Magnesium Moves Into Vehicle Interior Structures
Vehicle weight targets have pushed carmakers toward magnesium for instrument panel beams, seat frames, steering wheel armatures, and display housings, all components previously made from steel stampings or injection moulded plastic. Magnesium castings weigh around a third less than equivalent aluminium and considerably less than steel, and hot chamber casting suits the alloy because its melting point sits low enough for the submerged gooseneck to survive. The machines needed are larger than typical zinc equipment and command higher prices. This is the only genuinely fast-growing application in an otherwise mature market.
Market Impact: Half the base exceeds 25 years
