A peltier plate is an electrical component used in a wide range of applications to cool or heat electronic devices. It works by transferring heat from one side of the plate to another through conduction, which occurs when metal atoms vibrate at different frequencies. The metals used for a peltier plate can vary depending on the specific application and the desired performance characteristics.

One type of metal commonly used in peltier plates is copper. Copper has a high thermal conductivity and excellent resistance to corrosion, making it an ideal choice for use in high-temperature applications. Copper also conducts electricity well and has a low melting point, which means that it can be easily melted and reheated without losing its thermal properties.
Another common metal used in peltier plates is aluminum. Aluminum has a low thermal conductivity and a high electrical conductivity, making it a good choice for use in applications where both temperature control and electrical conductivity need to be maintained. Additionally, aluminum is lightweight and durable, which makes it suitable for use in high-temperature applications such as in the automotive industry.
Plastic materials such as polypropylene and polyethylene are also commonly used in peltier plates due to their low cost and durability. These materials have a high thermal conductivity and good insulation properties, making them ideal for use in applications where thermal management is critical.
In addition to copper and aluminum, other metals such as nickel, cobalt, and lead are commonly used in peltier plates due to their high thermal conductivity and good resistance to corrosion. Nickel has a high thermal conductivity and good electrical conductivity, while cobalt has a low melting point and is resistant to corrosion. Lead has a high melting point and is resistant to corrosion, but it has a lower thermal conductivity than other metals.

Overall, the choice of metal for a peltier plate depends on various factors such as the desired performance characteristics, the cost, and the intended application. However, in general, copper and aluminum are two of the most commonly used metals for peltier plates due to their high thermal conductivity and excellent resistance to corrosion. Other metals such as plastic and nickel may also be used depending on the specific application requirements.
