镁的强度与重量比好,可铸性也好,这是大家公认的。但是,人们对镁也有一些误解,这些误解使设计工程师们不把它作为一种压铸材料来使用。新型的高纯度镁压铸合金,以及在无熔剂的热腔压铸工艺方面的进步,大大地改变了原来评价镁压铸件的成本和性能的传统准则。镁压铸件现在已胜过工程塑料,可以制做许多产品零件,真可谓“士别三日,刮目相 Magnesium strength and weight ratio is good, castability Ye Hao, it is generally accepted. However, there are some misunderstandings about magnesium, which mislead design engineers from using it as a die-cast material. New high purity magnesium die-cast alloys, as well as advances in fluxless hot cavity die casting, have dramatically changed the traditional guidelines for evaluating the cost and performance of magnesium die-castings. Magnesium die-casting is now better than engineering plastics, can make many product parts, it can be described as "Do not three days, scalloped
