前言锌合金自本世纪卅年代以来,主要被用作压铸合金,在重力铸造中极少应用。六十年代初期,国外开始研制锌铝重力铸造合金。在国际铅锌组织(ILZRO)发起的一项开发研究计划中,在美国新泽西州锌公司首先研制出成分为11％Al,0.75％Cu,0.02％Mg的ILZRO—12合金。当时已意识到这种合金具有出色的机械性能。以后在此基础上为改善该合金的机械性能进行了更深入的研究,经调整合金的成分后,最后以
Introduction Zinc alloy has been used mainly as a die-cast alloy since the beginning of this century and is rarely used in gravity casting. In the early sixties, foreign countries began to develop zinc-aluminum gravity casting alloy. In a development project initiated by the International Lead and Zinc Organization (ILZRO), zinc company New Jersey, USA, first developed ILZRO-12 alloy with 11% Al, 0.75% Cu and 0.02% Mg. It was realized that this alloy has excellent mechanical properties. After the basis of this in order to improve the mechanical properties of the alloy conducted a more in-depth study, after adjusting the composition of the alloy, the last
