Aluminum oxide ceramic threaded joint components

Aluminum oxide ceramic threaded joint is a tubular or rod-shaped connecting element made of high-purity (usually 95%, 99%, or 99.5% or more) aluminum oxide (Al ₂ O3) ceramic material and precision machined with internal and/or external thread structure.
This product perfectly combines the excellent performance of advanced ceramics and the versatility of threaded joints, aiming to replace harsh working environments that traditional materials such as metal and plastic are unable to handle. The manufacturing process usually includes isostatic pressing, high-temperature sintering, and ultra precision diamond grinding, ensuring that the product has extremely high dimensional accuracy, geometric consistency, and excellent surface smoothness, which can meet strict sealing and assembly requirements.

Core features:
Excellent corrosion resistance: able to withstand the corrosion of most strong acids (such as hydrochloric acid, sulfuric acid, nitric acid), strong alkalis, organic solvents, and various corrosive gases, fundamentally solving the problems of metal joints being prone to rusting, contaminated media caused by corrosion, and shortened service life.
Excellent wear resistance: With extremely high hardness (second only to diamond and silicon carbide), the Mohs hardness can reach level 9, effectively resisting the erosion and wear of materials such as powders, particles, and slurries. Its service life far exceeds that of metal joints, solving the problems of leakage and frequent replacement caused by wear.
Excellent high-temperature stability: It can maintain shape and performance stability for a long time in a high-temperature environment of 1600 ° C, with a small coefficient of thermal expansion, and will not soften or deform like plastics, nor will it undergo high-temperature oxidation like some metals.
Extremely high electrical insulation: With high resistivity and low dielectric loss, it is an ideal insulation connector for high temperature and high frequency environments, effectively preventing electrochemical corrosion and current leakage problems.
Biological inertness: non-toxic, odorless, does not adsorb bacteria, has good biocompatibility, and is very suitable for food, pharmaceutical, and biomedical applications, avoiding the problem of material contamination of media.
Low friction coefficient: Smooth surface, low friction resistance, especially suitable for conveying scenarios with strict requirements for material adhesion.
