Cov no hais txog magnesium alloys
Jun 22, 2022
Hais txog cov khoom hais txog magnesium alloys, magnesium yog ib qho ntawm cov hlau lub teeb. Lub ntiajteb txawj nqus ntawm magnesium yog 1.74g / cm3. Magnesium alloys yog 36% sib zog dua aluminium alloys, 73% sib zog dua zinc alloys, thiab 77% sib zog dua hlau.
Magnesium muaj lub zog tshwj xeeb, muaj zog tshwj xeeb, zoo thermal conductivity thiab hluav taws xob conductivity, thiab muaj zoo electromagnetic shielding, damping, vibration damping, machinability thiab tsawg ua nqi, ua zog tsuas yog 70% ntawm txhuas alloy thiab yooj yim rau recycle, thiab lwm yam. qhov zoo.
Lub zog tshwj xeeb ntawm magnesium alloy yog siab dua li ntawm aluminium alloy thiab steel, me ntsis qis dua li ntawm fiber ntau cov yas nrog lub zog tshwj xeeb tshaj plaws; qhov tshwj xeeb nruj yog piv rau cov aluminium alloy thiab steel, ntau dua li ntawm fiber ntau cov yas; Qhov hnav tsis kam yog qhov zoo dua li cov hlau tsis muaj cov pa roj carbon tsawg, Nws tau tshaj qhov tuag-casting aluminium alloy A380; Qhov kev vibration damping kev ua tau zoo thiab kev sib nqus tiv thaiv kev ua tau zoo yog qhov zoo tshaj rau cov aluminium alloys.
Magnesium alloys yog cov hlau uas muaj magnesium-based thiab lwm yam khoom. Lub ntsiab alloying ntsiab yog txhuas, zinc, manganese, cerium, thorium thiab ib tug me me ntawm zirconium los yog cadmium. Tam sim no, magnesium-aluminium alloys tau dav siv, ua raws li magnesium-manganese alloys thiab magnesium-zinc-zirconium alloys.
Ntxiv rau nws qhov tsis tshua muaj lub ntiajteb txawj nqus, magnesium muaj ntau lwm yam khoom siv lub cev zoo uas ua rau qee zaum muaj txiaj ntsig ntau dua li txhuas thiab yas hauv kev siv cov khoom siv hauv tsheb. Lub ntsiab zoo ntawm magnesium lub cev muaj zog yog: 30 lub sij hawm siab dua kev co damping kev ua tau zoo tshaj txhuas; 200 npaug ntawm thermal conductivity dua li yas; nws cov thermal expansion kev ua tau zoo tsuas yog 1/2 ntawm cov yas.
