Which conductor should be used for high-temperature environments?

Tinned copper conductors are specifically suited for high-temperature environments due to their enhanced resistance to oxidation and corrosion. The tin coating provides a protective barrier that helps maintain conductivity even in elevated temperatures while preventing deterioration from factors like moisture and atmospheric exposure. This makes them particularly valuable in applications where conductors are exposed to excessive heat or oxidizing conditions.

In contrast, aluminum conductors can corrode more easily and have lower temperature ratings compared to copper offerings. Standard copper conductors, while effective in many applications, do not have the additional protective qualities that tinned copper provides. Nickel-plated conductors can withstand high temperatures but are often more expensive and not as common for general use where tinned options are sufficient and more readily available. Therefore, tinned copper is recommended for high-temperature scenarios due to its durability and reliability.
