Mine as well. Aluminum has higher thermal conductance than iron/steel, and as a the foil itself is much smaller than the skin depth of aluminum, the resistance is bumped up significantly. That being said, the skin depth in magnetic iron foil should be similar when you take into account the...

Hey everyone. This question revolves around induction/cap sealing - or just induction heating in general. Does anyone have an idea of why aluminum foil is used in induction sealing vs. using something that is magnetic, such as iron foil? My initial thought is simply aluminum foil being...

Which do you believe is the best choice for a low temperature RF heating susceptor, i.e. - greatest rise in temperature vs. field strength. I am aware that Graphite (expanded graphite foil) has excellent thermal conductance in plane and therefore makes for very even heating patterns over large...
