A general purpose aluminium rod containing 5% magnesium that has excellent corrosion resistance and high strength.Suitable for welding magnesium bearing aluminium, alloys such as 5251 (N4), 5154 (N5), 5454 (N51), and also heat treatable alloys 6063 (H9), 6061 (H20) and 6082 (H30). Can be used in TIG or oxy/acetylene. If used in oxy/acetylene, use with our Sif No.36 aluminium brazing and welding flux.
Applications
Can be used to weld components which are to be subsequently anodised
Pre-heating up to 1200C may be necessary, subject to material size and thickness
Wire brushing between passes is recommended to ensure removal of surface oxide build up
Ensure that parent metal surface is cleaned and fully degreased prior to welding
