Frequently Asked Questions
Was sind der limitations von magnesium alloys?
(1) Hexagonal schließen-packed (HCP) crystal structure limits kalt formability — meiste forming müssen sein done warm (200-300°C). (2) Hoch reactivity — magnesium chips und dust sind flammable; machining requires Class D fire extinguishers. (3) Galvanic corrosion — magnesium müssen sein electrically isolated von steel fasteners mit washers oder coatings. (4) Higher raw material kosten als aluminum.
