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.
