Al-Mg-Sc Aluminium Metal Powder
Al-Mg-Sc is a corrosion resistant Al-Mg-Sc alloy with improved performance in heat treated state. The parts or samples do not require solution treatment followed by quenching. High properties are achieved
after conventional annealing. Sc concentration was adjusted so as to provide an optimal high tensile characteristics to price ratio. Parts can be machined, welded, polished, coated or treated otherwise like
conventional Al-Mg products.
