Generally, brazing of the various aluminium alloys is restricted by the available filler alloys which are based on the binary system Al - Si. Alloys of type 2xxx and 7xxx are, therefore, not brazeable as their solidus/liquidus temperature are too low for the filler metals.
Sentes-BIR introduces new filler metal for brazing aluminium to aluminium and aluminium to copper with non-corros ive flux homogeniously mixed. No extra flux is required while brazing. Learn more 1001 COMP about flux and filler metal composite brazing rods and rings.

1001 Free-flowing, most fluid of aluminium filler metals. General purpose filler metal, can be used with brazeable aluminiums in all types of brazing. For joining aluminium and its alloys. Can be used for joining aluminium and titanium to dissimilar metals; the risk of galvanic corrosion then has to be considered. Excellent corrosion resistance when joining aluminium metals. Usable for both flame and furnace brazing. 10002, 10004 Zinc based general purpose filler metals for low temperature brazing/soldering of aluminium with a torch. ZnAl2 and ZnAl4 alloys. 10015, 10022 Higher corrosion resistance compared 10002 and 10004. ZnAl15 and ZnAl22 alloys.
