Here’s the product description for alumina porous ceramic discs:

These alumina porous ceramic discs are for vacuum chucks. They are made from high purity Al2O3. This material is very strong. It handles high temperatures well. The discs resist chemical attack. This makes them reliable in tough conditions.

You get discs in many sizes. Choose from 4 inches, 6 inches, 8 inches, 9 inches, or 12 inches. We also list them as 4″, 6″, 8″, 9″, and 12″. Need a different size? Ask us. We make custom sizes too.

The porous structure is key. It allows air to flow through smoothly. This creates a strong vacuum hold. Your workpiece stays firmly in place. The vacuum seal is excellent. The surface is flat and precise. This ensures even contact with your material.

These discs work perfectly for vacuum chucks. They are especially good for holding delicate parts. They are ideal for the semiconductor industry. Electronics manufacturing uses them a lot. Any application needing secure vacuum holding benefits.

The discs are very hard. They resist wear over time. They maintain their shape and porosity. This gives long service life. Cleaning is easy. They handle repeated use without degrading.

Performance is consistent. The material properties are stable. You get predictable vacuum results every time. This is critical for precision work. Reliability is built in.

Applications of 4inch 6inch 8inch 9inch 12inch 4″ 6″ 8″ 9″ 12″ Alumina Al2o3 Porous Ceramics Disc / Plate for Vacuum Chuck

Alumina porous ceramic discs work well in vacuum chucks. These discs are made from Al2O3. They have many tiny holes. Vacuum chucks hold parts firmly during machining. The vacuum pulls air through the ceramic disc. This suction holds the workpiece securely. Different sizes fit different jobs.

The 4-inch and 6-inch discs are small. They are good for tiny parts. Electronics manufacturing uses these sizes often. Small sensors need reliable holding. These ceramics provide that. They are stable and precise.

Larger sizes like 8-inch and 9-inch discs handle bigger parts. General machining uses these frequently. They offer a good balance. They hold medium parts securely. They are common in workshops.

The 12-inch discs are the largest. They manage very large, heavy components. Industrial applications need this size. Big metal plates require strong holding power. These discs deliver that strength.

Alumina ceramic is strong. It handles high temperatures easily. Machining creates heat. This material stays stable. It resists chemicals well. Coolants and oils don’t damage it. This ensures long life. The discs stay flat over time. Flatness is critical for precision. Parts must not move during cutting or grinding. These ceramics keep parts fixed accurately.

The porous structure is key. Air flows through consistently. This creates even suction across the whole chuck surface. The workpiece stays flat against the chuck. Vibration is reduced. This improves machining results. Surface finishes are better. Tolerances are tighter. Broken tools happen less often.

These ceramics wear slowly. They last much longer than other porous materials. Downtime is reduced. Maintenance costs are lower. They are a reliable choice for demanding production.

5 FAQs of 4inch 6inch 8inch 9inch 12inch 4″ 6″ 8″ 9″ 12″ Alumina Al2o3 Porous Ceramics Disc / Plate for Vacuum Chuck

What are these porous ceramic discs for?
They create vacuum suction on chucks. Vacuum chucks hold workpieces tight during machining or electronics work. These discs let air pull through their tiny holes. This creates the holding force. They are rigid. They handle high heat well. Plastic alternatives warp or melt. These stay flat and strong.

What sizes do you offer?
We stock common sizes: 4 inch (4″), 6 inch (6″), 8 inch (8″), 9 inch (9″), and 12 inch (12″). These fit most standard vacuum chucks. Need a different size? We make custom sizes too. Tell us your requirements.

How thick are the discs?
Thickness depends on the disc size and your vacuum power. Common thicknesses range from 3mm to 10mm. Thicker discs are stronger. They resist cracking under heavy loads. Thinner discs allow stronger airflow. We help choose the right thickness for your pressure needs. Custom thicknesses are possible.

Is the surface smooth?
We offer different finishes. One side is usually polished very flat. This ensures a perfect seal against your chuck base. Vacuum leaks won’t happen. The other side might be less polished. This provides good grip for your workpiece. Both sides are functional. The key is the seal quality.

Will these work with my vacuum chuck?
Yes, if your chuck uses porous ceramic discs. These discs fit metal or plastic chuck bodies. They replace worn or broken discs. Check your chuck’s size and thickness first. Match our sizes to yours. They work with most vacuum pump systems. Avoid using them directly on porous workpieces.
