Brazing Rings and Preforms
Customized solutions for precise, efficient, and automated brazing processes
Pietro Galliani manufactures brazing rings and preforms for industrial applications requiring precision, repeatability, and process control.
Manufactured from silver-based brazing alloys, copper-phosphorus alloys, ETP-OF and DHP copper, copper-phosphorus-silver alloys, and other special alloys, our rings and preforms are the ideal solution for companies looking to optimize assembly operations, reduce material waste, and ensure consistent brazed joint quality.
Thanks to our dedicated production facility in Milan, Italy, we can supply both standard components and fully customized solutions tailored to customer specifications.
Brazing Rings
Brazing rings are calibrated preforms available in a wide range of configurations, including closed rings, open rings, overlapped rings, tube-mounted rings, half-rings (crescent shapes), and multi-turn spiral rings.
The use of brazing rings allows customers to:
- Ensure a uniform distribution of filler metal
- Improve joint quality and process repeatability
- Reduce alloy waste
- Simplify assembly operations
- Increase productivity in automated and semi-automated production lines
Thanks to their practicality and reliability, brazing rings are widely used in industrial applications where high precision and consistent production quality are required.
Custom Brazing Preforms
Brazing preforms are custom-made components designed to perfectly match the geometry of the parts being assembled.
They can be manufactured in various shapes, including:
- Discs
- Washers
- Plates
- Stamped preforms
- Custom-designed shapes according to customer drawings
The ability to customize shape, dimensions, and alloy composition helps optimize production processes while ensuring more reliable and controlled brazed joints.
Preforms are particularly suitable for high-volume automated brazing operations, where precise alloy dosing is essential to achieving consistent product quality.
