Nine Characteristics of Magnesium Alloy Die Casting Die Temperature Machine
1.Theproportionoflightmagnesiumalloyisonly18G/CM3,thatofaluminumalloyis27G/CM3,thatofmagnesiumalloyis30%lighterthanthatofaluminumalloyand80%lighterthanthatofsteel.Therefore,magnesiumalloysinautomotiveandportableelectronicproductshavebecomeidealmaterialsforpartsmanufacturing.2.Strengthmagnesiumalloyshaveexcellentstrength/weightratioinengineeringmaterialssuchasmetalsandplastics.3.Theallowablewallthicknessofmagnesiumalloycanreach0.6mmundertheconditionofgoodstructure,whichcannotbeachievedbyplasticsunderthesamestrength.Thedie-castingperformanceofaluminiumalloyshouldbeabove1.2-1.5mmtocomparewiththatofmagnesiumalloy.Magnesiumalloysareeasytodie-castandsuitableformassdie-castingproduction(theproductionspeedcanreach1.5timesthatofaluminium).Inaddition,thewearofmagnesiumalloydieisalsolowerthanthatofaluminum.4.Magnesiumalloyshaveexcellenthystereticandshockabsorptionproperties.Theycanabsorbshockandnoise.Theycanbeusedasequipmenthousingtoreducenoisetransmission,preventimpactandpreventdentdamage.5.Therigidityofrigidmagnesiumalloyistwicethatofaluminiumandhigherthanthatofmostplastics.Magnesiumhasgoodstressresistance.6.MagnesiumalloyswithhighEMIperformancehavegoodelectromagneticwavebarrierfunctionandaresuitablefortheproductionofelectronicproducts.7.Magnesiumhasbettermachinabilitythanaluminiumandzinc,whichmakesiteasiertocut.8.Thespecificheatcapacityofmagnesiumalloyindiecastingdietemperaturemachineissmall,andthecoolingspeedofalloyliquidisfast.9.Magnesiumalloydie-castingtemperaturemachinehaslowaffinitywithdiesteelandisnoteasytoadheretothedie.
