What are Metallized Ceramics?

Metallized ceramics are ceramic components — such as substrates, insulators, rings, tubes and feedthrough bodies — with a selected metal-compatible layer (for example Mo-Mn, Ag-Pd, Cu or active-braze metallization) and optional Ni/Au or Ag plating.

This layer makes an insulating ceramic solderable and braze-ready, so it can form a strong, gas-tight ceramic-to-metal joint. They are used where a part must be electrically insulating and vacuum- or pressure-tight at the same time, such as vacuum feedthroughs, high-voltage insulators and power-module substrates.

Custom Metallized Ceramic Manufacturer

ADCERAX specializes in custom metallized ceramic components, engineered to your drawings or samples.  We support complex shapes, selective metallization areas, and precision bonding layers with full in-house control — from prototyping to mass production, typically delivered within 3–9weeks.

Customization Options

Special Dimension

Extra-large / Extra-small diameters, non-standard thicknesses, and ultra-long / ultra-short lengths.

Precision Tolerance

Provide higher - level dimensional accuracy and concentricity control than the standard.

Complex Shapes

Flanges, steps, threads, drilling holes, grooves, etc.

Special Purity

Adjust the material according to the application requirements.

Surface Finish

Polish and grind the surface to achieve a specific surface roughness.

Customization Process

Requirement Submission

Send us your drawing, CAD file, or physical sample with material grade, dimensions, tolerances, and quantity. Our engineers will evaluate the design and provide a detailed quotation with lead time and pricing.

Confirm Order & Prototype

Once the quote is approved, we proceed with sample prototyping (1–50 pcs) if needed, for testing and validation.

Mass Production & Quality Control

After sample approval or direct confirmation, we begin batch manufacturing using CNC machining, sintering, and polishing. All parts undergo dimensional checks, material purity testing, and surface finish inspection.

Packaging & Global Delivery

Finished products are securely packed and shipped via DHL/FedEx/UPS or your preferred method. We support global delivery with full documentation.

How a Metallized Ceramic Part Is Defined — 5 Layers to Confirm

Every metallized ceramic part is set by five layers. Confirm them with your drawing, and the quote checklist below maps to each one.

1

Base ceramic — alumina / AlN / Si₃N₄ / zirconia · sets CTE, insulation, temperature and the available route.

2

Metallization — Mo-Mn, Mo-Mn-W, active brazing or a conductive pattern.

3

Finish/plating — Ni, Au, Ag or Ni/Au for solderability and stability.

4

Mating metal — Kovar, stainless steel, copper, nickel or molybdenum · for CTE match.

5

Validation — helium leak, voltage, thermal cycle and adhesion / pull-shear targets.

Frequently Asked Questions About Metallized Ceramics

They are the same thing. "Metallized" (double-L) is the more common buyer spelling; "metalized" (single-L) is an alternate/URL spelling. Both mean a ceramic with a solderable, brazable or conductive metal layer.

Oxide ceramics (alumina) usually use the Mo-Mn route with Ni/Au plating; non-oxide ceramics (AlN, Si₃N₄, SiC) and many ceramic-to-metal joints use active brazing. The right route depends on the base ceramic, mating metal and application, and is set in engineering review.

Ni, Au, Ag or Ni/Au, chosen for solderability and oxidation stability. Not every part needs gold — tell us your joining method and environment.

We supply metallized ceramic parts and substrates — feedthrough bodies, metallized tubes, rings, insulators and substrates — routed to the right sub-page. We supply the ceramic-metal parts, not complete packaged devices, and match your module and interface by review.

Industry benchmarks (for example hermetic leak around ≤1×10⁻⁹ atm·cc/s) are buyer targets, not fixed ADCERAX guarantees. We confirm leak rate, voltage and bond strength by design and test method for your part — share your targets and we review feasibility.
