Working with EN AW-5083 Cast Plate-STD
Is EN AW-5083 Cast Plate easy to machine?
Machines predictably but gummy: use sharp polished-flute carbide, high rake, 300–900 m/min, generous flood or MQL coolant to avoid built-up edge and stringy chips.
Can EN AW-5083 Cast Plate be welded?
Excellent with GMAW/GTAW using ER5183 or ER5356 filler; no preheat above 120 °C, keep interpass low and avoid post-weld exposure over 65 °C to prevent sensitisation.
Can EN AW-5083 Cast Plate be formed, bent or molded?
Cast plate is a machining stock — avoid bending or deep drawing; hot forming above 250 °C only, and any cold work should be followed by stress relief to restore flatness.
What surface finishes work on EN AW-5083 Cast Plate?
Responds well to hard and clear sulphuric anodize (cast structure may streak decorative films); paints and chromate-free conversion coatings adhere well; not brazeable due to high Mg.
EN AW-5083 Cast Plate chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
