What it does

Designed to join aluminum to aluminum or aluminum to copper, AL822 uses a flux-core formulation that aids flow and helps reduce surface oxides during heating. The wire’s composition supports predictable wetting along the seam and neater, more consistent joints when used with compatible equipment and technique. The result is a versatile option for common aluminum alloys used in hobby builds and light fabrication.
