4043 ALUMINIUM MIG WIRE – 0.8MM 0.5KG SPOOL
A good quality Aluminium alloy with 5% silicon giving excellent flow characteristics and penetration. Precision layer-wound for positive uninterrupted feeding. Suitable for use in gas-shielded MIG welding on both semi-automated and fully automated systems.
Suitable for most grades of Aluminium, but not suitable for marine grade or when post process anodising is going to be done.
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’ aluminiums. 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.
