Especially the thermal conductivity is of high interest for the metals that are stripped at Galvano-T. Copper behind silver is the metals that has the best conductivity. Only diamond can beat this. For a lot of cooling bodies this splendid heat conductivity accompanied by excellent firmness values is the reason why some of those structures can exist.
For galvanical stripped nickel similar things are important. As an alternative to high-grade steel for schabe heat exchangers nickel has a comparable firmness and tenacity and a far better heat conductivity. Many non-austenitic ferrous materials also have great coefficients but a far worse corrosion resistance.
Maximum thermal conductivity of different materials in W / (m · K)
The thermal conductivity of Diamond is 2300 W / (m * K). To illustrate the thermal conductivity of different materials in detail we excluded the Diamond and other materials. In the table below this chart those values are still included.
The following table shows the values of different materials, including the Diamond and values of materials excluded in the chart above.
