Specification of China Factory Industrial Aluminum Oxide Alumina Ceramic Metalized Substrate

China Factory produces industrial aluminum oxide ceramic substrates. We call this material alumina. It is a high-performance technical ceramic. Our substrates feature high purity levels. This ensures consistent quality and reliability. The material composition is primarily aluminum oxide. This gives excellent electrical insulation properties. Thermal conductivity is another key advantage. It handles heat very well in demanding applications.

The ceramic surface undergoes a special metalization process. We apply a bonded metal layer to the substrate. Common metals used are molybdenum or manganese. This creates a strong, reliable connection surface. The metal layer bonds tightly to the alumina ceramic. This allows direct brazing or soldering of components. It forms a durable electrical and mechanical joint.

These metalized alumina substrates offer superior performance. They withstand very high temperatures easily. They resist thermal shock extremely well. Mechanical strength is high. Chemical resistance is excellent against harsh substances. Electrical insulation remains stable under high voltages. This combination is vital for tough industrial environments.

Typical uses include power electronics modules. They serve as bases for semiconductor devices. They are found in high-power LED assemblies. Automotive electronics rely on their durability. Industrial heating systems use them extensively. They function in high-frequency circuits effectively. Thick-film circuits are printed directly onto them. They provide a stable platform for hybrid circuits. High-voltage applications demand their insulation properties. They are essential for reliable heat dissipation. China Factory ensures strict quality control throughout production. We meet precise dimensional tolerances consistently. Surface finish quality is excellent. Our products deliver dependable performance for critical industrial systems.

Applications of China Factory Industrial Aluminum Oxide Alumina Ceramic Metalized Substrate

China factories produce industrial aluminum oxide ceramic substrates. These are also called alumina ceramics. They are made from very pure aluminum oxide powder. Factories shape and fire this powder at high temperatures. The result is a hard, dense ceramic material. This material has special properties. It handles extreme heat well. It resists chemical corrosion. It is also an excellent electrical insulator. These features make it useful in many industries.

Factories often metalize the ceramic surface. They apply a thin metal layer. This layer is usually nickel or copper. Sometimes it is a nickel-chromium mix. Metalization lets users bond the ceramic to other parts. They can solder or braze metal components directly onto it. This creates strong, reliable connections. The ceramic base provides insulation and heat management. The metal layer allows electrical connections.

Welding equipment uses these metalized substrates. They form the base for welding torch tips. The ceramic handles the intense welding heat. The metal layer connects to power cables. Automotive sensors rely on them too. Oxygen sensors in car exhaust systems use this technology. The ceramic withstands hot, corrosive exhaust gases. The metalized contacts connect the sensor to the vehicle’s computer.

Electronics need these substrates for high-power circuits. They are common in LED lighting systems. The ceramic carries heat away from the powerful LED chips. This prevents overheating. The metalized traces connect the electrical components. Power semiconductor modules use them. Think of devices controlling large motors or converting power. The alumina base insulates high voltages. It also spreads heat efficiently to cooling systems.

Thin-film circuits use metalized alumina. Engineers deposit precise circuit patterns onto the ceramic. This works for microwave devices and some medical equipment. The ceramic provides a stable, insulating base. Lasers and vacuum chambers also incorporate these substrates. They need materials that last under harsh conditions. Industrial aluminum oxide ceramics deliver this performance reliably. China factories supply these essential components globally. They offer a balance of good performance and cost.

5 FAQs of China Factory Industrial Aluminum Oxide Alumina Ceramic Metalized Substrate

What is this alumina ceramic substrate?
This is a flat piece made from industrial aluminum oxide. Factories shape and fire it into a hard ceramic. Then they add a thin metal coating onto its surface. This metal layer lets you solder electronic parts directly to the ceramic. It’s for circuits needing strength and heat handling.

Why pick alumina ceramic over other materials?
Alumina handles very high heat well. It doesn’t wear down easily. It resists electricity strongly. It moves heat fast. It stays strong under pressure. These features make it reliable for tough jobs like power electronics or high-temperature sensors. It lasts longer than many plastics or basic boards.

What thicknesses do you offer?
We make many thicknesses. Common sizes are 0.25mm, 0.5mm, 0.63mm, 1.0mm, and 2.0mm. We also handle thicker requests up to 10mm. Tell us your need. We check if we can supply it.

Can you change the size and shape?
Yes. We cut the ceramic to your exact drawing. We offer standard squares and rectangles. We also make circles, rings, or custom shapes with holes or cutouts. Send your specifications. We make it fit.

How do you ensure quality?
We test every batch. We check the ceramic density and strength. We measure the metal layer thickness carefully. We test how well the metal sticks to the ceramic. We look for cracks or flaws. We use precise tools for sizes. We give test reports with the shipment.
