Electrical Insulation Al2O3 Alumina Ceramic Substrate Plates

PRODUCT DESCRIPTION

Alumina ceramic ( Aluminum Oxide or Al2O3 ) is an excellent electrical insulator and one of the most widely used advanced ceramic materials. Additionally, it is extremely resistant to wear and corrosion. Alumina components are used in a wide range of applications such as electronics & electrical, pump components and automotive sensors, medical, semiconductor, furnace parts...

UNIPRETEC offers a variety of alumina compositions, typical grades that are used for modern industrial applications are of high purity from 90% to 99.7%.

Alumina components can be formed by a variety of manufacturing techniques such as dry pressing, cold isostatic pressing, injection molding and extrusion. Finishing can be accomplished by precision grinding and lapping, laser machining, metallizing and a variety of other processes.

Overview of typical properties:

• Good electrical insulation;

• High mechanical strength;

• Excellent wear resistance;

• Excellent corrosion resistance;

• Low dielectric constant;

• High using temperature;

• High thermal shock resistance...

Overview of typical applications:

• Pump seals and other components;

• Wear resistant inserts;

• Insulating washers or bushings;

• Semiconductor components;

• Aerospace components;

• Automotive sensors;

• Electrical or electronic insulators...

FAQ

Q1: What are advanced ceramics?

>>> Advanced ceramics - also referred to as engineering, structural or technical ceramics - have been processed to be very pure and, in general, have superior properties to unrefined ceramics. Many are man-made, i.e. they do not occur naturally, e.g. silicon nitride, and their properties can be enhanced to produce very high strength at high temperatures, good corrosion resistance, etc.

Q2: What types of ceramic do you supply?
>>> Alumina in purity from 90% to 99.7%, yttria stabilized zirconia (Y-PSZ), hot pressed boron nitride, machinable glass ceramic, boron carbide, silicon nitride, mullite and cordierite.

Q3: Can I machine the ceramics myself?
>>> The harder ceramics like alumna and zirconia will require diamond tooling but other materials like Machinable Glass Ceramic and Hot Pressed Boron Nitride can be machined. To get the right result it does take time, experience and semi-specialised tooling but it can be done and many of our customers take advantage of this when they need extremely fast solutions in-house.

Q4: Can I get a sample or purchase a small quantity?
>>> Yes, we are happy to supply small samples of material for you to test. We can also supply prototype quantities through to volume production to suit your needs.

Q5: How long will it take for you to send me a quote?
>>> This depends totally on the complexity of your requirements. For simple items such as bars and rods, we can generally supply a quotation within 24 hours.

Q6: What's the delivery time?
>>> For our standard products, like ceramic protection tubes and insulating rods, delivery time is normally 7 working days. For hot pressed boron nitride and machinable glass ceramic, it's about 10 working days. For customized products made of alumina, zirconia, boron carbide and silicon nitride, total producing time is about 30 working days.
