5 FAQs of Metallized 95% Alumina Ceramic Parts

What are Metallized 95% Alumina Ceramic Parts?
These are parts made from a special ceramic. The ceramic itself is 95% aluminum oxide (alumina). This makes it very hard and resistant to wear. It also handles high temperatures well. It insulates electricity effectively. A thin metal layer is applied to specific areas of the ceramic part. This layer is usually nickel or a nickel alloy. This process is called metallization.

Why put metal on the ceramic?
The metal layer allows the ceramic part to be joined to metal components. This is crucial. Brazing or soldering techniques can create strong, airtight seals. This joining is essential for assemblies needing reliable electrical insulation. It also prevents leaks in vacuum or high-pressure systems. The ceramic part cannot be joined to metal without this metallization.

Where are these parts used?
You find them in demanding electrical and electronic applications. They are common in high-power devices. Think power transmission systems, lasers, and semiconductor manufacturing equipment. They are vital in aerospace sensors. They work well in vacuum feedthroughs. They are excellent for situations needing electrical insulation plus high heat or wear resistance. They are also used in medical devices.

Why choose this over metal parts?
Alumina ceramic offers unique advantages. It withstands much higher temperatures than most metals. It doesn’t conduct electricity, which is critical for safety and function. It resists chemical corrosion better. It’s harder and more wear-resistant. It handles high voltages without breaking down. The metallization allows it to integrate into metal systems. Metal parts cannot match these specific properties.

Any special handling needed?
Yes, be careful. The ceramic base material is very hard but also brittle. Avoid sharp impacts or point loading. Dropping it can cause cracks or chips. Handle the metallized surface carefully. Protect it from scratches before joining. Follow the brazing or soldering procedures exactly. The right process ensures a strong, reliable bond. Improper joining can damage the part or create weak seals. Store parts securely to prevent damage.
