Ceramic Sheet Corning Precision 0.015″ Tolerance, Zero Porosity

Description

Product Overview

The Corning ceramic sheet is engineered to meet the most demanding specifications in modern industrial and scientific applications. With a nominal thickness tolerance of +0.015″ on the positive side and no negative deviation, the sheet maintains exact dimensions that are critical for precision assemblies. The material is a high‑purity alumina ceramic, offering zero porosity and therefore eliminating any risk of outgassing, a key requirement for cleanroom and vacuum environments. Weighing only 2.4 ounces per sheet, it is lightweight yet exceptionally robust, providing excellent resistance to thermal shock, chemical exposure, and mechanical wear. The sheet is supplied by Corning Inc., a trusted name in advanced materials, and carries the ASIN B00I2UBBTO for easy reference. Its best‑seller rank in the Ceramic Sheets category reflects its popularity among engineers who need reliable, machinable ceramic components without the need for post‑firing processes.

Usage

This ceramic sheet excels in a variety of high‑performance settings. In aerospace manufacturing, the tight tolerance and dimensional stability enable the production of turbine blades, heat exchangers, and sensor housings that must endure extreme temperature cycles. Electronics manufacturers benefit from the sheet’s zero‑porosity surface, which prevents contamination in semiconductor packaging and printed circuit board substrates. In medical device fabrication, the material’s biocompatibility and inertness make it suitable for surgical instruments, implantable components, and diagnostic equipment that require strict sterility standards. The sheet’s easy machinability allows technicians to cut, drill, and shape the material using standard CNC equipment, reducing lead times and eliminating the need for costly post‑processing. Additionally, its chemical resistance makes it a preferred choice for laboratory equipment, such as reaction chambers and filtration components, where exposure to aggressive reagents is common.

FAQ

What is the exact thickness tolerance of the ceramic sheet?

The sheet is manufactured with a positive tolerance of +0.015″ and a negative tolerance of 0.000″, meaning the thickness will never be less than the nominal value and may be up to 0.015″ thicker. This tight control is achieved through precision grinding and polishing processes, ensuring consistent performance in applications where dimensional accuracy is critical.

Can the sheet be machined with standard CNC equipment?

Yes, the Corning ceramic sheet is designed for easy machinability. It can be cut, milled, and drilled using conventional CNC routers and mills equipped with carbide or diamond tooling. Because the material does not require a post‑firing heat treatment, you can complete the entire fabrication process in a single machining step, which streamlines production and reduces overall cost.

Is the material suitable for use in medical devices?

Absolutely. The ceramic is biocompatible, chemically inert, and free of porosity, which prevents bacterial colonization and ensures sterility. These properties, combined with its mechanical strength, make it an excellent choice for surgical instruments, implantable components, and diagnostic equipment that must meet stringent regulatory standards.

How does the zero‑porosity feature benefit cleanroom applications?

Zero porosity means the material has no microscopic voids that could trap particles or release gases. In cleanroom environments, this eliminates a common source of contamination, helping you maintain the required ISO class cleanliness. The sheet’s surface also resists adsorption of organic compounds, further protecting sensitive processes such as semiconductor fabrication.

What kind of after‑sales support does Corning provide?

Corning offers a comprehensive support package that includes technical consultation, machining guidelines, and material certification documents. Our engineers can assist with selecting the appropriate tooling, optimizing feed rates, and ensuring that your finished parts meet performance expectations. Additionally, we provide a warranty that covers material defects, giving you peace of mind throughout the product’s lifecycle.
