Aluminum nitride (AlN), as an important III-V semiconductor material, has attracted great attention because of its high theoretical thermal conductivity (320 W m −1 K −1), high electrical resistance (>10 14 Ω cm), low dielectric constant (8.8), and low thermal expansion coefficient (4 × 10 −6 K −1) , which makes it an ideal filler for the preparation of TIMs. Heat Transfer Table of Content Properties of Metals - Thermal Conductivity, Density, Specific Heat . thermal conductivity of aluminum 6061 . To accurately characterize the geometric structure of closed‐cell aluminum foam, a three‐dimensional stochastic sphere model with adjustable porosity and pore size was established, and its thermal conductivity was studied by numerical simulation. Typically they are malleable and ductile, deforming under stress without cleaving. Effect on Thermal Conductivity: The chemical phase of the material: When the phase of a material changes, an abrupt change in its heat conductivity may arise.
