Magnesium Oxide Insulator is designed to electrically isolate and provide mechanical support to the thermoelements of thermocouples. With a melting point of 3098K, it boasts the highest melting point among oxides, ensuring excellent heat resistance. Known for its superior corrosion resistance in molten metal environments, magnesium oxide is a more versatile and reliable choice than aluminum oxide, making it ideal for a wide range of metal applications. This insulator guarantees long-lasting performance, even in extreme conditions, offering both electrical insulation and mechanical stability.
