Specification of Aluminum Oxide Polished Ceramic Tubes, Shafts & Tubing

Aluminum oxide ceramic tubes, shafts, and tubing offer excellent performance. This material is also called alumina. It is very hard and resists wear well. It handles high temperatures easily. It also insulates electricity effectively. These parts are polished for a smooth surface. The polish reduces friction and improves fit.

The material is mostly aluminum oxide. High-purity grades are common. These grades are over 99% alumina. This high purity boosts strength and stability. Density is high. It usually measures around 3.9 grams per cubic centimeter. This makes the parts strong and durable.

Hardness is a key feature. Alumina is extremely hard. It rates about 9 on the Mohs scale. This means it resists scratches and abrasion. Compressive strength is also high. Parts withstand heavy loads without breaking. Flexural strength is good. This allows bending without damage under stress.

Thermal properties are impressive. Alumina handles high heat. It works well above 1000 degrees Celsius. Thermal shock resistance is fair. Sudden temperature changes may cause cracking. Use care with rapid heating or cooling. Thermal expansion is low. Size changes little with temperature shifts.

Electrical insulation is reliable. Alumina does not conduct electricity. It maintains insulation even at high temperatures. This is vital for electrical applications. Surface finish is critical. Polishing creates a very smooth surface. Typical roughness is very low. It might be less than 0.4 micrometers Ra.

Many sizes are available. Outer diameters vary widely. Inner diameters also differ. Wall thicknesses change to suit needs. Lengths can be customized. Common applications include industrial machinery. They are used in semiconductor tools. They appear in medical devices. They work well in high-temperature furnaces. They are found in precision instrumentation.

Applications of Aluminum Oxide Polished Ceramic Tubes, Shafts & Tubing

People use aluminum oxide polished ceramic tubes, shafts, and tubing in many tough jobs. These ceramic parts are very hard. They resist wearing down. They handle high heat well. They do not react easily with chemicals. These properties make them strong and reliable.

Many industries need these ceramic pieces. Factories use them in machines. They work well in pumps and valves. They move liquids or powders without wearing out fast. The smooth surface helps things slide easily. This reduces friction. This saves energy. It makes machines last longer.

The electronics business uses these ceramics too. They are good insulators. They keep electricity where it should be. People put them in sensors and other devices. The ceramic parts handle heat from electronics. They stay stable and do not break easily. This is important for precise electronic work.

Medical tools sometimes use these ceramics. They are safe for the body. They do not react with body fluids or cleaning chemicals. Doctors use them in special equipment. The smooth finish is easy to clean. This keeps things sterile.

Labs need strong materials. Scientists use polished ceramic tubes and shafts in experiments. They hold hot things. They handle strong chemicals. They do not contaminate samples. This helps get accurate test results.

People choose aluminum oxide polished ceramics for demanding tasks. They last longer than many metals. They work better than plastics in hot or rough conditions. They provide a smooth, tough surface. This makes many industrial processes run better.

5 FAQs of Aluminum Oxide Polished Ceramic Tubes, Shafts & Tubing

What makes aluminum oxide polished tubes special? Alumina ceramic offers extreme hardness. This hardness resists wear far better than steel or plastic. The polished surface finish minimizes friction. Less friction means components move smoothly. This reduces energy loss and heat buildup. These tubes handle tough environments well. High temperatures won’t melt them. Strong chemicals won’t easily damage them. They are also electrical insulators. This stops stray currents.

Where are these ceramic tubes typically used? You find them in machines needing reliable motion. Semiconductor equipment uses them for precise parts. Medical devices need clean, non-reactive materials. These tubes fit well. High-temperature furnaces use them as support rods. They won’t deform under heat. Optical and laser systems use them for stable alignment. Automation machinery uses them for wear-resistant guides and shafts.

How precise are the dimensions? Manufacturers control dimensions tightly. The polishing process maintains exact sizes. This is vital for fitting parts together correctly. You get consistent outer diameters and inner bores. Straightness is also tightly controlled. This ensures parts run true without wobbling. Precision grinding after firing achieves this. We measure dimensions carefully before shipping.

Can these tubes be made to custom sizes? Yes, suppliers often offer custom production. You can order specific diameters. You can order specific lengths. You can order specific wall thicknesses. Special tolerance levels are possible too. Discuss your exact needs with the supplier. They can advise on feasibility and lead times. Custom sizes work well for unique applications.

How are they installed or handled? Handle polished alumina tubes carefully. Their hardness makes them brittle against sharp impacts. Avoid dropping them onto hard surfaces. Use proper mounting techniques. Avoid forcing them into place. Support them adequately to prevent bending stress. Clean surfaces thoroughly before assembly. Debris can scratch the polished finish. Proper handling ensures long service life.
