SifAlumin No 15 4043A 3.2mm Aluminium TIG rods supplied in a 2.5kg pack.
An aluminium alloy with 5% silicon, offering excellent flow characteristics and penetration. Suitable for welding duralumin cast (LM25) and wrought alloys 6063 (H9), 6061 (H20) and 6082 (H30). Weld will discolour if anodised. Can be used TIG or in Oxy Acetylene. If used in Oxy Acetylene, use Sif No. 36 Aluminium brazing and welding flux.
Suitable for welding duralumin, cast and wrought alloys 6063 (H9), 6061 (H20) and 6082(H30), as well as other ‘4 series’ aluminium’s. The resulting weld will discolour if anodised. Pre-heating up to 120ºC may be necessary, subject to material size and thickness. Wire brushing between passes is recommended, to remove build up of surface oxides.
Ensure that the parent metal surface is cleaned and fully degreased prior to welding. Clean joints with a stainless steel brush.
Shielding Gas: Argon, Argon/Helium
