The main features of high precision ceramic parts
1. High precision dimensions with tightening tolerance, it's easier to get a perfect fitting relationship
2. Wear & abrasion resistance: Alumina is an extremely hard technical ceramic with superb wear resistance
3. High-temperature ability: withstand up to 1650°C in oxidizing and reducing atmospheres
4. Chemical inertness, resistant most of the strong acid and alkali, and does not rust forever
5. Electrical insulation: The insulation breakdown is up to 18KV at least
6. Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel
7. Chemical corrosion resistance under high temperature, even if with strong acid or alkali
8. Protective atmospheres or high vacuum at high-temperature to eliminate contamination or impurity.
9. Low material cost in high-level applications than other technical ceramics

The description of high precision alumina ceramic parts
Alumina (Al2O3) 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 tighten tolerance, 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.
