ESAB 4043 is one of the oldest and most widely used welding and brazing alloys. It can be classified as a general purpose type filler alloy.

The silicon additions result in improved fluidity to make the alloy a preferred choice by welders.

This alloy is less sensitive to weld cracking and produces brighter, almost smut free welds.

Alloy 4043 is one of the oldest and most widely used welding and brazing alloys and can be classified as a general purpose filler alloy. The silicon additions result in improved fluidity (wetting action) to make the alloy the preferred choice for welders.

The alloy is less sensitive to weld cracking and produces brighter, almost smut-free welds.

The alloy is non-heat treatable.

Alloy 4047 was originally developed as a brazing alloy to take advantage of its low melting point and narrow freezing range.

In addition, it has a higher silicon content than 4043, which provides an increased fluidity and reduced shrinkage. The alloy produces bright and almost smut free welds.

Hot cracking is significantly reduced when using 4047 as a filler alloy.

The alloy may be used in applications of sustained elevated temperatures.

The alloy is non-heat treatable.

Alloy 5356 was developed to provide the highest strengths possible in the as-welded condition of alloy AA5083 and other similar high magnesium alloys. The more common filler alloy 5356 will typically fail to meet the as-welded tensile specification requirements of alloy 5083.

The alloy is typically utilized in applications where high strengths, high fracture toughness for impact resistance and exposure to corrosive elements are important.

The alloy is not recommended for elevated temperature service applications.

The alloy is non-heat treatable.

Alloy 5353 is the most widely used welding alloy and can be classified as a general purpose type filler alloy.

Alloy 5356 is typically chosen because of its relatively high shear strength. Any 5XXX alloy base material, welded with 5356, with a weld pool chemistry greater than 3% Mg and service temperatures in excess of 650C are susceptible to stress corrosion cracking.

The alloy is not recommended for elevated temperature service applications.

The alloy is non-heat treatable.

Alloy 5554 is a solid aluminum wire with a typical 2.7% magnesium content. It is recommended for welding of aluminum-magnesium alloys like 5454.

Typical applications are chemical storage tanks, automotive components like wheels and frame sections.

The weld metal is not sensitive to stress corrosion cracking at elevated temperatures.

Alloy 5556 develops the highest as-welded strengths in fillet welds, nearly double that of 4043.

The 5XXX series of alloys offer an excellent combination of corrosion resistance, strength, toughness, workability and weldability. As a result, they are used in a wide variety of applications.

One characteristic of this series of alloys, however, is their susceptibility to stress corrosion cracking when the weld pool chemistry is greater than 3% Mg and there is exposure to prolonged temperature in excess of 650C. Special alloys and tempers are often required to overcome this problem.

The alloy is non-heat treatable.
