Prime features of alumina ceramic parts :

1. Wear & abrasion resistance: Alumina is extreme hard technical ceramic with superb wear resistance

2. High-temperature ability: withstand up to 1650°C in oxidizing and reducing atmospheres

3. Chemical inertness, resistant most of the strong acid and alkali, and does not rust forever

4. Electrical insulation: The insulation breakdown is up to 18KV at least

5. Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel

6. Chemical corrosion resistance under high temperature, even if with strong acid or alkali

7. Protective atmospheres or high vacuum at high-temperature to eliminate contamination or impurity.

8. Low material cost in high-level applications than other technical ceramics

Description of high precision alumina ceramic parts:

Aluminum oxide (Alumina) is a hard-wearing technical ceramic material frequently used in a broad range variety of industries applications. After firing and sintering, the alumina ceramic parts can only be precisely machined using diamond-grinding methods. It's charactered by high hardness and wear resistance, low erosion levels, high-temperature resistance, corrosion resistance, and chemical stability. Furthermore, it can be highly polished making it a mirror surface to reduce friction at the fitting, working status.
We offer a selection of purities ranging from 95 – 99.8%. Our factory has access to many different types of shaping methods, including dry pressing, hot pressing, ceramic injection molding, ISO pressing, tape casting, and extruded.

Our facility is capable of machining a variety of complicated ceramic parts with a very high accuracy dimension through fine grinding, lapping, CNC machining, laser cutting and so on.

The application of alumina ceramic parts:

Due to high purity alumina versatile characteristics, high precision alumina ceramic parts are widely used as ceramic mechanical seals, ceramic semiconductor parts, ceramic machine components, electrical ceramic insulators, ceramic waveguides, ceramic measuring components, fiber optical application.

Packaging proposal and transportation solutions

1. We will keep the ceramic parts inside the inner package to be fixed without moving, then it will prevent them from collision each other,

to avoid any cause any chippings during transportation.

2. In addition, the inside of the outer carton will be filled with sufficient protective kinds of stuff.
