5183 is a precision layer wound aluminium wire alloyed with Mg, Mn and Cr. It is recommended for welding Al/Mg material of the 5083 type in the annealed condition, particularly for low temperature applications where good ductility and toughness are required, ie cryogenic plant. It may also be used for welding medium strength Al/Zn/Mg alloys of the 7020 type and joining 5083 alloy to 5456 alloy.
