Welding wire for MIG welding of aluminium alloys.
Very appropriate for welding of heat treated aluminium (AA 6000-range).
The deposit is hardly susceptible to cracking when joining hardenable aluminium alloys.
For welding AlMg-alloys with a high Mg-content, using Lastifil 77 is recommended because of hardness and strength reasons.
The weld beads become darker when anodized.
Welding of AA6060; AA6082; AlMgSi0.5; AlMgSi0.7; AlMgSi1; AlMg1SiCu; G-AlSi7Mg; G-AlSi5Mg; G-AlSi6Cu4 and dissimilar aluminium alloys.
Use Teflon wire conductors and appropriate driving wheels on the wire feeder.
Preferably use a push-pull torch.
