Indium

What Indium does

Indium Corporation, founded in 1934 and headquartered in Utica, New York, is a privately held, family-owned (Macartney family) materials science company that refines, smelts, manufactures and supplies advanced materials to the global electronics, semiconductor packaging, power electronics and solar value chains. Its core products span solder-based interconnect materials (pastes, preforms, bar, wire, spheres, ribbon/foil, fluxes), thermal interface materials (including the pioneer high-volume liquid metal TIM line), sintering materials (silver and copper sinter pastes under the InFORCE brand), specialty metals (indium, gallium, germanium, tin) and reclaimed/recycled feedstocks, complemented by a suite of proprietary technologies such as Durafuse, FAST (Formic Acid Soldering Technologies), Avoid the Void, Rel-ion, InFORMS, AuLTRA and NanoFoil. The company serves 20 essential markets including power electronics, PCB assembly/EMS, semiconductor packaging, high-performance computing/AI, automotive/EV, 5G, LED and defense-critical minerals.

The business operates a sales-led, engineer-to-engineer GTM model with regional direct sales and technical support teams across three geographic zones (Americas, Asia Pacific, EMEA), supported by an e-commerce storefront (buy.solder.com) for select SMB products. Pricing is quote-based, confidential and structured around multi-year enterprise contracts, with revenue diversified across hardware product sales, metals/compound reclaim and recycle services, and embedded technical support/engineering services. With 1,400+ employees and 16 facilities worldwide, Indium Corporation is a scale specialty materials supplier whose recent strategic posture — anchored by DOE TRACE-Ga funding, the Rio Tinto Quebec gallium partnership, the Metallium 10-year recycled-metals offtake, and the Ames National Laboratory AI-driven extraction collaboration — has shifted from pure materials supply toward a vertically integrated critical-minerals position targeting the US semiconductor supply chain.

Partnerships

Five partnerships are on record, tiered core and minor.

• Ames National LaboratorycoreStrategic or Co-development Partner · 3 June 2026Indium Corporation and Ames National Laboratory signed a research collaboration to develop domestic U.S. production of gallium, a critical semiconductor and electronics material currently imported almost entirely from abroad. The partnership leverages Ames Lab's AI-driven robotic experimentation capabilities to extract gallium as a high-value byproduct from aluminum refining waste, with the goal of building a complete domestic supply chain where none currently exists. The project is part of the DOE's TRACE-Ga initiative and aims to compress traditional 10-20 year materials development timelines to just 2-3 years.
• SEMI Advanced Packaging and Heterogeneous Integration (APHI) Technology CoalitionminorStrategic or Co-development Partner · 16 April 2026Indium Corporation is a member of the SEMI APHI Technology Coalition, which is positioned as the body facilitating cross-vendor collaboration through shared standards, research frameworks, and interoperability models for advanced packaging. Member companies contribute technical expertise on hybrid bonding and thermal interface materials.
• Metallium Limited / Flash Metals USA Inc.coreChannel Partner/ Reseller/ Distributor · 31 March 2026Metallium Limited's U.S. subsidiary, Flash Metals USA Inc., entered a 10-year off-take agreement with Indium Corporation to supply recycled gallium, germanium, and indium recovered using Flash Joule Heating technology from electronic waste. The deal provides formula-based pricing with auto-renewal options, long-term demand certainty for Flash Metals' urban mining operations, and supports US semiconductor supply chains with a faster alternative to primary mining.
• Rio TintocoreStrategic or Co-development Partner · 1 May 2025Indium Corporation partnered with Rio Tinto to extract primary gallium from Rio Tinto's alumina refining process in Quebec. First gallium was successfully produced in May 2025. The project includes construction of a pilot plant at Rio Tinto's Complexe Jonquière in Saguenay, with operations expected to begin in 2027, potentially producing 40 tonnes of gallium annually. Government of Canada has conditionally approved a C$18.95 million contribution under the Global Partnerships Initiative.
• ElementUSA MineralsminorStrategic or Co-development PartnerElementUSA Minerals is pursuing a $30 million DoD-funded Louisiana red mud processing collaboration for critical mineral extraction. The partnership is referenced in connection with Metallium's e-waste recycling expansion and broader US critical minerals supply chain initiatives in which Indium Corporation participates.
