\"Magnesium<\/figure>\n\n

Short answer:<\/strong> Choose magnesium<\/strong> when mass, specific strength, and damping matter more than absolute corrosion robustness and piece-price; choose aluminium<\/strong> when you need broader process windows, familiar supply chains, and typically lower melt-handling risk. Many programs stay aluminum; magnesium wins when the weight budget is real.<\/p>\n\n

Both alloys are commonly produced by hogedrukgieten<\/strong>. Differences show up in melt handling, die thermal design, and secondary finishing\u2014not in \u201cwhether HPDC exists.\u201d<\/p>\n
