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.

What element makes overhead sprinklers?
Overhead sprinklers are typically made of brass, stainless steel or plastic materials. These materials are used for their durability and resistance to corrosion, making them suitable for long-term use in sprinkler systems.
What kind of sprinklers do not need melting to set it off?
Sprinklers that do not need melting to activate are called "fusible link sprinklers." Instead of relying on heat to melt a fusible link, these sprinklers have a heat-sensitive element that responds to a certain temperature, causing the sprinkler to activate and release water.
What element is liquid metal used in the thermometers?
Mercury is the element commonly used in liquid-in-glass thermometers.
What is the element that is used in toothpaste and teflon?
Fluorine is the element used in toothpaste as fluoride, while Teflon is made of the element fluorine in combination with carbon to create a non-stick coating.

Should fusible link sprinklers be used in a deluge system?
No, sprinklers in a deluge system are "open"; no valve in the sprinkler, and an automatic valve turns on the water to all open sprinklers when a fire condition is detected.
What is the most commonly used brand of sprinkler?

How do you calculate predetermined overhead?
You take estimated overhead divided by the estimated level of production activity. It is used to assign overhead to production.
What do sprinklers in a factory remove from the fire triangle?
Sprinklers in a factory remove heat from the fire triangle.
Why do grocery stores have sprinklers?
Grocery stores have sprinklers only above the produce section because, when it is time to, the sprinklers automatically turn on according to how dry and products are. Hoped this helped! :)
What are pergola kits and how do I use one?
A pergola is a overhead structure used to make the outdoors more inviting, to extend livable space, to create a shady retreat, and serve as a major landscaping element.
When is the Predetermined overhead rate usually calculated?
The predetermined overhead rate used to apply overhead to finished jobs is determined before the period begins.
