99% Alumina Ceramic Tube Ceramic Protective Sleeve Alumina Ceramic Cylinder

Alumina is a very hard ceramic that is excellent at resisting abrasion and is ideal for wear-resistant inserts or products. It is commonly used as a high temperature electrical insulator, particularly the higher purity grades which offer better resistivity. It also offers good resistance to strong acids and alkalis at elevated temperatures, which makes it ideal for applications where resistance to corrosive substances is required.

Manufacturing:

• Excellent electrical insulation properties
• High hardness and mechanical strength
• Wear and abrasion resistant
• High thermal conductivity and thermal shock resistance
• Low density
• Resistant to strong acid and alkali attack at high temperatures
• Transparent to microwave radio frequencies
• High compressive and dielectric strength
• Very specific thermal conductive and thermal expansion rates

FAQ:

1. Are you a factory?

Yes, we're a factory producing industrial ceramics professinally. Our main products are alumina ceramics, zirconia ceramics and sic ceramics.

2. What's the size of it?

Products are always customized according to drawings or samples. Diameter and height within 500mm are available.

3. What's the price for it?

It depends. Prices are caculated by the drawing size and structure.

4. What's the production process?

Our products are made mainly in cold isostatic pressing, dry pressing and hot press moulding technique. Hot press moulding technique, which was used to shape small and medium size and complicated structure ceramic, is a favorable method.

5. How about the delivery?

Generally speaking, a ceramic production needs about 30 days to finish. Some special products maybe take a longer time. For some simple products, maybe 10-15 days is ok.

6. Can you do the finish maching?

Yes, we have lathes, grinding machines, milling machines, carves-milling machines to make sure products' accuracy.
