4047 TIG Filler Wire

Product Details

4047 TIG Filler Wire

4047 TIG Filler Wire is an aluminium-silicon welding rod designed for TIG (GTAW) welding of aluminium alloys. It features a high silicon content, typically around 12%, which improves weld fluidity, reduces shrinkage, and minimises hot cracking during welding. 

Originally developed as a brazing alloy, 4047 filler wire has a low melting point and narrow freezing range, allowing smooth weld pool control and clean, consistent welds. It is suitable for precision aluminium welding and applications where minimal distortion and strong, corrosion-resistant welds are required.
