Alumina ceramic tube sleeves, with their excellent physical and chemical properties, are widely used as protective or barrier layers in several industries.
Designed with a variety of structural forms, these tube sleeves are intended to suit different application environments and functional requirements. Key features include high density, excellent abrasion and temperature resistance, and superior electrical insulation properties.
Aluminium oxide ceramics have a density of up to 3.85 g/cm³, ensuring stability and durability under high loads. At the same time, the Vickers hardness of 15.7 GPa enables it to maintain good mechanical properties in extreme environments.
Aluminium ceramic tube sleeves first and foremost play an important role in the electronics industry. Due to its non-conductive nature, it can be used as a protective layer for wires or sensitive electronic components against electrical interference and environmental factors. In addition, its excellent resistance to thermal shock and its ability to withstand temperature variations of up to 200°C make it outstanding in high-temperature operating environments, e.g. up to a maximum operating temperature of 1,650°C.
Shenzhen Haorui Industrial Technology Co., Ltd was established in June 2006, and it has specialized in the research & development, fabrication and sales of non-standard industrial ceramics, hard alloy (such as tungsten steels), metals and non-metal precision machinery parts for 18 years.
The company has a strong technical level in the processing and manufacturing of industrial ceramics (i.e. zirconia, alumina, silicon nitride, silicon carbide, aluminum nitride, etc.), hard alloys (such as tungsten steels,) non-standard precision parts. The company holds many leading technologies in this field. Moreover, the company has a group of professional technicians with strong technical development abilities and over 10 years working experiences.Most importantly, the company also has a complete production process and quality management system, as well as a complete set of precisely machining equipments and inspection facilities.
