Mamer (Luxembourg), 19.05.2026 — The Plansee Group has announced that Plansee US Holding Corp. and Manhattan Five Partners LLC have entered into a definitive collaboration framework agreement outlining the formation of a joint venture to establish a strategic tungsten oxide stockpile in the United States.

For the CERATIZIT Group, this is a highly positive strategic milestone: it reinforces our long term positioning on supply chain security — resilient by design, recycling-driven, and anchored in an integrated value chain. It also strengthens the Western processing base that underpins our promise to customers: stability and reliability in an environment shaped by volatility and increasing traceability requirements.

The initiative is designed to ensure a secure supply of tungsten in the United States and reduce reliance on foreign sources for critical minerals. It combines Plansee’s industrial and technological leadership in tungsten oxide processing with Manhattan Five’s expertise in structuring, financing, and managing large-scale infrastructure and strategic asset platforms.

As part of the initiative, Plansee intends to expand production capacity for tungsten oxide at its U.S. facility in Towanda, Pennsylvania — Global Tungsten & Powders (GTP), a division of the CERATIZIT Group — to approximately 12,000 tons per year within a short timeframe. Initial deliveries are expected to start in 2026.

A significant portion of production will support a strategic tungsten oxide reserve intended to serve government, defense, and critical industry demand. Under the joint venture structure, Manhattan Five will oversee warehousing, logistics infrastructure, and long-term asset management, while Plansee will lead production expansion and supply.

Integration and control across the value chain

CERATIZIT’s supply security is built on a fully integrated tungsten value chain as part of the Plansee Group — from tungsten powder to finished tools — creating control over crucial steps and reducing exposure to short-term market fluctuations.

Within CERATIZIT, the GTP division plays a central role in this model. As our raw materials and powder division, GTP strengthens processing, recycling and traceability capabilities that support long-term stability for customers across key industrial sectors.

Recycling-driven supply as a strategic stability factor

CERATIZIT operates a recycling-driven supply chain with a ~90% tungsten recycling rate (FY 2024/25). This circular approach reduces dependence on primary raw materials and lowers the carbon footprint while strengthening long-term supply resilience. 

Responsible sourcing and transparent standards

CERATIZIT ensures raw materials are sourced responsibly and transparently through RMI conformant smelters and a strict Supplier Code of Conduct. This supports compliance and traceability expectations in customer supply chains.

What this means for CERATIZIT customers

For customers, the value is clear:

• Stronger Western processing base supporting long-term stability and planning reliability
• Resilience enabled by an integrated value chain and control of crucial steps
• Recycling-driven supply security supported by a ~90% tungsten recycling rate (FY 2024/25)
• Responsible sourcing and transparent standards through RMI-conformant smelters and a strict Supplier Code of Conduct

AUSTIN, TX, UNITED STATES -- Electroninks, the leader in metal complex inks for additive manufacturing and advanced semiconductor packaging, today announced the company’s new gold and silver nanoparticle inks from its UTDots portfolio, which will be commercially available through Sigma-Aldrich. The new product family includes six conductive ink formulations with a focus on green solvents and optimized for inkjet and aerosol jet deposition platforms, enabling high-performance additive manufacturing across applications ranging from wearable devices and biosensors to RF systems, EMI shielding, and advanced defense electronics.

The launch includes the following commercially available formulations:

• UTD-Ag-25IJ
• UTD-Ag-40IJ
• UTD-Ag-60PA
• UTD-Au-25IJ
• UTD-Au-40IJ
• UTD-Au-60IJ

As manufacturers increasingly shift toward digital fabrication methods, UT Dots’ nanoparticle inks are designed to provide the conductivity, process stability, and scalability required to move printed electronics beyond prototyping and into broader commercial deployment.

“The printed electronics market is moving rapidly toward higher-performance, digitally manufactured systems that demand both precision and scalability,” said Alex Didenko, engineer at Electroninks, managing the product development of the UTDots portfolio.. “Our new nanoparticle ink portfolio was developed to help engineers and manufacturers bridge that gap with materials capable of supporting everything from flexible consumer devices to highly demanding aerospace and defense applications.”

Engineered for Precision Across Modern Printing Platforms

The new ink portfolio is designed to support a broad range of additive manufacturing workflows and geometries. UT Dots’ inkjet-compatible formulations are optimized for stable and repeatable droplet formation, enabling fine-feature patterning with minimal variability across flexible and rigid substrates alike. The aerosol jet-compatible series extends those capabilities further, supporting conformal deposition on complex three-dimensional surfaces with feature widths below 200 microns.

This flexibility enables manufacturers to print conductive structures on everything from planar flexible circuits to curved integrated systems without sacrificing precision or consistency.

Near-Bulk Conductivity for High-Performance Applications

Following sintering, UT Dots’ silver nanoparticle inks achieve resistivity values between 3–10 microhm-centimeter, approaching the performance characteristics of bulk silver while maintaining compatibility with additive manufacturing processes.

The company’s gold nanoparticle formulations achieve conductivity levels within 2–7x of bulk gold and support photonic curing in the 500–550 nm wavelength range. This capability allows conductive structures to be processed on temperature-sensitive substrates that are incompatible with conventional high-temperature thermal curing methods.

These performance characteristics position the materials for demanding applications requiring high conductivity, low-profile form factors, and advanced integration flexibility.

Accelerating Innovation in Printed Biosensing

UT Dots’ gold nanoparticle formulations are also designed to support emerging biosensing and diagnostic applications. Gold’s inherent biocompatibility, oxidation resistance, and compatibility with thiol-based surface chemistry make the UTD-Au series particularly well suited for applications including:

• Enzymatic glucose sensors
• Immunoassay platforms
• DNA detection arrays
• Lab-on-chip microelectrode systems

By enabling mask-free additive fabrication through inkjet printing, the platform significantly shortens the design-to-prototype cycle compared to traditional lithography-based manufacturing methods. The result is faster iteration, reduced material waste, and improved development flexibility for researchers and medical device developers.

Designed for Commercial Scalability

Beyond laboratory development, UT Dots engineered the new ink platform to support long-term manufacturing scalability. The formulations are produced using standardized synthesis processes and strict quality-control methodologies designed to ensure strong batch-to-batch consistency. This allows manufacturers to maintain predictable electrical and processing performance as products transition from early-stage development into commercial production environments.

“As electronic microdevices continue maturing into broader application spaces, including medical devices and advanced sensors, material consistency and reliability become just as important as conductivity,” stated Melbs LeMieux, cofounder and president of Electroninks, UT Dots’ parent company. “We built this portfolio to support our continuous expansion of advanced materials to address new markets and customers.”

The new conductive ink portfolio is available immediately for customer evaluation and commercial integration. For more information on UT Dots products and solutions, please visit www.utdots.com.

WASHINGTON, DC -- The Printed Circuit Board Association of America celebrates the introduction of a crucial bill that will pave the way to reshore and restore America’s printed circuit board (PCB) industry.

"The challenge is that PCB production was offshored to heavily subsidized companies in Asia. This leaves American companies competing with countries,”said David Schild, executive director, PCBAA.

Over the past 30 years U.S. share of the world supply of PCBs shrunk from 30 percent to 4 percent because of offshoring. Congress is offering legislative solutions to reverse this trend.

Senators Ruben Gallego (D-AZ) and Jim Justice (R-WV) introduced S.4569, the Protecting Circuit Boards and Substrates Act, to incentivize domestic manufacturing of PCBs. The bill provides a 25% tax credit for the purchase or acquisition of American-made PCBs.

This bill is a companion to H.R. 3597, the Protecting Circuit Boards and Substrates Act which also calls for the tax credit and a $3 billion grant program for support of American PCB manufacturers.

“These two bills impact both national and economic security. Every semiconductor needs a PCB to function. The challenge is that PCB production and know how has been offshored to heavily subsidized industries in Asia. This leaves American companies with the impossible task of competing with countries”, said David Schild, Executive Director of PCBAA. “We must reshore and restore this industry to reduce the reliance of other nations at the end of long and vulnerable supply chains.”

The American semiconductor industry is expanding because smart industrial policy has incentivized private investment. This legislation is the natural next step in an American manufacturing renaissance.
