The water-bearing parts are made of a really fine stainless tube, with an inside structure, which allows an optimal thermal transfer to the outside aluminum-fins. Everyone knows about the heat conductance of copper and we all know, that stainless steel is worse than copper. But, in this case we only need a thermal breakthrough to the aluminum and that’s mostly dependent on physical inertia. The wall-thickness of the stainless tube is only 0,2mm. So, the heat of the coolant is moving right through to the alu-fins…
This is true for Thermalfins rads too, which again indicates similarities between newcomer rads and Admiral. But this also shows that Feser could have placed orders at LottersMettal to produce Admiral. Here is how Tom comments the situation:

Many of you might be familiar with the history of these radiators, so I'll skip this "dark chapter of a cooperation".
It's true that the radiators look a lot alike as they are part of the same "family".
The entire production is designed for high quality...starting at the used materials (I know...stainless steel), over the way surface treatment, to the service. Why stainless steel out of all the possibilities?
When taking a look at the prices of copper, one can see that they are skyrocketing. Stainless steel can't transfer heat as good as copper, but, and this is the most important part, if I cover a 0.2mm thick pipe out of stainless steel with an aluminum pipe, the material of the inner pipe gets less and less important... (Did anyone ever touch a knife out of stainless steel, that just came out of the dishwasher? It's damn hot!)...a thermal breakthrough occurs, the thermal conductivity of the aluminum is all that counts, so everything works out just fine. So much for the stainless steel issue.
Also, there's no soldering involved in the production. Everything is welded together by lasers, resulting in no deformation at all. It also doesn't require any additives, so the radiators are fully RoHS-compilant.
I hope I was able to explain a few things...
