Magnesium AZ31B

This material is a unique magnesium alloy with notable properties like corrosion resistance, heat treatment, and welding. Its corrosion resistance is commendable, owing to the presence of zinc, although it requires protection in aggressive environments. Heat treatment can enhance its mechanical properties, making it less brittle and more ductile through quenching above 300°C, and increasing its ductility and toughness with annealing before quenching. Magnesium AZ31B can be welded using TIG or laser welding methods, but proper surface cleaning before soldering is important for optimal results.

AZ31B has good machinability and can be easily cut, drilled, and shaped using standard machining processes. When machining AZ31B, we use machines with high spindle speeds and low feed rates. Magnesium alloys are softer than many other metals, so higher spindle speeds can help prevent work hardening and extend tool life. Magnesium can produce flammable fine chips, and the dust can be explosive. DEK has adequate ventilation and dust collection systems in place. We ensure the machining area is well-maintained and free of potential ignition sources.
