Description
Aluminium wires and rods for semi-automatic MIG and TIG welding in argon, helium or mixture Ar + H1 shielding, containing approx. 5% Mg and increased Mn content to increase strength. Intended for welding AlMg and AlMgSi alloys with high strength. The weld deposit is characterized by high resistance to seawater.
