加工性能强AZ91D镁合金 散热快

 镁合金　　镁合金都具有密度小的特点，特别是某些镁-锂合金（见前），密度甚至低于1。美英俄等国正在研制含钇镁合金。一种Mg-8.5Y-1.25Zn-0.5Zr合金，其密度小于1.9g·cm-3 ，抗拉强密度420Mpa， 0.2%屈服强度360Mpa，比现有任何一种变形镁合金的都高，同高强度铝合金强度相当。Magnesium alloy

Magnesium alloy has the characteristics of low density, especially some lithium magnesium alloy (see-before), density and less than one. American and British Russia and other countries are developing magnesium alloys containing y. A kind of Mg-8.5 Y 1.25 Zn 0.5 Zr alloy, its density is less than 1.9 g · cm-3, tensile strong density of 420 Mpa, 0.2% yield strength 360 Mpa, than the existing any kind of deformation of magnesium alloys are high, with high strength is the strength of aluminum.

根据有关研究,汽车所用燃料的60%是消耗于汽车自重,汽车自重每减轻10%,其燃油效率可提高5%以上;汽车自重每降低100 kg,每百公里油耗可减少0.7 L左右,每节约1 L燃料可减少CO2排放2.5 g，年排放量减少30%以上。所以减轻汽车重量对环境和能源的影响非常大，汽车的轻量化成必然趋势。
