The specific demands made on welded constructions require the application of the most suitable alloy. Pure aluminum and the Al-Mn alloy are still in use for the construction of containers and chemical appliances owing to their favorable prices and good corrosion resistance, wherever the demands made on the mechanical resistance are not excessive. Typical alloys for the manufacture of vessels and containers, and indeed as welding materials, are the non-heat-treatable alloys Al-Mg or Al-Mg-Mn, which still have a medium resistance in the soft state.
