High Polished Outer Diameter Wearable 99% Alumina Ceramic Plunger Bar Rod

Aluminum oxide ceramic protective tube is a high-performance ceramic material mainly composed of aluminum oxide (Al2O3). This material is widely used in industrial fields due to its excellent physical and chemical properties, especially in high temperature, high pressure, and corrosive environments.

Our company provides alumina ceramic products, electron gun ceramic pads, ion source grid ceramics, coating machine ceramics customization, etc. 

Main Features:

1. High hardness

2. High heat resistance

3. Good wear resistance

4. High electrical resistivity

5. High corrosion resistance

Performance:

1. The strong acid and alkali resistance of zirconia ceramic shall be better than other materials.

2. Zirconia ceramics are not easy to wear, with strong durability. The hardness is close to the natural diamond and light than metals, also has the gem properties such as never wear and non - discoloring.

3. Can maintain the mechanical strength under high temperature, can be used in the condition with high temperature.

4. Good surface finish quality, could get more glossy smooth surface. Small coefficient of wear, with quite good self - lubricating function, non - magnetic, electric insulation, static - free, anti interference and radiation.

Technical Parameters

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
