Referring to your E.6/HP.28.6.34., the reason for our stressing the aluminium tube in preference to the steel tube e was from the point of view of the heat being conducted away along the length of the tube from the intensely heated portion in the centre, due to fact that the heat conductivity of aluminium is considerably better than the steel.
