BRAZING APPLICATIONS

C28 Aluminium Bronze MIG Brazing Wire finds widespread applications across diverse industries, owing to its unique combination of properties:

  • Marine and Offshore: In the maritime industry, where components are continuously exposed to saltwater and corrosive environments. C28 MIG Brazing Wire is a popular choice for joining shipbuilding components, offshore structures, and marine equipment.
  • Chemical and Petrochemical: The alloy’s superior corrosion resistance makes it ideal for the construction and repair of chemical processing equipment. Where exposure to aggressive chemicals is a constant concern.
  • Aerospace: C28 is well-suited for brazing aerospace components that require high strength, wear resistance, and resistance to atmospheric corrosion.
  • Hydraulic and Pneumatic Systems: C28 MIG Brazing Wire is used to fabricate joints in hydraulic and pneumatic systems, where reliability and leak-free connections are paramount.
  • Electrical and Electronic: The alloy’s excellent thermal conductivity makes it suitable for brazing electrical connectors and components that require efficient heat dissipation.
Brazing Technique and Best Practices

Moreover for optimal results with C28 Aluminium Bronze Brazing Wire, follow best practices and proper brazing techniques. See the following points for consideration -:

  • Surface Preparation: Thoroughly clean and degrease the joint surfaces to ensure proper wetting and adhesion of the filler metal.
  • Welding Parameters: Follow the manufacturer’s guidelines for welding parameters such as wire feed speed, voltage, and current to achieve the desired joint strength and quality.
  • Joint Design: Ensure appropriate joint design to minimize stress concentrations and maximize joint strength.
  • Post-Brazing Treatment: After brazing, it is essential to properly cool the joint to prevent residual stress and distortion.
CHEMICAL ANALYSIS

C28 Aluminium Bronze MIG Brazing Wire - Chemical Analysis

Brazing Vs Welding

The first key difference between brazing and welding is in brazing the base materials being joined are not melted, only the filler wire. Conversely in the welding process the base materials are penetrated. This reason being that during the welding process temperatures reached are higher than the base materials melting point.  In brazing it is the opposite, temperatures reached are lower than the melting point of the base materials thus avoiding penetration.

While there is no need to change the consumables in your torch when brazing or welding, there maybe a requirement for changing the settings on your welding machine e.g. voltage control, wire feed speed and/or gas cylinder settings in order to accommodate any differences encountered when using brazing filler material.

In Conclusion

Overall C28 Aluminium Bronze MIG Brazing Wire stands out as a versatile and reliable solution for creating strong, corrosion-resistant joints in a wide range of applications. With its high aluminium content and excellent mechanical properties, it offers superior performance. Consequently it’s a popular choice in critical industries such as marine, aerospace, and chemical processing. When used correctly with proper brazing techniques, C28 Aluminium Bronze MIG Brazing Wire ensures durable, robust, and long-lasting joints, meeting the demands of the most challenging environments and applications.
