Specification of Industry ceramic alumina rod

Our industry ceramic alumina rods are made from high-purity aluminum oxide. This gives them excellent properties for tough jobs. The alumina content (Al2O3) is usually over 95%. Some grades reach 99%. This high purity ensures strong performance.

These rods handle heat very well. They operate reliably at temperatures exceeding 1600°C. They resist thermal shock effectively. Sudden temperature changes don’t easily crack them. Chemical corrosion resistance is another key benefit. Acids and alkalis cause minimal damage. Harsh environments are no problem.

Mechanical strength is impressive. The rods are very hard. They resist wear and abrasion superbly. Heavy loads won’t easily break them. Electrical insulation properties are outstanding. High voltages pass safely around them. This is vital in electrical uses.

Surface finish options exist. We supply rods with smooth polished surfaces. We also supply rods with precise ground finishes. Dimensional accuracy is guaranteed. Standard diameters range from 3mm up to 50mm. Lengths can reach 1000mm. Custom sizes are possible. We meet specific customer requirements.

Tight tolerances are standard. Diameter tolerance is typically ±0.1mm. Length tolerance is usually ±0.5mm. Straightness is carefully controlled. This ensures easy installation. Consistent performance is the result.

Applications of Industry ceramic alumina rod

Ceramic alumina rods are incredibly tough. They handle extreme heat easily. This matters in industrial kilns and furnaces. They form essential parts like thermocouple protection tubes. These tubes shield sensors measuring high temperatures accurately. Alumina rods also work well for supporting hot items inside furnaces. They don’t sag or melt under intense heat.

Electrical insulation is another key feature. Alumina rods don’t conduct electricity. This makes them safe near high voltages. Welding equipment often uses them. They position electrodes precisely without short circuits. Foundries use them for handling molten metal safely. Workers avoid electric shocks.

These rods are also very hard and resist wear. They last long in abrasive conditions. Cutting tools sometimes use alumina rods as guides. They keep blades stable and precise. Textile machinery employs them as durable guides for threads or fibers. Constant friction doesn’t wear them down quickly.

The semiconductor industry relies on alumina rods too. They are chemically inert. They don’t contaminate sensitive processes. Alumina rods handle silicon wafers during manufacturing. They provide stable, clean support. Labs use them for sample holders in high-temperature testing. The material purity is critical here.

Alumina rods manage thermal shock well. Sudden temperature changes don’t crack them. This is vital for rapid heating or cooling tasks. They are dimensionally stable. Their size and shape stay consistent under stress. Engineers trust them for precise setups. They offer reliability in demanding factory settings.

5 FAQs of Industry ceramic alumina rod

What is ceramic alumina rod made from?
It’s pure aluminum oxide. This material gets fired at very high temperatures. That process makes it extremely hard and durable. It’s like super-strength ceramic.

How hot can it get before failing?
It handles temperatures up to 1800°C. That’s really hot. Most metals melt way before that point. This rod keeps its shape and strength. It’s built for furnaces and kilns.

Where is this rod typically used?
Factories use it in high-heat zones. Think kiln furniture, furnace parts, and thermocouple protection tubes. It works in places needing heat resistance and electrical insulation. Semiconductors and metallurgy rely on it.

What sizes and shapes are available?
You get standard rounds from 2mm to 50mm diameter. Lengths go up to 500mm or longer sometimes. Custom shapes are possible too. Ask the manufacturer for specific needs.

Is it fragile? How careful must I be?
It’s rigid and handles heat well. But it can crack under sharp impact or sudden temperature drops. Avoid banging it. Heat and cool it gradually. Handle it like fine china.
