Hello Pete,
I posed the question because I've written a small programme that calculates
the skin depth of 14 different metals. Chromium and stainless steel are two of
the metals in the programme. I found a value for chromium in the ARRL Handbook
of 1.8 times the resistance of copper. On further investigation I found other
values of around eight times the resistance of copper, hence by bulletin. Skin
depth varies with the resistivity and permeability of the metal in question.
The resistance of chromium in chromium plating is what I would like to know.
Interesting what you said about the thin films. I have a Russian book on metals
that says the properties of chromium, including conductivity, change
drastically at 37 Celsius.
Ok on the stainless steels Pete. There are many different types as you say.
Do you have any information on the resistivities of the types that may be
used for making antennas or used in some electronic application?
