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 â€˜4 seriesâ€™ 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.
