▪ Alumina multi bores tube made by 99.3%-99.7% high purity alumina. ▪ Alumina ceramic porous tube max working temperature is 1800℃. ▪ The quality can pass the SGS and DIN43724/DIN43725/DIN40680. ▪ Both end open with good verticality. ▪ Can produce the 2-10 holes, max length 1850 mm.

1. High Temperature Resistance: Alumina ceramic porous tubes can withstand extreme temperatures, making them suitable for environments where thermal stability is crucial. 2. Chemical Inertness: They are chemically inert, meaning they do not react with most chemicals. This property is essential in applications involving corrosive substances or harsh environments. 3. Mechanical Strength: Despite their porosity, alumina ceramic porous tubes maintain excellent mechanical strength, ensuring durability and reliability in demanding conditions.
