Hi mr_intensity,
Well, I don't have an expert on tap for this forum, so I'll have to take a shot at it myself.
I think the first thing to note is that there is no magic bullet (or material) for this situation - said another way, I don't think it's sufficient to simply try to block or reduce the flow of heat through the material. At some point, the energy _will_ transfer through it, no matter how slowly. I think you will need to incorporate some kind of idea to transfer the heat away from the area.
Also, it kind of depends on what you mean by 'easy'
. After consulting with and slicing the data found on this page:
https://www.engineeringtoolbox.com/therm...d_858.html
It turns out that a few different types of stainless steel might be good options. From the table where 6.3 (W/m K) ... (uhm, watts per meter per degree kelvin? I have no clue ) is the lowest listed, here are some of the steel values:
11.6 Steel - Nickel Chrome, 40% Ni, 15% Ni
14.3 Steel - Stainless, Type 347
14.4 Steel - Stainless, Type 304
15.1 Steel - Chrome Nickel, 20% Cr, 15% Ni
17 Steel - Nickel Chrome, 80% Ni, 15% Ni
19 Steel - Chrome Nickel, 15% Cr, 10% Ni
19 Steel - Nickel, 20% Ni
19 Steel - Nickel, 60% Ni
I think several of those are commonly available. Now you get to decide if they're 'easy' to machine.
I'm wondering if there is a sane way to incorporate a means to move the heat away from the plate - perhaps combining a conductive material to transmit heat laterally out to some 'fins' to dissipate the energy, with a stainless steel base plate to act as a block.
So - if there are any experts out there, don't just laugh at me, jump in and offer some advice.
