Specification of Al2O3 Alumina Engineering Ceramic Thin Substrate / Sheet / Plate / Board

Al2O3 alumina ceramic substrates use trustworthy performance. These slim plates can be found in several pureness grades. Common options are 96% and 99.5% pure alumina. Greater purity usually means far better efficiency. It improves electrical insulation and chemical resistance. Thickness alternatives are extremely crucial. You can find sheets from 0.1 mm approximately several millimeters thick. Standard densities consist of 0.25 mm, 0.5 mm, 0.635 mm, 1.0 mm. Custom-made thicknesses are commonly possible. Dimension matters for your application. Requirement sheets are readily available alike dimensions like 100mm x 100mm or 150mm x 150mm. Bigger dimensions are additionally manufactured. Surface area surface impacts feature. These substrates have a really smooth surface area. Typical surface area roughness (Ra) is less than 0.4 micrometers. This smoothness is essential for accurate applications. It makes certain good get in touch with and bonding.

Alumina ceramic manages heats well. It stands up to temperature levels surpassing 1500 ° C. This makes it excellent for requiring thermal atmospheres. Warmth won’t conveniently damage it. Electric homes are outstanding. Alumina is a solid electric insulator. It quits electrical energy flow successfully. This avoids brief circuits. Its dielectric stamina is high. Voltage breakdown is not likely. Mechanical toughness is excellent. Alumina ceramic is tough and inflexible. It resists wear and scraping. It supplies good compression toughness. It takes care of heavy lots without damaging. Chemical resistance is another advantage. Alumina withstands assault from several acids and alkalis. It won’t corrode quickly. This makes sure long-lasting integrity in extreme conditions. Thermal conductivity is moderate. It relocates warmth away quick adequate for numerous uses. This aids avoid overheating spots. Dimensional stability is vital. Alumina ceramic expands extremely little with warmth. Its thermal expansion coefficient is reduced. This keeps components stable and straightened throughout temperature modifications.

5 FAQs of Al2O3 Alumina Engineering Ceramic Thin Substrate / Sheet / Plate / Board

What exactly is Al2O3 alumina ceramic substrate?
It’s a thin, flat piece made from aluminum oxide ceramic. Manufacturers shape and fire pure alumina powder at high temperatures. This process creates an extremely hard, stiff material. It looks like a smooth, flat plate or sheet. People often call it an alumina board or plate.

Why pick alumina ceramic over other materials?
Alumina ceramic offers key advantages. It handles very high heat without damage. It resists chemical attack from strong acids and bases well. This material is incredibly hard, making it highly wear-resistant. It’s also a strong blocker of electricity, crucial for electronics. Its stiffness provides excellent support. These traits make it reliable for tough jobs.

How hot can this alumina substrate get?
Alumina ceramic handles extreme temperatures easily. It works fine continuously up to around 1600°C (2912°F). Short bursts can go even higher. It doesn’t melt until over 2000°C (3632°F). Its strength stays good even when very hot. This makes it perfect for furnaces, sensors, and high-heat electronics.

Is it good for electrical insulation?
Yes, alumina is a top choice for blocking electricity. It has very high electrical resistivity. This means electricity struggles to pass through it. Even at high temperatures, it blocks electricity effectively. This prevents short circuits in electronic parts. It’s a key insulator in power electronics and circuit boards.

Can the surface finish be customized?
Yes, the surface finish can be tailored. Common finishes are polished smooth or left slightly rough. Polished surfaces are flat and shiny. Rougher finishes provide better grip or bonding for coatings. Thickness and dimensions can be made to your exact needs. This ensures the substrate fits perfectly into your specific device or application.
