Lincoln suggests that if you have a need to design something of high strength aluminum look to a 5000 series high magnesium alloy instead of a 2000 or 7000 series. The 5000 series grades of aluminium are non heat-treatable alloys.

All of these alloys are weldable and much less crack-sensitive than 6061.
Welding 5000 series aluminum. Care must be exercised if welding a 1xxx series pure Aluminum base alloy with a 4xxx series Aluminum Silicon filler alloy to prevent a weld metal chemistry mixture within this crack sensitive range. A family of high-strength sheet and plate alloys. In fact they can be welded autogenously without adding filler metal using gas tungsten arc welding GTAWA.
As can be seen from the chart copper in aluminum alloys Al-Cu exhibits a. 5000 series aluminium is alloyed with magnesium is readily weldable and used in a wide variety of applications including pressurised vessels buildings and automotive. These are moderate-to high-strength non-heat-treatable alloys that are readily weldable and have excellent resistance to corrosion even in marine applications.
Magnesium is one of the most effective and widely used alloying elements for aluminum and is the principal element in the 5000 series alloys. The 5xxx series alloys in particular have excellent weldability. Magnesium is the main element used in the composition of the 5000 series grades of aluminium.
7010 and 7050 and most of the 2xxx series are not recommended for fusion welding because they are prone to liquation and solidification cracking. A good choice for 5000-series aluminum alloys is 5356 welding wire while 2319 wire is suited for 2000 series alloys. 5000 Series aluminum is mixed with magnesium different than manganese and has both a high tensile strength and formability.
1000 series or 5000 series etc. 6000 series aluminum alloys are. These wires produce the best color match with the alloys because they possess lower silicon content maintaining a silver anodized color that blends in well rather than a black color that is obvious and unattractive.
The 5000 Series Alloys are also very ductile and exhibit 30-40 weld elongation when welded with 5000 Series. The 5356 wire has become the most commonly used of all aluminum filler alloys because of its good strength and feedability when used as a MIG electrode wire. Welding 5XXX-series aluminum alloys a shielding-gas mixture combining argon with helium - 75 percent helium maximum - will minimize the formation of magnesium oxide.
The alloy is not suitable for use in elevated temperature service. High strength alloys eg. In addition the 5000 series loses far less strength when subjected to the heat associated with traditional welding processes minimizing the weak link that is often associated with welding.
The second digit represents the modification of the specific alloy within the series. In addition the 5083 aluminum sheet is also an alloy for welding structure in series 5000 aluminum which is suitable for welding structures vehicles low temperature vessels and pressure vessels. X1xx represents the first modification to the specified alloy while x2xx represents the second modification.
Click on an image below to view our grades. The first digit of the series indicates the principal alloying element added to the aluminium alloy and is used to describe the series ie. The 5000 series alloys are weldable and will produce the best results.
The Invision 352 MPa used by Greenheck welders features built-in Pulsed MIG programs for common 4000 and 5000 series aluminum wires ranging in diameter from 035 in to 116 in as well as many of the other alloys steel stainless steel silicon bronze copper nickel found in their products. These alloys are used primarily for structural applications in sheet or plate metals -- all 5000 series alloys are weldable 6000 series. Among the aluminum alloys used for automotive body applications the 5000-series alloys have higher weldability than the 6000-series alloys.
Aluminum magnesium and silicon. The 3 most popular commercial grades in this category are 5083 5754 5251. Hence it is widely used in fabrication such.
Taber Extrusions is considered the industry leader for specialty products including 5000 series extrusions for use in many major military programs. The technique of Friction Stir Welding is particularly suited to aluminium. Select an aluminum filler wire that has a melting temperature similar to the base material.
The use of 5000 series has several advantages as well. The 5000-series alloys can be welded with or without any filler material while the 6000-series alloys need filler material to prevent shrinkage cracking generated during the solidification of the liquid weld pool. The 4000 Series aluminum is often used as filler material for welding and brazing.
5000 series aluminum alloys are readily welded with 5356 filler metal. Non-heat treatable aluminum alloys exhibit excellent weld ductility when using like filler alloys. Highest ductility on the order of 60 elongation is observed with relatively pure aluminum alloys.
However with stronger alloys such as 5083 5183 or 5556 filler metals should be used. The temper is achieved by the plate being fully annealed and then rolled to the required. Most alloys in this series are either welding or brazing filler materials 5000 series.
Its designed to weld 5000 series.
