OEM Diamter 2cm ceramic tube 95%Alumina ceramic parts with good hardness

Product description

Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance, but relatively low strength and fracture toughness. Alumina ceramic is generally white but may also be pink or ivory. The color is derived from either the sintering additives or impurities in the raw materials.

99% Alumina ceramic is used to make high-temperature crucible, furnace tube and special wear-resistant materials, such as ceramic bearing, ceramic seal and water valve sheet, etc.
95% alumina ceramic is mainly used as corrosion-resistant and wear-resistant parts.Due to the addition of talc, the electrical properties and mechanical strength are improved, which can be sealed with molybdenum, niobium, tantalum and other metals, and some are used as electrical vacuum devices.

2. Feature:

1). High hardness and High density
2). Low thermal conductivity
3). Chemical inertness
4). Good Wear resistance
5). High fracture toughness
6). Good insulation performance
7). high temperature resistance

3. Advantages:

1). 95% alumina or steatite ceramic.heat compression molding,the alumina has been to improved insulation and mechanical strength.

2). The ceramics have no cracks,no burrs,no pinholes,no gaps,and no impurities, surface is smooth, dye absorption is passed.

3). Linear dimension tolerance ≤ ± 0.05mm, diameter tolerance ≤ ± 0.1mm, hole size distortion ≤ 0.05mm, circumference deformation size ≤ 0.1mm.

4).  Insulation Resistance ≥ 100MΩ (have been checked by megohm in DC500V).

5). Dielectric Strength: AC2000V/50HZ/1min no breakdown phenomenon.

6). Linear expansion coefficient is slight,and less than 7.0 × 10-6mm /°C, and good for thermal shock performance.

7). Sintering temperature is 1350 °C, the use of a temperature not lower than 1100 °C, good corrosion resistance.
