The sintering temperature of alumina ceramic tubes is usually high, because the melting point of alumina is up to 2050 ℃. Therefore, the production of alumina ceramic tubes requires the use of high-temperature heaters or high-quality fuels and advanced refractory materials as kilns and furnaces, which to some extent limits its production and wide application. What are its advantages?

Premium Quality for European and American Customers: Recognizing the preferences of our esteemed European and American customers, we have meticulously crafted our alumina ceramic tube to meet the highest quality standards. It undergoes rigorous manufacturing processes, ensuring consistent performance and durability.

National Day holiday notice: 10.1 to 10.7. closed 10.8 on work Orders are normally accepted the holidays. Production starts after the holidays.

First many appreciate for the guidance provided by the customer of a century-old Japanese chemical company we cooperated with on the important data of our product performance. Through in-depth communication between our technical personnel, we found that there were the errors in the expression of the leakage rate in the performance index and changed it in time.

Alumina ceramic tubes, with their unique advantages such as high temperature resistance, strong insulation and high cleanliness, have become an indispensable core supporting component in semiconductor production lines.

Amid the transformation of industrial manufacturing toward high-end and green development, the operational stability of equipment under high-temperature, high-pressure and strong corrosive working conditions has become the key for enterprises to cut costs and boost efficiency.

2‑hole alumina ceramic tubes are manufactured from high‑purity alumina (99.3%–99.7%) as the core raw material through precision forming and high‑temperature sintering processes. Featuring open ends and excellent verticality, they can withstand an extreme temperature of up to 1800°C and meet international standards including SGS and DIN series.

As industrial manufacturing transforms toward high-end and precision development, alumina ceramic tubes have become key basic components in chemical engineering, metallurgy, electronics, new energy and other fields, thanks to their core advantages such as high temperature resistance, corrosion resistance, high hardness and excellent electrical insulation.

Outstanding hardness and excellent wear resistance are among the most competitive properties of alumina ceramics. According to tests by the Shanghai Institute of Ceramics, Chinese Academy of Sciences, its Rockwell hardness can reach HRA 80–90, and its Mohs hardness is as high as grade 9, second only to diamond and silicon carbide, far superior to ordinary wear-resistant steel and stainless steel.

Operating Temperature: The wear amount of alumina ceramics is largely dependent on the operating temperature. Alumina ceramics exhibit excellent performance at high temperatures, but prolonged exposure to extreme heat may gradually degrade the material. Adhering to recommended temperature limits helps maximize the lifespan of the product.
