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.
성능 특성
내마모성: 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.
높은 내열성: 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.
높은 강도: 굴곡 강도는 300~400MPa로 기계적 특성이 뛰어나며 큰 하중과 응력에도 견딜 수 있습니다.
내식성: 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.
단열 속성: 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.
