Specification of 2mm 3mm 4mm Polished Alumina and Zirconia Ceramic Rods

Refined alumina and zirconia ceramic rods use high performance. These rods are available in typical sizes: 2mm, 3mm, and 4mm. The polished coating supplies an incredibly smooth surface area. This smoothness minimizes rubbing. This level of smoothness minimizes wear. This smoothness is critical for accuracy applications. You get constant measurements. You obtain tight resistances.

Alumina ceramic rods are very hard. Alumina rods are highly use immune. They offer excellent electric insulation. They stand up to heats well. Alumina rods take care of strong acids and alkalis. They are chemically secure. Typical pureness is 99.5%. This pureness ensures trusted buildings. These poles suit electric insulators. These rods match wear parts. These poles match lab equipment.

Zirconia ceramic rods are also harder. Zirconia provides remarkable crack toughness. Zirconia bends somewhat under pressure instead of fracturing. It has higher stamina than alumina. Zirconia supplies superior wear resistance. Zirconia stands up to influence damages better. It has a lower thermal conductivity. This aids in thermal monitoring. Zirconia works well for bearings. Zirconia works well for reducing tools. Zirconia works well for clinical parts. Zirconia functions well where high stress and anxiety happens.

Both products are completely thick. Both materials are non-porous. This stops contamination. This ensures architectural honesty. The polished surface is ready for usage. No further finishing is needed. These rods fit requiring commercial applications. These poles fit research study setups. These rods fit medical tools. They offer long life span. They perform reliably under extreme conditions. Select alumina for electrical insulation and cost-effectiveness. Choose zirconia for maximum strength and sturdiness.

5 FAQs of 2mm 3mm 4mm Polished Alumina and Zirconia Ceramic Rods

Polished Alumina and Zirconia Ceramic Rods: Key Questions Answered

Customers often ask these questions about our 2mm, 3mm, and 4mm polished ceramic rods.

What’s the difference between Alumina and Zirconia rods?
Alumina rods offer excellent electrical insulation and good wear resistance. They handle high temperatures well. Zirconia rods are much tougher. They resist cracking better under stress. Zirconia also has lower thermal conductivity. Both materials are very hard and chemically inert.

Why offer rods in 2mm, 3mm, and 4mm diameters?
These are widely used sizes. They fit many standard applications. Smaller diameters suit delicate components. Larger diameters provide more strength. Having these sizes available saves machining time. Customers get parts faster.

How smooth is the polished surface?
The surface finish is very fine. We achieve a low Ra value. Ra measures surface roughness. A lower Ra number means a smoother surface. This polish reduces friction. It minimizes wear on mating parts. It improves sealing in some uses.

What are typical applications for these rods?
They serve many precision roles. Common uses include precision shafts, wear-resistant pins, guides, insulators, and sensor components. Their smoothness helps in fluid handling. Their hardness protects against abrasion. Their stability is vital in high-heat environments.

Can you make rods in other sizes or materials?
Yes. We produce custom diameters and lengths. We work with other advanced ceramics too. Tell us your specific needs. We provide a quote quickly. Custom orders maintain the same high polish standard.
