EN ISO 18273 S Al 4043A (AlSi5)
BS: 2901 4043A, (NG21)
Melting Point 635°C
Ult Tensile Strength 120 N/mm²
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.
