Pure and eutectic metals usually have narrow solidification ranges. The alloy that forms has a low eutectic melting temperature. Reactor salts are usually close to eutectic mixtures to reduce their melting point. In either case, magmas will evolve to the eutectic for crystallization upon cooling. The issue was that the lead/bismuth eutectic solution solidifies at . Mechanical linecasting equipment use alloys that are close to eutectic. Lead, lead-bismuth eutectic, and other metals have also been proposed and occasionally used. The temperature of the eutectic bonding procedure is dependent on the used material. Wetting is a property of the alloy when within its specific eutectic temperature range. The third stable eutectic has 18.4% (mass) of NaOH. A eutectoid (eutectic-like) alloy is similar in behavior to a eutectic alloy. Conversely, when a well-mixed, eutectic alloy melts, it does so at a single, sharp temperature. This leads to a poor adhesion of the eutectic bond. The eutectic temperature of this mixture is . Such a mixture can be either a solid solution, eutectic or peritectic, among others.
