Specification of Customized Al2o3 95 99 Alumina Insulating Ceramic Tubes
These insulating ceramic tubes are made from alumina. Alumina is aluminum oxide. We use high-purity alumina powder. We make tubes in two common grades: 95% Al2O3 and 99% Al2O3. The number shows the alumina content. Higher purity usually means better performance. These tubes are excellent electrical insulators. They resist very high voltages. This makes them safe for electrical applications.
The tubes handle extreme heat well. They work fine in temperatures over 1500°C. Their thermal shock resistance is good. They cope with fast temperature changes. Their mechanical strength is high. They are hard and resist wear. This gives them a long service life. They stay dimensionally stable under heat. Their shape does not change much.
Chemical resistance is another key point. The tubes resist attack from many acids and alkalis. They are stable in corrosive environments. This is important for harsh industrial uses. The surface finish is smooth. We can achieve precise dimensional tolerances. We control the inside and outside diameters carefully. Wall thickness is also controlled.
Customization is a big advantage. We make tubes to your specific needs. You choose the alumina grade: 95% or 99%. You specify the exact dimensions. This includes length, inner diameter, outer diameter. We can adjust the wall thickness. We meet your required surface finish. We can also meet special tolerance requests. We produce tubes in various quantities. We handle both small batches and large orders.
These tubes are used in many industries. They are common in furnaces and kilns. They protect thermocouples and heating elements. They work in semiconductor manufacturing equipment. They are found in analytical instruments. They serve in high-temperature sensors. They are essential where electrical insulation is critical at high heat. Their reliability is proven.

Applications of Customized Al2o3 95 99 Alumina Insulating Ceramic Tubes
Customized Al2O3 95% and 99% alumina insulating ceramic tubes solve tough problems in many industries. These tubes handle extreme heat very well. They keep their shape and strength even at very high temperatures. This makes them perfect for furnace linings, kiln furniture, and thermocouple protection tubes. They shield sensitive sensors from intense heat.
These ceramic tubes are excellent electrical insulators. They stop electricity from flowing. This property is vital in electronics and electrical systems. They insulate heating elements effectively. They work well in high-voltage equipment. They prevent electrical shorts in demanding settings.
Chemical resistance is another major benefit. Alumina tubes resist attack from many acids and alkalis. They don’t corrode easily. This durability is crucial in harsh chemical processing environments. They work reliably in labs handling aggressive substances. They last a long time in corrosive atmospheres.
Customization is key for these tubes. Off-the-shelf sizes often don’t fit specific machinery or processes. Manufacturers can make tubes to exact customer drawings. They control the outside diameter, inside diameter, and length precisely. They adjust wall thickness as needed. This ensures the tube fits perfectly into the final application. It avoids costly modifications later.
These tubes offer excellent thermal insulation too. They slow down heat transfer effectively. This helps maintain consistent temperatures inside equipment. It improves energy efficiency in high-temperature operations. It protects surrounding components from excessive heat. This insulation is critical in semiconductor manufacturing. It matters in heat treatment furnaces.
Mechanical strength is important. Alumina tubes are very hard and wear-resistant. They withstand physical abrasion and impact better than many materials. This suits them for demanding industrial roles. They perform well as protective sheaths. They work as sturdy guides for wires or other components. Their dimensional stability under load is reliable.
The combination of properties makes these tubes versatile. They meet requirements where metals or plastics fail. They handle heat, electricity, chemicals, and mechanical stress together. Custom sizes ensure optimal performance in the target machine or process. Industries rely on them for consistent, long-lasting operation.

5 FAQs of Customized Al2o3 95 99 Alumina Insulating Ceramic Tubes
Here are 5 FAQs about Customized Al2O3 95/99 Alumina Insulating Ceramic Tubes:
What’s the difference between 95% and 99% alumina tubes? The main difference is purity. 95% alumina tubes contain 95% aluminum oxide. 99% alumina tubes contain 99% aluminum oxide. Higher purity means better performance. 99% tubes handle higher temperatures. They resist chemical attack better. They are stronger mechanically. They offer superior electrical insulation. 99% alumina costs more. Choose based on your specific needs.
What temperatures can these tubes withstand? These tubes handle extreme heat well. Alumina 95 tubes typically work up to 1600°C. Alumina 99 tubes withstand even higher temperatures. They often work up to 1750°C. This depends on the exact conditions. The furnace atmosphere matters. The heating rate matters. The mechanical load matters. Consult the manufacturer for your exact use.
Can I get custom sizes and shapes? Yes. These tubes are often made to order. Standard sizes exist. Custom diameters are possible. Custom lengths are possible. Custom wall thicknesses are possible. Special end shapes are possible. Flanges or other features are possible. Provide your exact specifications early. This ensures manufacturability.
What surface finishes are available? Different finishes suit different needs. An as-fired surface is standard. It’s economical. It works for many applications. A ground surface is smoother. It offers tighter dimensional control. It provides a precise fit. A polished surface is also available. Polishing minimizes surface defects. Polishing improves electrical performance in some cases. Ask about the best finish for your project.
How long does production take? Production time varies. Standard sizes ship faster. Custom sizes take longer. Complex shapes take longer. High-purity 99% alumina can take longer. Surface finishing adds time. Typical lead times range from 4 to 12 weeks. Rush services might be possible. Discuss your timeline requirements upfront.
