Product Introduction

High Electrical Insulation 95% Alumina Thread Ceramic Tube

95% aluminium oxide ceramic threaded pipes are valued for their hardness, wear resistance, and high-temperature stability. They feature a low thermal expansion coefficient, ensuring dimensional stability across temperature changes. These pipes are strong, non-porous, and excellent for creating vacuum-tight seals, suitable for high-temperature brazing. Their resistance to abrasion and chemicals makes them ideal for chemical processing and other tough environments. Economical and reliable, they're widely used in electronics, chemical, and aerospace industries.

Main Features:

1. High hardness

2. High heat resistance

3. Good wear resistance

4. High electrical resistivity

5. High corrosion resistance

Production process

1. Grind and crush the raw materials to be slurry or powder

2. se-different method to making the slurry or powder into semi-finished products

3. Put the semi-finished products into the kiln for dewaxing and sintering;

4. After forming and sintering, Ceramic Sleeves products can also be processed by subsequent CNC precision machining according to the drawing requirements. Then Q/C test.

5. Finally package Ceramic Sleeves by bubble paper or cartons and place it on tray for delivery
