Very sorry for the mistake.

Yes, the flat tuber are made also of copper but to 85%, it is a league, it is not gotten to work the pure copper in the format of flat tubes, he doesn't support that when it is modeled, that and been worth for any radiator with flat copper tubes, the only difference is that the manufacturers don't mention that, that was me informed for the it manufactures that produces the core for me.
And yes all flat tubes in every rad (BIX, BM..) are in brass because copper is unworkable with a such small thickness (0.05mm to 0.1mm) but it's not a problem for thermal exchange with this thickness
They consider leagues above 80% in an only material as pure, to the they think to be unnecessary you mention it
The own dteck announced your radiators with being 100% cooper, today her no longer itmentions more that, the chanbers are of brass and the flats they are mixed
My chanbers are 100% copper fastened with it welds to 57% silver, as well as the flats, they chambers are underneath of the cases in lateral inox
