High-temperature terminals are typically made from which of the following materials?

High-temperature terminals are specifically designed to withstand elevated temperatures and harsh environments often found in commercial kitchen equipment and other industrial settings. The materials chosen for these terminals play a crucial role in their performance and longevity.

Nickel, nickel-tinned steel, and plain steel are selected for their excellent heat resistance and mechanical strength. Nickel plating helps to prevent corrosion, while steel provides structural integrity, ensuring that the terminals can maintain a reliable connection even under extreme conditions. This makes them particularly suited for applications where high temperature and oxidation are concerns.

In contrast, copper and aluminum, mentioned in some other choices, have good conductivity but may not withstand high temperatures as effectively without degrading. Plastic and rubber composites are not suitable for high-heat applications due to their lower melting points, while gold and silver alloys, while excellent conductors, are typically not used in high-temperature applications due to cost and material properties that do not suit the rigorous demands of such environments.
