Specification of 99% Alumina Electrical Ceramic Sheet Plate Substrate

This alumina ceramic sheet is 99% pure. It provides impressive electric insulation. This material withstands high voltages perfectly. You can use it reliably sought after electrical applications. The ceramic stands up to very heats. It does well up to 1600 ° C. It likewise takes care of extremely low cryogenic temperatures. This broad array is a major advantage.

The material is extremely hard. It determines around 9 on the Mohs scale. This solidity provides it exceptional wear resistance. Surfaces remain smooth much longer. The density is high, concerning 3.9 g/cm FIVE. This adds to its toughness and toughness. Its mechanical stamina goes over. It withstands flexing and damaging efficiently.

Thermal conductivity is great. It moves warmth successfully far from elements. This stops hot spots. The thermal growth rate is extremely low. It stays dimensionally stable under warm tension. This security stops splitting. Thermal shock resistance is high. Unexpected temperature level adjustments will not quickly harm it.

Surface area surface alternatives are readily available. Sprucing up achieves a near-mirror surface. Grinding gives a regulated, smooth surface. Great grinding offers a Ra value under 0.2 micrometers. This is very smooth. The ceramic is chemically inert. It resists most acids and alkalis well. It does not corrode easily. This guarantees long-lasting dependability in severe setups. It is a suitable substrate for thick movie circuits. It sustains hybrid microelectronics accurately. It performs better than plastic or steel substratums popular functions.

Applications of 99% Alumina Electrical Ceramic Sheet Plate Substrate

99% alumina electric ceramic sheet plate substrates offer numerous essential roles in contemporary electronic devices. People rely upon them greatly since they are excellent electrical insulators. This residential property quits electrical energy leakages and stops brief circuits. This makes them excellent for shielding components in high-voltage equipment. Believe power transmission systems and huge industrial machines. They handle high voltages safely.

These ceramic sheets handle warm incredibly well. They don’t melt or warp quickly under extreme heat. This thermal stability is critical. Electronics usually produce significant warm during operation. Elements require reputable bases that won’t fall short. Alumina substratums offer that solid foundation. They are common in power electronic devices, automotive systems, and aerospace applications. High temperatures are regular there.

The material functions perfectly for LED lights and circuit boards too. Its smooth surface is ideal for mounting delicate LED chips. It successfully pulls warm away from the LED. This expands the light’s life expectancy and maintains performance strong. For circuit card, alumina provides a rigid, stable platform. It deals with requiring atmospheres better than basic products. RF/microwave circuits benefit significantly from its steady electric residential properties. Signal loss remains reduced.

Machinability is another key advantage. Suppliers can specifically cut and shape these sheets. They create complex parts with tight resistances. This flexibility matches custom layouts and high-precision requirements. The material is very hard and stands up to wear successfully. It lasts a long period of time in challenging conditions. Its chemical resistance is impressive. Rough chemicals won’t easily harm it. This suits demanding commercial settings.

Alumina ceramic substratums are crucial for trustworthy, high-performance electronic devices. They resolve important problems with insulation, warmth, and resilience.

5 FAQs of 99% Alumina Electrical Ceramic Sheet Plate Substrate

This alumina ceramic sheet handles extreme conditions in electronics. Here are key questions answered:

What’s the maximum temperature it takes?
This alumina ceramic handles up to 1600°C continuously. It won’t melt or weaken significantly near that point. This makes it safe for very hot environments like furnaces or high-power devices. Other materials often fail much sooner.

How good is it at stopping electricity?
It’s an excellent electrical insulator. Its dielectric strength is very high. This means it reliably blocks high voltages. You can use it safely in circuits carrying significant power. It prevents short circuits effectively.

How smooth is the surface?
The surface finish is very fine. The typical Ra value is under 0.8 micrometers. This smoothness is critical. It allows precise printing of circuit traces directly onto the ceramic. Rough surfaces cause printing problems.

Where is it mostly used?
Its main job is as a substrate. It holds electronic circuits and components. You find it in power modules, LED lights, heaters, and sensors. It provides a stable, non-conductive base. Heat doesn’t warp it easily.

Can I get different sizes and thicknesses?
Yes. Manufacturers offer many standard sizes. Common thicknesses range from 0.5mm up to several millimeters. They also cut custom shapes and sizes. Tell them what you need. They can usually make it.
