作为一种新型的工程材料——高铝锌基合金(ZA合金),近年来,以其良好的机械性能和铸造性能,越来越受到材料工作者和铸造工作者的重视,并逐步在工业应用中发挥其优势。由于该合金在机械性能方面可与普通铸铁、可锻铸铁和某些铝合金比美,而在耐磨性方面又可以与锡青铜等耐磨合金类比,此外,该合金还具有容易加工、容易熔炼、节能、无 As a new type of engineering material, high aluminum-zinc-based alloy (ZA alloy), in recent years, with its good mechanical properties and casting performance, more and more attention by material workers and foundry workers, and gradually in the industrial Application to play its advantages. As the alloy in mechanical properties with ordinary cast iron, malleable iron and some aluminum than the United States, but also in wear resistance and tin bronze and other wear-resistant alloy analogy, in addition, the alloy also has easy processing, easy melting, energy saving ,no
