WebOverview of Heavy Metal Tungsten Alloy (ASTM B 777) Heavy metal alloys are pseudo-alloys of tungsten with a nickel-iron or nickel-copper matrix. They are produced by powder metal and sintering processes. Tungsten Heavy Alloys has a high density of 17-19 g/cm³. Comparable densities are only reached by gold or platinum. WebIt measures the rate of transfer of heat of a material from the hot side to the cold side. It has the SI unit of m²/s. Thermal diffusivity is usually denoted α but a , κ , K , and D are also used. The formula is: α = k / ( ρ c p ) where k is thermal conductivity (W/ (m·K)) ρ is density (kg/m³) c p is specific heat capacity (J/ (kg·K))
