    OK Autrod 5356 (formerly OK Autrod 18.15) is the most widely used welding alloy and can be classified as a general-purpose type filler alloy. OK Autrod 5356 is typically chosen because of its relatively high shear strength. The 5XXX alloy base material, welded with OK Autrod 5356, with a weld pool chemistry greater than 3% Mg and service temperatures over 65°C, is susceptible to stress corrosion cracking. The alloy is non-heat treatable.

    Welding current: DC(+)

    Mig 5356 FAQs

    Straight answers on choosing, feeding, storing and troubleshooting 5356 (aluminium-magnesium) MIG wire.

    When should I choose 5356 wire rather than 4043?icon-minus-redicon-plus-red

    5356 is an aluminium-magnesium filler. It gives a stronger weld than the aluminium-silicon 4043 and is the usual choice for structural work, for common alloys such as 6061 and for most 5000-series plate. It is also the better option if the part will be anodised afterwards.

    4043 is generally preferred where cracking resistance matters or the part sees elevated temperatures. Where the base alloy is specified in a drawing or code, follow the filler selection chart for that alloy and the job's service conditions.

    Will a 5356 weld match the colour of an anodised part?icon-minus-redicon-plus-red

    Usually it will be a much closer match than a silicon-bearing filler. The silicon in 4043 and 4047 normally leaves the weld dark grey after anodising, whereas the magnesium in 5356 lets the weld take the anodised finish in a similar colour to many common base alloys.

    The match is never perfect on every alloy, so if appearance matters, weld and anodise a test piece first. Tell the anodiser which filler was used.

    Why does my aluminium wire tangle or stop feeding, and how do I prevent it?icon-minus-redicon-plus-red

    Aluminium wire is soft, so it crushes and buckles in a feed path built for steel. The usual remedies are U-groove drive rolls with light pressure, a smooth plastic (such as PTFE) liner instead of a steel one, a clean, correctly sized contact tip made for aluminium, and a short, straight cable.

    If the feed path is long, a push-pull torch or a spool gun, which keeps the wire path short, often cures it. If the wire still tangles, check the liner, the tip bore and the roll pressure before changing the machine settings.

    How should I store a reel of 5356 wire?icon-minus-redicon-plus-red

    Keep the reel in its sealed original packaging until you need it and store it somewhere dry and at an even temperature. Aluminium wire picks up moisture easily, and moisture on the surface is a leading cause of porosity in the weld.

    Once on the machine, keep the reel covered and put unused wire back into its bag. If a cold reel is brought into a warm, humid workshop, let it warm up before opening it so that condensation does not form. Handle the wire with clean gloves.
