Which material is a poor heat conductor?A. IronB. SilverC. WoodD. Copper International Annealed Copper Standard (IACS) pure =1.7×10 −8 Ω•m =58.82×10 6 Ω −1 •m −1. For main article see: Copper in heat exchangers. The TPRC recommended values are for well annealed 99.999% pure copper with residual electrical resistivity of ρ 0 =0.000851 μΩ⋅cm. TPRC Data Series volume 1 page 81. Copper in heat exchangers - Wikipedia List of thermal conductivities - Wikipedia Copper in heat exchangers - Wikipedia Induction cooking - Wikipedia Aluminium is the most prominently used heat sink material because of its lower cost. Copper heat sinks are a necessity when higher levels of thermal conductivity are needed. An alternative to all- copper or all-aluminium heat sinks is the joining of aluminium fins to a copper base. Copper heat sinks are die-cast and bound together in plates. Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is ...
