Electrical Contacts
Silver laminates and bimetals for electrical contacts
Electrical contacts are key components in switching and power distribution systems, where maximum reliability is required over time, even under intensive operating conditions.
To ensure high performance, materials must combine excellent electrical conductivity, arc resistance and dimensional stability.
Pietro Galliani develops and manufactures thin laminates in silver, copper and Ag/Cu bimetals, designed for high-performance electrical contact applications.
Key applications
Data Centers & Power Infrastructure
The expansion of data centers is driving a strong increase in contactors, relays and power distribution systems. Silver-based laminates are used to ensure high conductivity and reliability in switching applications.
AI & High-Performance Computing
AI applications require high power density electrical systems, with an increasing number of connections and components. Thin laminates ensure precision, consistency and stable performance.
Automotive & E-Mobility
In automotive electrical systems, especially in electric vehicles, contact materials must ensure arc resistance and long-term durability. Ag/Cu bimetals provide an optimal balance between performance and cost.
