Specification of 1mm 2mm 3mm 4mm 5mm 95% 99% Al2O3 Alumina Ceramic Rods

These alumina ceramic rods deliver exceptional performance for demanding industrial uses. Available diameters include 1mm, 2mm, 3mm, 4mm, and 5mm. You choose between two high purity levels: 95% Al2O3 or 99% Al2O3. The higher purity option offers superior performance characteristics.

These rods are incredibly hard. They resist wear extremely well. This makes them perfect for parts facing constant friction. Their high hardness gives them excellent abrasion resistance. They maintain dimensional stability even under heavy load.

Heat resistance is another major benefit. Alumina ceramic rods handle very high temperatures easily. They are stable in environments exceeding 1500°C. This thermal stability prevents warping or cracking during rapid temperature changes. They are ideal for furnace components and high-temperature sensors.

Chemical inertness is a key feature. These rods resist attack from most acids and alkalis. They won’t corrode in harsh chemical environments. This makes them suitable for chemical processing equipment and labware. They provide long-lasting service without degradation.

Electrical insulation properties are outstanding. Alumina ceramic is an excellent electrical insulator. It works well even at elevated temperatures. This is crucial for electrical feedthroughs, insulators, and electronic substrates. You get reliable insulation performance.

The rods offer good mechanical strength. They are rigid and maintain their shape under pressure. Manufacturing ensures tight dimensional tolerances. Surface finishes are typically smooth for precision applications. Common uses include guides, bearings, shafts, insulators, and wear components. They are found in industries like aerospace, semiconductors, medical devices, and energy. Their combination of hardness, heat resistance, and chemical stability is hard to match.

Applications of 1mm 2mm 3mm 4mm 5mm 95% 99% Al2O3 Alumina Ceramic Rods

These alumina ceramic rods come in sizes from 1mm to 5mm diameter. They are available in two purity grades: 95% and 99% Al2O3. Both grades are highly useful in many demanding applications. Their key properties drive their use.

Electrical insulation is a major strength. Alumina ceramic rods are excellent insulators. They work well in high-voltage environments. They are common in spark plugs, insulators for sensors, and feedthroughs in electronic housings. Their stability prevents electrical leakage. This is critical for safety and performance.

Thermal management is another key area. Alumina handles high temperatures extremely well. These rods are used as thermocouple protection tubes. They shield delicate sensors in furnaces and engines. They also serve as spacers in high-heat assemblies. They maintain position and electrical isolation without degrading.

Wear resistance is vital for moving parts. The hardness of alumina ceramic rods makes them resistant to abrasion. They function well as guides for wires or fibers. They are used in textile machinery and wire drawing processes. They minimize friction and wear on other components. This extends equipment life.

Chemical stability is essential in harsh environments. Alumina ceramic rods resist attack from many acids and alkalis. They are suitable for chemical processing equipment. They can be used as stirrers or sample holders in corrosive liquids. They do not contaminate the process.

The purity level matters. 99% alumina offers higher density and better performance. It has superior mechanical strength. It provides better electrical insulation at extreme temperatures. It offers improved corrosion resistance. It is the choice for the most critical applications. 95% alumina is still very capable. It is a cost-effective solution for many demanding situations. It performs well where the absolute maximum properties of 99% are not strictly required.

Size dictates specific roles. Thin 1mm and 2mm rods are perfect for delicate instrumentation. They fit into small spaces. They work as probe tips or micro-components. 3mm and 4mm rods offer a good balance. They provide strength while maintaining a compact form. They are often used as sensor elements or insulating pins. Thicker 5mm rods deliver maximum rigidity. They handle heavier mechanical loads. They are ideal for structural spacers or robust guides.

5 FAQs of 1mm 2mm 3mm 4mm 5mm 95% 99% Al2O3 Alumina Ceramic Rods

Here are common questions about our alumina ceramic rods:

What sizes do these rods come in?
We offer precise diameters from 1mm up to 5mm. Stock includes 1mm, 2mm, 3mm, 4mm, and 5mm rods. Custom lengths are available too.

What’s the difference between 95% and 99% Al2O3?
The number shows the alumina purity. 99% Al2O3 rods are denser and harder. They handle higher temperatures better. 95% Al2O3 rods are strong and cost less. Choose 99% for extreme conditions. Choose 95% for good performance at a lower price.

How much heat can these rods take?
Both purities resist very high heat. 99% Al2O3 rods withstand temperatures near 1800°C. 95% Al2O3 rods handle temperatures near 1600°C. They won’t melt or degrade easily in furnaces or high-heat tools.

Do they conduct electricity?
No. These alumina rods are excellent electrical insulators. They block electric current even at high temperatures. This makes them safe for electrical parts and sensors.

Where are these rods typically used?
They are used in many industries. Common uses include thermocouple protection tubes, furnace fixtures, lab equipment, and insulating components in electronics. Their hardness makes them good for wear-resistant parts.
