For decades, gold and other precious metals have been the default answer in electronics and connector manufacturing. These metals have offered corrosion resistance, conductivity, and durability that no alternative could match, so manufacturers paid the price, built the dependency into their bills of materials, and moved on.
At the same time, the environmental cost of precious metal mining is drawing increasing scrutiny from regulators, customers, and corporate sustainability teams. For manufacturers who have built their production processes around these materials, the pressure is mounting. Reduce cost, reduce volatility exposure, reduce environmental impact and do it without touching product performance.
Xtalic was founded to solve exactly this kind of problem. Using a proprietary computational materials design platform, Xtalic engineers nanostructured alloys that deliver the performance of precious metals at a fraction of the precious metal content. The science is sophisticated, but the value proposition is straightforward: use less precious metals and get the same result, or better.

The Gold Reduction Benchmark
Gold is the most widely used precious metal in electronics manufacturing, prized for its corrosion resistance and stable contact performance. It is also one of the most expensive line items on bill of materials and one that scales directly with production volume. For high-volume manufacturers producing hundreds of millions of products annually, even a small reduction in gold consumption translates into significant cost savings.
XTRONIC® is Xtalic’s most commercially deployed precious metal reduction solution. It functions as a nanostructured nickel-tungsten barrier layer that replaces nickel in the connector plating stack, dramatically reducing the amount of gold needed to achieve equivalent corrosion and wear performance. The result is a gold reduction of up to 67%, not through compromise, but through smarter materials engineering that makes the gold work harder.
The scale of the impact is striking. Across global deployments on more than 45 customer-owned and third-party production lines, XTRONIC has enabled the savings of over 3.5 metric tons of gold, a figure that represents more than $485 million in precious metal cost avoided. It is a reality, validated across billions of connector units in the consumer electronics and datacomm markets.
A Smarter Alternative to Hard Gold
Not every application needs gold, but for many years, hard gold was the default finish because nothing else reliably matched its combination of wear resistance, corrosion protection, and low contact resistance. LUNA® changes that equation.
As a nanostructured silver-tungsten alloy, LUNA is engineered to match hard gold performance in many applications at a fraction of the cost. By engineering silver at the atomic scale, Xtalic dramatically improves on pure silver’s known weaknesses while preserving its excellent electrical conductivity. The result is an alloy that is 2–3 times harder than pure silver, thermally stable to 220°C, and capable of meeting the corrosion and durability requirements of a broad range of applications.
For manufacturers currently using hard gold in applications where LUNA qualifies, the cost reduction potential is substantial and the switch requires no significant changes to existing plating infrastructure. LUNA is also nickel-free and cyanide-free, making it particularly well suited for wearable devices and consumer electronics applications where both regulatory compliance and ESG commitments are increasingly important purchasing criteria.
Taking on Rhodium and Platinum
Rhodium and platinum occupy a unique position in the connector materials landscape, they are among the highest-performing contact finishes available, offering exceptional hardness, wear resistance, and thermal stability. They are also among the most expensive materials on the periodic table.
PALLEX® is a palladium nanostructured alloy, engineered to replace rhodium and platinum in waterproof connector applications. With hardness of 550–650 HV, thermal stability to 300°C, and proven wear and corrosion performance, PALLEX delivers the demanding results that rhodium and platinum users require at a lower cost that is far more predictable and manageable. It is also formulated to be nickel-free, making it compatible with wearables and consumer electronics applications where nickel restrictions are increasingly common.
What makes PALLEX particularly relevant in today’s market is Xtalic’s commitment to sustainable supply chains. PALLEX is available in low carbon footprint and ultra low carbon footprint versions that utilize recycled palladium, directly reducing the environmental burden of precious metal sourcing. For manufacturers navigating both cost pressure and ESG requirements, this positions PALLEX as a solution that addresses both simultaneously.
Supply Chain Resilience and the ESG Imperative
The manufacturers who are most vulnerable to precious metal price volatility are those who have built the deepest dependencies on them. When prices rise, they absorb it or pass it on, scramble for alternatives or their product roadmaps stall.
Reducing precious metal dependency is not just a cost optimization strategy, it is a supply chain risk management strategy. Every percentage point of gold eliminated from a connector stack is one fewer lever that commodity markets hold over a manufacturer’s cost structure and production continuity. The environmental and geopolitical risks embedded in precious metal supply chains are not abstract, they are operational realities.
Xtalic’s nanostructured alloys address this reality. By engineering alloys that require less precious metal to achieve the same performance, the company simultaneously reduces cost exposure and the environmental burden embedded in its customers’ supply chains. The $485 million in gold savings enabled by XTRONIC alone represents not just a financial benefit, but a meaningful reduction in the mining activity required to supply the global connector industry.
Performance Without the Precious Metal Premium
The connector and electronics industry has long accepted precious metal dependency as an unavoidable cost of performance. Xtalic’s portfolio of alloys demonstrates that this trade-off is no longer necessary. Across gold, palladium, rhodium, and platinum, Xtalic has engineered nanostructured alternatives that meet or exceed the performance of the materials they replace. This is validated in production, deployment at scale, and Xtalic’s ability to integrate into existing manufacturing lines without disruption.
The question for manufacturers is no longer whether high-performance alternatives to precious metals exist. The question is how much longer it makes sense to carry the cost, volatility, and environmental burden of precious metal dependency when a credible, proven path to reduction is available.
Xtalic’s team is ready to help manufacturers find that path, starting with a conversation about which products in your portfolio represent the greatest precious metal reduction opportunity.
