Description and applications*
* Illustrative, not-exhaustive list
This silicon-aluminium filler material is one of the oldest and most widely used welding alloys. It can be classified as a general purpose type filler alloy.
Silicon with this alloy gives improved wetting action yielding a less crack sensitive bright weld bead.
Excellent when aesthetics are of importance. Not recommended for material to be anodized.
This grade may be used for:
• applications in about all the industrial manufacturing sectors, such as theautomotive industry, the production of mobile equipments, the ship building sector, etc.
