Materials and Solutions for Data Centers and Electrification
Advanced materials for power connections and thermal management
The growth of data centers, artificial intelligence, energy storage systems and electrical infrastructure is increasing the need for components that can handle higher power levels while ensuring operational continuity, energy efficiency and long-term reliability.
Pietro Galliani develops and manufactures data center materials and solutions for electrical infrastructure: brazing filler metals, preforms, precision metal foils and composite materials for electrical connections, protection systems, cooling components and thermal management solutions.
By combining the expertise of its Brazing and Industrial Foils divisions, Pietro Galliani can support customers from material selection and format definition through to the development of customized solutions for manual or automated manufacturing processes.
Electrical and thermal reliability for increasingly demanding infrastructure
In data centers and electrical infrastructure, even a single component can affect the safety and continuity of the entire system.
Increasing power density creates new requirements in terms of:
Selecting the right alloy, metal, thickness, format and joining technology is therefore essential to achieve consistent performance and reduce the risk of failure.

Brazing division
Brazing solutions
Brazing filler metals for reliable and repeatable joints
The Brazing division manufactures brazing and soldering filler metals for electrical, thermal and mechanical joints.
Depending on the base materials, process temperature and required performance, the product range includes:
- cadmium-free silver-based brazing alloys
- copper-phosphorus alloys
- silver-copper-phosphorus alloys
- copper- and brass-based alloys
- aluminium brazing alloys
- tin-based soft soldering alloys
- solutions developed for specific applications
The alloys can be supplied in different forms to suit the component and manufacturing process:
- wire
- bare or flux-coated rods
- strips and foils
- rings
- preforms
- powders and pastes
- custom-made shapes manufactured to drawing
Rings and preforms for automated processes
Rings and preforms make it possible to place a controlled and repeatable amount of filler metal directly at the joint.
They can help to:
- improve process repeatability
- control the volume of filler metal used
- reduce overdosing and waste
- facilitate automation
- limit subsequent cleaning operations
- reduce the effective cost per joint
- increase consistency in series production
The geometry of each preform can be designed around the component, heating method and expected production volumes.

The GALFLO range includes fluxes developed for different filler metals, base materials and brazing temperatures.
Available product lines include:
Flux selection should take into account the filler metal, base materials, heating method, joint geometry and overall process requirements.
GALFLO Eco Green solutions have also been developed in response to growing attention to operator safety and the reduction of substances carrying critical hazard classifications.
NanoTech for copper-phosphorus alloys
NanoTech technology is applied to copper-phosphorus alloys and is designed to improve filler-metal behaviour during brazing.
Depending on the application, it can provide:
- improved wettability
- more uniform flow
- reduced sparkling
- a cleaner and more controllable process
- greater stability in repetitive production
Industrial Foils division
Industrial Foils solutions
Precision metal foils for electrical components
The Industrial Foils division manufactures thin metal foils and precision strips for applications in which conductivity, dimensional tolerances and material consistency are essential.
The range includes:
Materials can be customized in terms of:
- composition
- thickness
- width
- temper and hardness
- tolerance
- surface roughness
- layer configuration
- supply format
Silver-copper bimetals for electrical protection and contacts
Ag/Cu bimetals make it possible to place silver only in the functional areas of the component, combining its electrical properties with the structural and economic contribution of copper.
Available configurations include:
These materials can be developed for fuse elements, contacts and other components used to manage and protect electrical current. The configuration can be engineered to optimize the distribution of precious metal in relation to the component’s function.

- heating
- electromagnetic shielding
- integration into circuits or multilayer components
Configurations may combine copper or aluminium with different polymer films selected according to the application and operating conditions.
From application to material
The final solution must be assessed against the base materials, geometry, operating conditions, manufacturing process and regulatory requirements of the application.
Engineering and co-development
A solution developed around the component
Not every application can be addressed with a standard product.
Pietro Galliani works with customers’ engineering and production teams to define the most suitable solution through:
Expertise in metallurgy, together with in-house casting, refining and metalworking capabilities, supports control of the material across the main stages of the manufacturing process and the development of customized solutions.
Quality, traceability and material control
Applications for electrical infrastructure and data centers require consistent performance and process control.
Pietro Galliani combines production and laboratory expertise to support:
- composition control
- verification of dimensional characteristics
- batch traceability
- metallurgical analysis

Frequently asked questions
Which Pietro Galliani products can be used in data center applications?
The range includes brazing filler metals, rings, preforms, fluxes, copper and silver strips, Ag/Cu bimetals and metal-polymer laminates. The appropriate choice depends on the component and on the required electrical, thermal or mechanical function.
Can Pietro Galliani develop materials to customer specifications?
Yes. Compositions, dimensions, tolerances, formats and customized configurations can be assessed on the basis of the customer’s drawing, manufacturing process and expected volumes.
Is it possible to request samples?
Yes. Following an initial technical assessment, a sample can be defined for testing by the customer.
Why use rings or preforms?
A controlled-dose form places a defined amount of filler metal at the joint, supporting process repeatability and automation while helping to limit overdosing and scrap.
What is the advantage of a silver-copper bimetal?
A bimetal combines the functional properties of silver with those of copper, placing the precious metal only in the areas of the component where it is required.
Can you recommend a filler metal or material directly?
We can provide a preliminary selection. The proposed solution must then be validated against all application parameters and through the necessary testing on the customer’s component and process.
