ESAB can now offer three types of aluminium MMA electrodes - OK 96.20, OK 96.40 and OK 96.50.
OK 96.20 is aluminium alloyed with a nominal 1 per cent manganese addition, usually used for the welding of rolled weldable aluminium magnesium and aluminium manganese alloys.
OK 96.40 is aluminium alloyed with nominally 5 per cent silicon. This is suitable for welding AlMnSi alloys such as AWS 6060/6063, 6005 and 6201. It can also be used to weld AlSi5Cu and AlSi7 cast materials.
OK 96.50 is aluminium alloyed with nominally 12 per cent silicon. This is primarily for welding cast aluminium alloys, but can also be used to weld rolled alloys and for joining cast to rolled alloys. If the base material is of unknown composition this electrode gives the best chance of success.
All three products are available from stock in 2.5mm and 3.2mm diameter in 4kg cartons. Each carton contains four packets. For more information about the aluminium MMA electrodes and other ESAB products, visit www.esab.co.uk.
