Aluminum welding wire alloy

A specialized solid filler material based on AlMg or AlSi alloys for joining lightweight materials via MIG and TIG processes.

Aluminum filler materials mainly come as AlMg or AlSi alloys. They make the weld pool flow calmly and prevent porosity in the seam. Which alloy you use depends on the base material – AlMg for AlMg sheets, AlSi more for castings or when good flow is needed. If you pick the wrong alloy, you get cracks or a weak seam. So: first check the base material, then choose the right wire or rod and work cleanly.
