I don't know the melting point of the USP beewax. It was bought by the 1 pound brick and pieces melted as needed in a pot. I suspect that it is only a sterile and filtered version.

As a radio hobbyist it has taken 40 years to use up one brick. None of my coils ever melted or moved. Keep in mind that the fine wire that is waxed will fuse (at the bend points) before it gets warm enough to melt. If you are worried about the wax melting by tube heat, relax. Heat generating rectifiers and audio output tubes are usually located distant from RF/IF coils.
