Alumina ceramic sandblasting nozzle for argon arc welding (TIG) is a kind of high performance ceramic nozzle, which is mainly made of high quality alumina material.
Эксплуатационные характеристики
Износостойкость: Alumina ceramics have extremely high wear resistance, with a hardness of 9 Mohs hardness, which can resist wear and corrosion, ensuring that they can still maintain good spray performance during long-term use.
Устойчивость к высоким температурам: Alumina ceramic nozzles can maintain stable performance in high temperature environments, are not easily deformed or damaged, and are suitable for high-temperature welding processes.
Высокая прочность: Его прочность на изгиб составляет от 300 до 400 МПа, он демонстрирует отличные механические свойства и способен выдерживать большие нагрузки и напряжения.
Устойчивость к коррозии: Alumina ceramics have good corrosion resistance and can resist the corrosion of acids, alkalis and other chemicals, making them suitable for use in corrosive environments.
Изоляционные свойства: Alumina ceramic nozzles can maintain stable insulation properties under high pressure and high temperature environments, making it difficult to conduct electricity, ensuring the safety and stability of the welding process.
