cast iron is the Scroll down to the part that says specific heat. Latent Heat of Specific heat of Iron is 0.44 J/g K. Specific heat, or specific heat capacity, is a property related to internal energy that is very important in thermodynamics.

Does iron have a higher specific heat than water? The specific heat of cast iron (0.46 kJ/kg-K) is roughly half that of aluminum (0.96 kJ/kg-K), but the melting point is almost double (1200 C for cast iron and 600 C for aluminum), so . The only info I could find on this subject is from ASM HANDBOOK Volume 1: Heat of fusion for ferritic and pearlitic grades of ductile iron is about This article discusses the influence of microstructure and chemical composition on the physical properties of cast iron.

Generally, heat treatment methods applied to grey cast iron types are stress relief due to its non-uniform cooling of iron castings, and to increase machinability annealing is performed. 0.95. It is an intensive propertythe type, but not the amount, of the substance is all that matters. What is the specific heat of iron? As high chromium irons are quite brittle, the castings are heated slowly in a cold furnace to 650C to avoid thermal cracking (as these are bad conductors of heat).
