Description

Structural Machining Zirconia Ceramic Material Components IATF16949

1. Description:

Advanced ceramic materials are produced using highly refined and purified powders that, in many cases, are synthetically produced using high temperatures or chemical reactions. When formed and sintered properly these powders result in product that are very strong, very high in abrasion resistance, can withstand high use temperatures, very good chemical resistance, and very stable.

Advanced ceramics such as alumina, aluminum nitride, zirconia, silicon carbide, silicon nitride and titania-based materials, each with their own specific characteristics, offer a high-performance, economic alternative to conventional materials such as glass, metals and plastics.

2. Feature Advantages:

1) High density.

2) High fracture toughness .

3) High hardness High Mechanical Strength.

4) Low thermal conductivity Excellent insulation .

5) Good Wear resistance.

6) Resistant to Corrosion and Chemical Attack.

7) Extreme Temperature Stability.

8) Outstanding Electrical and Electronic Properties.
