LUNA®
LUNA® is a nanostructured silver alloy designed to replace gold in connectors and overcome the limitations of traditional materials. Engineered to deliver gold-level performance, LUNA combines durability, thermal stability, and corrosion resistance to deliver the same performance as hard gold without the volatile market costs associated with precious metals. In addition to exceptional wear durability, LUNA delivers superior high-temperature stability compared to conventional silver solutions.
LUNA’s nanocrystalline structure enhances hardness and stability, helping connectors maintain low contact resistance and long-term reliability across repeated mating cycles. When integrated into a complete plating stack, LUNA enables manufacturers to reduce precious metal content without sacrificing performance. The result is a scalable, cost-effective solution for consumer electronics, data communications, and other demanding electrical interconnect applications.

Thermal Stability: Operates safely up to 220°C
Enhanced Hardness: 2-3X hardness of pure silver, reducing friction force and extended durability
Conductivity: As conductive as hard gold and boost ampacity in connector applications
Corrosion Resistance: Built to withstand harsh environmental conditions, maintaining stable properties over time
Arc Erosion resistance: Suitable for low power hot make/break
LUNA is 2 times harder than pure silver after aging 2,000 hours at high temperatures.
The stable nanostructure engineered into LUNA silver alloy ensures its consistent thermal performance – delivering additional reliability, safety and performance to high-reliability applications. The figure shows the characteristic nanometer-scale grain size of LUNA after plating, compared to the much larger micrometer scale grain size of silver. Upon heating for 24 hours, LUNA demonstrates thermal stability with no apparent grain growth. By comparison, traditional silver shows significant grain coarsening and softening, an irreversible change to the structure, leading to a loss in performance.
Reduced Costs: Minimizes reliance on precious metals like gold, offering a sustainable alternative
Sustainability: Low carbon footprint, cyanide-free and nickel-free
Improved Performance: Effective diffusion barrier, low and stable electrical contact resistance
Enhanced Reliability: Delivers consistent performance under extreme conditions, lowering maintenance and warranty costs
