Description
Sifalumin No 15 4043A Aluminium TIG Welding Rods – 1.6 mm x 1 Kg
Material to be Welded
- Suitable for welding duralumin, cast and wrought alloys 6063 (H9), 6061 (H20) and 6082(H30), as well as other 4 series aluminium.
- The resulting weld will discolour if anodised [If the finished article is to be anodised, use 1050A, or 5356].
- 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.
