Alloy 4047 Aluminum Welding Rods Wire Strong Versatility For
Aluminum Alloy Welding
Alloy 4047 (commonly referred to as "718 aluminum” or AlSi12) is an
aluminum filler metal which contains approximately 12% silicon .
This alloy is commonly used not only in MIG or TIG applications ,
but also as a general purpose brazing alloy providing a
free-flowing filler metal and good corrosion resistance . 4047
aluminum filler rod is recommended for welding or brazing aluminum
alloy : 1060 , 1350 , 3003 , 3004 , 3005 , 5005 , 5050 , 6053 ,
6061 , 6951 , 7005 , and cast alloys 710.0 and 711.0. ER4047
aluminum welding rods has an approximate melting range of
1070-1080F and the post anodizing color tint is grayish-black .

The relevant knowledge
Every successful braze joint starts with a clean surface. Dirt,
grease, oil, scale and other contaminates inhibit capillary action,
and as such are a barrier to sound braze joints.
It is a common misconception that brazing fluxes and atmospheres
can clean surfaces. While this is true to some extent, this is not
their intended use and cannot be used in place of actual cleaning
processes. Fluxes and atmospheres will penetrate thin oxide layers.
remove oxide surface layers, and prevent the formation of oxides
Fluxes and atmospheres can also reduce surface tension of brazing
filler metals and form a protective cover over solidifying alloys
in brazed joints. However, fluxes and atmospheres alone are
ineffective in preparing surfaces for brazing.
Surface preparation can be divided into two categories – surface
treatments and cleaning. Cleaning removes contamination preventing
braze alloy from flowing and properly wetting. Surface treatments
enhance wetting and help alloy adhere to surfaces.
