Did some research today:
-Alloy has a heat transfer capability of 237 W/(mK) and an average heat capacity of 0,9kJ/kgK)
-compare that with copper:
heat transfer capability of 401 W/(mK)and an average heat capacity of 0,38kJ/kgK)
so the transfer capability is nearly twice that high than alloy and heat capacity is less than half.
In real world conditions that is an magnificent advantage. Heat is transfered much quicker and more effective than alloy.
The original brass copper radiatoris 39mm thick, and is a 27 line, including the upper and lower frame line 2 row radiator with 5 fins per 10 millimeter.
Now lets compare that with alloy radiators!
Please posts the dimensions and the make of your alloy radiator as a comparison!
