AWS/ASME 5.3 E 4047
EN 573-3: E AlSi12
DIN 1732: EL-Al Si12
FEATURES & APPLICATIONS |
For arc welding aluminums alloyed with copper, silicon, and magnesium.
Also excellent for joining dissimilar grades of aluminum.
12% Silicon aluminum arc welding electrode with exclusive self lifting slag. Other aluminum grades such as Al 99, Al Mn, etc. are also available.
- Unique self lifting slag.
- Pure white long shelf life extruded flux coating outlasts conventional products in moisture resistance.
- Can be manufactured in a variety of custom colors.
- Available in hermetically sealed PURE ALUMINUM pull ring cans or vacuum packed foil bags for extended shelf life.
- Also available in TIG form as item code 6047, in MIG form as item code 7091 and as a bare torch brazing alloy as item code 2191.
