What statement is true regarding the melting point of a eutectic alloy?

Eutectic alloys possess a unique characteristic whereby their melting point is fixed and remains constant when they undergo repeated melting and solidification cycles. This stability arises because a eutectic alloy has a specific composition of its constituent metals that gives it a defined melting point, lower than that of the individual metals in the mixture.

Unlike non-eutectic alloys, which can show variable melting points due to changes in composition with repeated processing, eutectic alloys will always melt at their defined temperature point. This property is essential for various applications in metallurgy and materials science, as it ensures predictable behavior during casting and processing.

In contrast to the other options, the melting point of a eutectic alloy does not vary based on the individual metals used or increase with repeated usage; it also isn't influenced by the processes of melting and resetting.
