(hereinafter referred to as "Yunxing Industrial Ceramics") has, with more than 20 years of intensive development, become a benchmark supplier of high-quality alumina ceramic tubes in the industry by virtue of high-purity products, exquisite craftsmanship and comprehensive services, responding to market expectations with strength.
As a seasoned industrial ceramics enterprise founded in 2000, Yunxing Industrial Ceramics has deeply rooted in the alumina ceramics field for more than 20 years. Adhering to the core positioning of "only producing high-purity alumina ceramics", the company specializes in the R&D, production and sales of high-quality alumina ceramic tubes.
Covering an area of 16,723 square meters, Yunxing has built a full-process independent production system from raw material purification to finished product inspection. Its products are not only widely used in various industrial fields across China, but also exported to more than 30 countries and regions around the world, gaining wide recognition from customers both at home and abroad.
It has become the preferred partner for many university laboratories, large machinery enterprises and mining enterprises.
High-quality products start with strict raw material control and technological breakthroughs. Unlike some enterprises in the industry that use medium‑low purity raw materials to reduce costs, Yunxing Industrial Ceramics insists on selecting high‑purity alumina raw materials. The alumina content of our alumina ceramic tubes can reach 99.3%–99.5%, far exceeding the industry average.
High‑purity raw materials endow the products with superior performance: after being sintered and cooled in a high‑temperature furnace at 1800°C, the products are not prone to cracking or deformation under high temperatures. The bulk density is above 3.92 g/cm³, with a smooth and dense surface that is resistant to chemical corrosion. Meanwhile, they feature excellent hardness, wear resistance and thermal stability, greatly prolonging the service life compared with ordinary products.
Exquisite production techniques and strict quality control are the core guarantees for the product quality of Yunxing Industrial Ceramics. The company is equipped with advanced production and testing equipment, and has built standardized production workshops, realizing the standardized production of the whole process from raw material proportioning, forming, sintering to precision machining. It can flexibly produce alumina ceramic tubes of various specifications with outer diameters of 5–120 mm, outer diameters of 0.8–12 mm, and lengths up to 1800 mm. Customized production is also supported to meet the personalized needs of different customers.
In terms of quality control, the company has established a full-process inspection system, ranging from component testing of incoming raw materials, random inspection of semi-finished products during production, to multiple performance tests of finished products before delivery, including hardness, density, high-temperature resistance, and corrosion resistance. Every procedure is strictly controlled to ensure that the factory product qualification rate reaches the industry-leading level. The excellent performance of its products has been fully verified by the market, and they are widely used in high-temperature furnace insulation, thermocouple protection, high-temperature insulation and other scenarios, demonstrating strong practicality and reliability.
