WebAs alloys have the desired property, they are used to design heating elements for different applications. Nichrome (80% Nickel, 20% Chromium) is the most common alloy used for making heating elements for electrical appliances. Because nichrome does not oxidize and burn easily at high temperatures It has higher resistivity. WebQ = considering the amount of heat which must be lost to produce solidification. = ρV [L + c (θ p – θ 1 )] where, ρ = density of metal, V = volume of metal. L = latent heat of fusion of metal. θ p = pouring temperature. c = specific heat of metal. This time for solidification for a plate is proportional to (V/A) 2.
