These thermal greases have low electrical conductivity and their volume resistivities are 1.5⋅10 15, 1.8⋅10 11, and 9.9⋅10 9 Ω⋅cm for 860, 8616 and 8617 respectively. The thermal grease 860 is a silicone oil with a Zinc Oxide filler and 8616 and 8617 are synthetic oils with various fillers including Aluminum Oxide and Boron Nitride.
Stainless steel is considered stainless because it has at least 11% chromium by mass. Chromium is a relatively inert metal and does not rust or react as easily as plain carbon steel. This is what makes it an exceptional material for cooking. It is also fairly inexpensive, but does not have a very high thermal conductivity.
Commercial pans are sometimes made from aluminized steel which combines the conductive, reflective, and food adherence properties of aluminum, with the rigidity, mass, and strength of the inner steel core (in this process, the aluminum surface is typically 90% aluminum and 10% silicon, which is not quite the same as pure aluminum). Mass ...
Electrical conductivity of water samples is used as an indicator of how salt-free, ion-free, or impurity-free the sample is; the purer the water, the lower the conductivity (the higher the resistivity). Conductivity measurements in water are often reported as specific conductance, relative to the conductivity of pure water at 25 °C.
Aluminum's high thermal conductivity makes the temperature more uniform across the pan. Stainless frying pans with an aluminum base do not have the same temperature at their sides as an aluminum sided pan. Cast iron frying pans work well with induction cooking surfaces, although the material is not as good a thermal conductor as aluminum.
Some of the important characteristics of materials are : strength, durability, flexibility, weight, resistance to heat and corrosion, ability to cast, welded or hardened, machinability, electrical conductivity, etc. [3] In contemporary design, sustainability is a key consideration in material selection.

Aluminized steel can be made using a variety of processes, cladding, hot dipping, galvanic coating, metallizing, and calorizing, but the most effective process is hot dipping. The process of hot dipping starts by cleaning the steel, then placing the steel in a bath of Al-11%Si at a temperature of 988K and shaken, then pulled out and air dried. [5]
