If you are talking about the little rod that melts causing the sprinkler to spray water, it is not an element. It is either a metal alloy or plastic that melts at a relatively low temperature. The older sprinklers all used metal alloy, but as the usual alloy contained lead as one of the metals that alloy has been phased out due to concern over toxicity. Where metal alloy is still used it has been reformulated without lead. But the preference now is to use plastic rods.
The image above shows a sprinkler with red colored plastic rod.
