Description

Sifmig 328 MIG Brazing Wire – 0.8 mm x 4.0 Kg

Sifmig 328 is a specialized MIG brazing wire made up of 92/8 aluminium bronze. This wire is specifically designed for welding materials of a similar composition, copper alloys, and is particularly ideal for MIG Brazing dissimilar metal joints and maintenance applications. Its unique composition ensures a strong and durable weld, making it a preferred choice for various industries.

Key Features:

  • Aluminium Bronze Composition: Contains 92% copper and 8% aluminium, ensuring a robust and durable weld.
  • Corrosion Resistance: Provides resistance against corrosive media such as salt, making it ideal for marine applications.

Typical Applications:

The Sifmig 328 MIG Brazing Wire is primarily used for:

  • MIG Welding of Dissimilar Metals: Ideal for creating strong and durable joints in dissimilar metals.
  • Maintenance Applications: Suitable for maintenance tasks, ensuring longevity and durability of the components.
  • Surfacing: Recommended for surfacing metals to create wear-resistant surfaces, especially under relatively light loads.
  • Ship Building and Offshore Industries: Due to its corrosion resistance and strength.
  • Power Generation: For components that require a combination of strength and resistance to wear and tear.
  • Repair and Maintenance: Especially useful for maintaining car parts, tools, and bearings.
  • Chemical Industry: Due to its resistance to various chemicals and corrosive media.

Material to be Welded

Can be used on aluminium bronze alloys: CuAl8 Fe3, CuAl10 FeMn2, CuAl9 Mn9 and cast aluminium bronzes G-CuAl8, G-CuAl10Ni.

A small amount of pre-heat/warming may be required prior to brazing, depending on the material thickness and  aluminium content.

For optimal results, it’s essential to ensure that the areas to be welded are clean and free from contaminants. Depending on the material thickness and aluminium content, a small amount of pre-heating or warming may be required prior to brazing. Proper pre-heating techniques should be employed, especially when working with materials with high aluminium content.
