    Simply stated, the basic problem in designing an electrical heating element for any given application is that of selecting a type and size of resistance wire, ribbon or strip which will operate satisfactorily at the desired temperature under specified environmental condition-and one which can also be coiled or otherwise formed into an element that will fit within the space provided for it in the device itself.

    While there is no substitute for experience in solving such a problem, the information presented in this Section will serve as a helpful guide in correlating the various factors involved for proper application of our Chromel® resistance alloys.
