Core Capabilities
With core competencies in ceramic metallization, high-temperature brazing, and metal-based coatings, Sigma Advanced Materials is uniquely positioned to provide integrated ceramic services that make the most out of your design.
We think strategically at the outset of a project to consider your needs and resources for the best return on investment.
We have extensive knowledge in technical ceramics, with particular expertise in working with Alumina, Aluminum-Nitride, Zirconia, Steatite, Boron Nitride, and Beryllium Oxide as well as Quartz, Sapphire, and transparent ceramics.
Metallization Services
Thick film coatings are commonly used with technical ceramics to produce thermally-superior, protected components for electronic and industrial applications. But Sigma Advanced Materials definitely does not take a common approach to application processes.
Our metallization systems involve proprietary formulations and deposit methodologies that deliver superior joining bonds and strength. We work with a wide-array of conductive materials including:
REFRACTORY METAL SYSTEMS
Molybdenum-Manganese
Tungsten
CONDUCTORS
Copper
Palladium
Silver
DIELECTRIC COATINGS
Active Braze Alloys
Inconel
Glass
Polymers
High Temperature Brazing
Technical ceramics and glasses may be joined with metal sub-components through the process of brazing. Using metal-based alloys, high temperature brazing (up to 1600 deg C) creates a hermetic seal between the metal and ceramic, enabling the creation of critical technical assemblies. These may be employed in a variety of ways thanks to their strength, corrosion and wear resistance, electrical and thermal resistance, and biocompatible applicability.
Sigma Advanced Materials employs both Hydrogen and Vacuum Brazing systems, depending upon the effort required for wettability. We work with a wide spectrum of standard and exotic metal sub-components, including:
Niobium
Kovar
Copper
Stainless Steel
Invar
Titanium
Inconel
Our use of active brazing alloy (ABAs) is equally broad, with metals such as:
Nickel
Silver
Gold
Palladium
Copper
Zirconium
Value-Added Services
One of the most challenging tasks for any project manager is sourcing all of the components needed for a project. That’s where Sigma Advanced comes in. Deep relationships within the advanced material community offer us a unique opportunity to call upon our colleagues for additional services or consultative guidance when needed.
Our ability to multi-source allows us to create an integrative solution that turns your design from vision to realization in one single order rather than managing a host of disjointed and unrelated suppliers. Through our impressive network of top-tier, US-based supplier partners, we seek out the raw and finished good materials needed to complete your design.
The full BOM is managed through a single quote and invoice, making your buying experience faster, easier, and with far less paperwork to juggle. We are able to quote most projects part-complete – from ceramics and braze alloy components to full assembly kits. Our goal is always to finding the best quality, delivery time, and price for materials to provide you the highest possible value for your project. Our sourcing process involves procuring quotes from as many as four partners for a single component. We have a deep network of trusted partners and suppliers throughout the United States.

Looking for BYOC (Bring Your Own Components)? Our clients are absolutely encouraged to source their own certified bare components and share them with us for functional finishing and joining. Our unique agile approach allows us to flow our operational and functional steps in a bespoke manner to meet our clients’ needs.
When sending parts to us for services, we recommend partnering with an established manufacturer that stands behind their materials with certification and proof of origin. Want to order and manage your own development process but not sure which suppliers you can trust? Sigma Advanced Materials can recommend a great partner in the United States to provide exactly what you need.
