Rings, Wire and Preforms

At SolPro Brazing, we recognise that in high-volume manufacturing, component consistency isn't just an advantage - it's a critical operational requirement. Standardising your alloy application is key to maintaining tight tolerances, eliminating material waste, and guaranteeing structural joint integrity.

Engineered preforms - including custom brazing rings, pre-cut wires, and tailored shapes - provide a clean, precise, and repeatable method to deliver the exact volume of filler metal needed for every single joint. This makes them the ideal solution for modern automated and semi-automated assembly lines, as well as complex manual operations.

Custom-Engineered for Your Industry

We manufacture high-purity brazing rings, wires, and preforms to meet exact dimensional and metallurgical specifications across a vast range of demanding sectors, including:

  • HVAC & Refrigeration: Leak-free, high-integrity joints for heat exchangers and pipework.

  • Automotive: Reliable, high-throughput components engineered for strict quality standards.

  • Tooling & Carbide Tipping: Precision placement for heavy-duty, high-wear applications.

  • Electrical Contacts & Assemblies: Consistent conductivity and joint strength for power components.

Whether you need standard stock dimensions or bespoke shapes engineered to your technical drawings, our expert team can support your production line from initial prototype to full-scale manufacturing.

RINGS

Why settle for the inconsistency of hand-fed rods? SolPro’s preformed rings enable your team to achieve a perfect 360-degree seal every time.  By incorporating our rings into your workflow, you can significantly reduce material waste and post-braze cleanup, while virtually eliminating the risk of "starved" joints. 

Our rings deliver a precise, pre-measured volume of filler metal to every connection, eliminating the variables associated with manual brazing.

  • Materials offered include Silver and Copper Phosphorus brazing alloys with an extensive range of Copper and Aluminium alloys.
  • Our products come in various sizes and wire diameters, with options for single or multi-turn configurations.
  • Customised packaging to meet individual customer requirements.

BRAZING WIRE

For flexible, precise applications, brazing wire deliver reliability. Manufactured to top metallurgical standards, our wires offer smooth and consistent flow with exceptional wetting across various temperatures.

Available in multiple diameters and alloys, our wires are perfect for technicians to ensure strong bonds in any environment.

We are able to draw down wires to 0.5mm diameter and can supply in coil form or on spools depending on the requirement.

PREFORMS

Streamline your high-volume production with SolPro’s custom preforms. Our preforms are available in various shapes like washers, slugs, and multi-turn coils, and can be tailored to your specifications. 

By positioning the filler metal where it’s needed before heating, they integrate seamlessly with automated induction and furnace brazing systems. This precision reduces errors, minimises waste, and ensures every unit meets high standards.

We can produce a range of cut or stamped brazing preforms for a range of applications in various alloys.
