SOLDER
BY ELANA WOOSLEY AND ISAAC MILLER
SOLDER IS STRONG AND DURABLE WHEN SOLID. Here, solder is used in a clock.
-Solder is strong and durable when solid.
-Because it has a low melting point, it is easily melted to a certain shape and sets quickly.
-Because it has a low melting point, it is easily melted to a certain shape and sets quickly.
It is mainly 60/40 Sn-Pb and is a substitutional alloy. Solder can be used in a basket.
- Solder IS also A SUBSTITUTIONAL ALLOY
- Solder was used in this cage
It was used in ancient Egypt around 2000 B.C. In this picture, solder is used in a coffee mug.
It has a low melting point which lets it melt and set quickly. This is solder coil.
Tin/lead solder is highly toxic, and the government is trying to remove lead based solder because of this. Solder can be used in light bulbs.

WHY IS SOLDER USEFUL?
- Since solder has such a low melting point, it is easy to use to construct simple and widespread objects. E.G. Lightbulbs and circuit boards.
- Also, people who like crafting with metal can easily weld solder with a soldering iron. (That's why it's called a soldering iron)
A FEW INTERESTING FACTS ABOUT SOLDER:
- There is soft soldering and hard soldering. It is categorized by the melting point.
- Soft soldering is solder work done with solder that can be melted below 400 degrees Celsius.
- Hard soldering typically involves a solder with a percentage of up to 40% silver and melts at or above 450 degrees Celsius.
