Ningbo Victor Import And Export Co., Ltd has been manufacturing ceramic components for more than 10 years. We aim to provide customers the best quality products with the most competitive prices, thanks to our skilled workers, we can always save the production cost without reducing quality of products.

The application of alumina ceramic:

Alumina ceramic as one of the most well-known ceramic material, as its various levels of purity(85% Al2O3, 90% Al2O3, 95% Al2O3, 96% Al2O3, 99% Al2O3), and excellent mechanical, electrical, thermal and biochemical performances, widely used in high electrical insulation, high mechanical strength, high temperature resistance, high wear and chemical resistance.

The advantages of alumina ceramic:

- Electrical insulation

- Mechanical strength

- Low density

- Tracking resistance

- Resistance to high temperatures

- Resistance to thermal shock

- Wear resistance and hardness

- Resistance to climate and ageing

- Environmentally compatible disposal

- Chemical resistance

- Food safe

The manufacturing process of alumina ceramic:

Ningbo Victor Import And Export Co can manufacture alumina ceramic via four different process, include dry pressing, injection moulding, isostatic pressing and extruding. We will manufacture the alumina parts as per customer’s process requirement, or recommend the most cost-effective process.
