Specifications of Polished 99% Alumina Ceramic Rod Al2O3 Shaft

Polished 99% Alumina Ceramic Rods (Al2O3 Shafts) use exceptional performance popular applications. These rods are made from high-purity light weight aluminum oxide. This makes certain solid resistance to use and corrosion. The material remains stable under high warmth. It handles temperature levels up to 1600 ° C conveniently. This makes it suitable for furnace parts or thermal handling devices.

The poles include a precise cylindrical shape. Standard sizes vary from 1mm to 150mm. Sizes can be personalized. Common lengths rise to 500mm or even more. Tight dimensional tolerances are basic. Size resistance is frequently within ± 0.01 mm. Straightness is carefully managed. This accuracy is crucial for dependable shaft performance.

Alumina ceramic is very difficult. It ranks simply below ruby on the hardness range. This solidity provides impressive abrasion resistance. It shields the pole surface in severe atmospheres. The material has high compressive stamina also. It endures hefty tons without flawing. Its flexural strength benefits a ceramic. This provides some resistance to bending forces.

Electric insulation homes are superb. Alumina ceramic is a solid dielectric. It avoids electric existing flow efficiently. This is essential in electronic or high-voltage setups. The poles are chemically inert. They stand up to strike from lots of acids and antacids. This ensures long life in destructive conditions.

An essential function is the sleek surface finish. The surface is carefully ground and polished. This attains a really smooth, low-friction surface. Decreased rubbing minimizes endure mating parts. A smooth surface additionally improves securing capacity. It aids avoid fragment generation. This is critical in cleanroom or semiconductor applications. Surface roughness (Ra) is normally listed below 0.2 micrometers.

5 FAQs of Polished 99% Alumina Ceramic Rod Al2O3 Shaft

What is a polished 99% alumina ceramic rod?
It’s a very hard, round bar made mostly from aluminum oxide (Al2O3). We grind it smooth for a fine finish. This smoothness helps reduce friction. It’s great for tough jobs.

Why choose alumina ceramic for rods?
Alumina ceramic is very hard. It resists getting worn down. It handles high heat well. It doesn’t rust or react with chemicals. It’s also a good electrical insulator. These traits make it reliable.

Where are these polished rods typically used?
You see them in machines needing smooth, strong parts. They work as shafts in pumps. They guide material in factories. They hold things in high-temperature furnaces. They are also used in electrical devices.

What sizes do these rods come in?
We make rods in many diameters and lengths. Common diameters range from a few millimeters up to around 50 millimeters. Lengths can be short pieces or several meters long. We can often cut rods to your exact needs.

Are there handling precautions?
Yes. Alumina ceramic is very hard but can break if hit hard. Avoid dropping it or hitting it sharply. Protect the polished surface from deep scratches. Wear gloves to keep it clean during installation. Handle it carefully like glass.
