as compared to
"Yellow Brass (Copper Alloy Nos. 268 and 270) — An alloy containing nominally 65% copper and 35% zinc and generally available in flat products, wire and rod."
thermal cnoductivity 67 Btu/(h.ft².°F/ft) ~ 116 W/(m².K/m)

the thermal conductivity of Red Brass is 37% better than Yellow Brass (and both are FAR below 'pure' copper)
but since the air side convection is the limiting factor, so what ?

rads are ALL about airflow
yes, these data are right, but it excuses, I didn't understand what you ask me

you repeat being clearer?
