Aluminum tIG welding rod ER4047
ER4047 aluminum welding wire with 12% silicon content outperforms standard ER4043 wire, delivering exceptional flow characteristics and crack resistance. It is generally used for brazing aluminium sheets, for extrusions and castings.
Standards: AWS A5.10 ER4047
Approximate 12% silicon, which provides lower melting point and higher fluidity than ER4043
Minimize hot cracking and strengthen higher fillet weld shear strength.
Welds maintain integrity after surface treatment.(Visible color difference post-anodizing)
All-position capability (including vertical-down)
Shielding Gas: 100% Argon
Aerospace: Structural components, repair work
Transportation: Rail cars, ship superstructures
Industrial: Chemical tanks, nuclear components
Precision Fabrication: Bicycle frames, architectural elements
