Specification of Industrial Polished 99 Alumina Ceramic Sleeve

Industrial polished alumina ceramic sleeves use top efficiency. These sleeves include 99% pure aluminum oxide. They are unbelievably strong and challenging. They stand up to wear and rust effectively.

These sleeves come in many sizes. Common external diameters vary from 3mm to 150mm. Internal sizes start around 1mm. Lengths vary from 5mm to over 500mm. Custom dimensions are readily available. The surface area coating is extremely smooth. Sprucing up accomplishes a Ra roughness below 0.2 micrometers. This smooth surface lowers friction. It stops material sticking. The shade is pure white.

The material firmness is really high. It measures about 9 on the Mohs range. This firmness makes them immune to abrasion. They last a very long time in extreme conditions. They manage high pressure well. The compressive stamina goes beyond 2200 MPa. The flexural toughness is over 330 MPa.

These sleeves stand up to extreme warmth. They operate continually as much as 1650 ° C. They manage short bursts up to 1700 ° C. This thermal security avoids fracturing. They resist sudden temperature level changes. The thermal development coefficient is reduced. This guarantees dimensional stability.

Electrical insulation is exceptional. The dielectric stamina is high. They function well in electrical applications. Chemical resistance is impressive. Acids and alkalis do not damage them. They are inert to most chemicals. This makes them appropriate for harsh atmospheres.

The material is very dense. Density is about 3.9 g/cm THREE. This dense structure obstructs gases and fluids. It enhances the mechanical toughness. Water absorption is near absolutely no. This protects against swelling or weakening. The brightened surface area seals the structure even more.

These sleeves are accuracy components. They are utilized sought after industries. Applications consist of semiconductor handling. They are common in heating system components. They function well in pump seals. They are suitable for high-temperature bearings. They provide trusted insulation in electric systems.

Applications of Industrial Polished 99 Alumina Ceramic Sleeve

Industrial polished 99 alumina ceramic sleeves resolve hard troubles in manufacturing facilities. These sleeves are made from extremely pure, hard ceramic. They obtain a special smooth finish. This makes them exceptionally challenging and slippery.

Factories use these ceramic sleeves to protect steel components. Abrasive products wear down metal quick. The ceramic sleeve takes the pounding instead. This happens inside pumps moving sand, mud, or other abrasive fluids. The sleeve shields the pump shaft. This defense makes pumps last much longer. It saves cash on repair work and stops production.

The sleek surface area is key. It creates a barrier versus sticky stuff. Molten metal, plastic, or glue will not cling to it quickly. This keeps production lines running smoothly. Machines need much less cleansing and jam much less typically. Guides for cables, cable televisions, or fibers often make use of these sleeves. The smooth ceramic avoids grabs and decreases rubbing. This helps products relocate easily without damages.

These sleeves handle heat exceptionally well. They work great in ovens or near warm machinery. They also work great in very chilly locations. Temperature modifications don’t split them. They withstand nearly all solid chemicals. Acids and bases will not eat away at them like steel. This makes them risk-free for chemical plants and laboratories.

Power doesn’t travel through alumina ceramic. This makes the sleeves perfect insulators. They securely different parts in electrical equipment. They stop dangerous stimulates or shorts. The material is also risk-free for food and medicine. It will not respond or contaminate items. Semiconductor manufacturers utilize them since they are spick-and-span. They do not drop fragments right into sensitive procedures.

5 FAQs of Industrial Polished 99 Alumina Ceramic Sleeve

What material makes this ceramic sleeve?
Industrial Polished 99 Alumina Ceramic Sleeve uses over 99% pure aluminum oxide. This high purity delivers excellent performance. It resists wear, heat, and chemicals very well.

Why is the polished surface important?
The fine polishing creates an exceptionally smooth surface. This smoothness minimizes friction. Reduced friction means less wear on moving parts inside the sleeve. It also prevents material sticking or buildup.

How hot can it get before failing?
This alumina sleeve handles very high temperatures. It works reliably up to 1650°C (about 3000°F). Its thermal stability is excellent. This makes it suitable for demanding furnace or high-heat industrial processes.

Is it good for electrical insulation?
Yes, this is a major benefit. The high-purity alumina is an outstanding electrical insulator. It provides reliable insulation even at high voltages. This protects equipment and improves safety.

Where are these sleeves typically used?
They fit many tough industrial jobs. Common uses include thermocouple protection tubes, sensor housings, furnace liners, and high-wear bushings. They perform well in semiconductor equipment, heat treatment, and chemical processing. Their strength and durability are key in harsh settings.
