Die Casting - Magnesium die cast
Today I got was in class where Meridian Technologies, Premier Mag die casting company in North america was having their BDM( bizz development Manager) as the chief speaker.
Here is what he got to say..
Mag has two major grade called AZ ( high strength ) and AM ( high ductility) alloy. China has lots of magnesite ore and price lock up for long term customers option was available. Magnesium rates are expected to stay pretty much the same ( around $1.10/lb) while Al is expected to grow above the present market rates.
Al absorbs Hydrogen , which causes porosity in the molten state, so the newer techniques involve degassing molten Al before pouring them into the cavity.
Mag market grows by 10% every year for the next 5 years. Mag products are good EMI shielder.
There were case studies in Body & door panels made of Magnisium like Engine Cradle ( GM Corvette), Rear Lift gate
