Brazing with 4047 or "brazing" with one of the low temp Zn alloys?
The product form will effect what alloys are available i.e. if buying barstock or extrusions you generally don't get much of a choice, typically a 6xxx series or a 6xxx series.
Avoid high magnesium alloys (most of the 5xxx series) and make the choice based on what you're doing i.e. the softer alloys (1xxx, 3xxx series) don't machine well but 6082 does. 6082 isn't very formable if you need to bend/shape it while 1050 and 3103 are very soft and formable

Thanks for the reply i use sif no16 brazing rods for my aluminium brazing. I cant get on with the lom temp stuff thats about. Most of the parts i need to make are out of hex bar as they are nuts for banjo bolts. so they are just drill & tap then brazed on. Other stuff i need to make are at least 10mm thick x 25mm x45mm & have 2 tapped holes in. No bending involved .
