WebThe thermal conductivity of cartridge brass – UNS C26000 is 120 W/(m. K). The heat transfer characteristics of solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It measures a substance’s ability to transfer heat through a material by conduction. WebFor electrical conductivity the Siemens per meter is used, symbolized by S/m. Conductivity is the inverse of resistivity. If we represent conductivity by σ(greek sigma) and resistivity by ρ(greek rho) their relation is given by: σ = 1 / ρ. The nanoOhm-meter nΩ.m (billionths of ohm-meter) is costumarily used to express resistivity in metals.
