Specification of 99.5 C799 Aluminum Oxide Plate Alumina Ceramic Sheet

This 99.5% C799 Aluminum Oxide Plate offers high performance. It is made from very pure alumina ceramic. The purity level is 99.5%. This guarantees consistent material properties. The plate is extremely hard. It measures around 9 on the Mohs scale. This hardness gives it outstanding wear resistance. It withstands abrasive conditions well. Surfaces stay smooth longer. This reduces friction and material loss.

The plate handles high temperatures easily. It operates reliably up to 1600°C (2912°F). Thermal shock resistance is good. Sudden temperature changes cause less cracking. It expands very little when heated. This dimensional stability is crucial for precision parts. The material is an excellent electrical insulator. It blocks high voltage currents effectively. This prevents electrical short circuits. It works well in demanding electrical applications.

Chemical resistance is another key strength. The plate resists attack from many acids and alkalis. It holds up against molten metals. Corrosion is minimal in harsh environments. This makes it suitable for chemical processing. It also works well in furnace parts. The material is very stiff. It has a high modulus of elasticity. This means it bends very little under load. It maintains its shape under pressure. Surface finish options are available. Polished finishes reduce friction further. Standard sizes are common. Custom shapes can be manufactured.

Applications of 99.5 C799 Aluminum Oxide Plate Alumina Ceramic Sheet

99.5 C799 aluminum oxide plate, also called alumina ceramic sheet, is a top-performing material. Its hardness is very high, close to diamonds. This makes it super resistant to wear and abrasion. Parts like nozzles, liners, guides, and wear plates last much longer. Equipment downtime drops significantly. Maintenance costs go down.

This ceramic handles extreme heat extremely well. It works fine in temperatures up to 1500°C. Furnace parts, kiln furniture, and heat treatment fixtures rely on it. Thermal shock resistance is good. Sudden temperature changes cause less cracking. Performance stays stable.

Electrical insulation is another major benefit. Alumina plates don’t conduct electricity. They are perfect insulators for electronic components. High-voltage applications use them safely. Substrates for circuits and insulators in power systems are common uses. Signal integrity improves.

Chemical stability is impressive. The plate resists attack from most acids and alkalis. Corrosion is minimal. Harsh chemical processing environments use it reliably. Pump seals and lab equipment surfaces benefit. Contamination risk is low.

Surface finish can be very smooth. Precision grinding achieves tight tolerances. Flatness and parallelism are excellent. Semiconductor manufacturing tools and precision measurement devices need this. Accuracy is critical.

The material is very stiff. It doesn’t bend much under load. Dimensional stability is superb. Gauges, fixtures, and optical components keep their shape. Measurement stays precise.

Alumina ceramic is biocompatible. It works well in certain medical devices. Surgical tools and implant components use it sometimes. Biocompatibility is important there.

Different thicknesses are available. Options range from thin 0.5mm sheets up to thick 50mm plates. Custom sizes and shapes are possible. Machining adapts it to specific needs. Laser cutting and drilling are common methods. Production flexibility increases. Sensor housings often use this tough ceramic.

5 FAQs of 99.5 C799 Aluminum Oxide Plate Alumina Ceramic Sheet

What is 99.5% C799 Aluminum Oxide Plate?
This is a very pure ceramic plate. It is made almost entirely from aluminum oxide. We call it Alumina. The “99.5%” means it’s 99.5% pure. The “C799” is a specific grade. This grade is known for being strong and reliable. It’s a common industrial ceramic material.

What are the main features of this alumina plate?
This plate is extremely hard. It is harder than many metals. It resists wear exceptionally well. It handles very high temperatures easily. You can use it over 1600°C. It is also a very good electrical insulator. Electricity does not pass through it easily. It resists chemical attack from many things. Acids and bases often don’t harm it. It is dimensionally stable too. It doesn’t change size much with heat.

Where is this ceramic sheet typically used?
People use it in many tough jobs. It’s common for wear parts. Things like liners, guides, and chutes use it. It protects surfaces from getting scraped. It’s used in high-temperature settings. Furnace parts and insulation supports need it. Electronics use it for insulating substrates. Circuit carriers and sensor bases need good insulation. It’s also used in chemical processing equipment. It holds up against corrosive materials.

Why does the plate thickness matter?
Thickness is critical for performance. Thicker plates are stronger mechanically. They handle heavier loads better. They resist breaking under pressure. Thinner plates are better for electrical uses. They manage heat flow differently. Thinner plates might be more flexible in some cases. The right thickness depends on the job. You must choose based on your specific needs.

How should I handle and install this plate?
Handle it carefully. Alumina ceramic is hard but brittle. It can chip or crack if hit hard. Avoid dropping it or striking it. Use appropriate tools for cutting. Diamond tools work best. Drilling requires special care. Support the plate well during machining. Secure it firmly during installation. Prevent any bending or twisting stress. Ensure surfaces are clean and flat. Use suitable adhesives or mechanical fasteners designed for ceramics.
