Key Features
● It is suitable for welding category of 6xxx aluminium alloys that heat treatment can be applied.
● Since it is not sensitive to heat crack it could be used for welding wrought aluminum alloy or cast aluminum alloy that Si is not more than 7%. Also brazing welding could be applied.
● But it is not suitable for welding aluminium magnesium alloy (category of 5xxx aluminium magnesium alloy) and it is not suitable for anodizing of electrical application.
● It is widely used for welding aluminium alloy structures of ships, locomotives & carriages, motor vehicles, containers, sports apparatus, furniture as well as industries of chemical, foodstuff and machelloning, etc.
