早在第二次世界大战期间,铜、锡资源短缺,德国就研制了锌基合金代替青铜作轴套材料,由于该合金比重大,延伸率及尺寸稳定性能都不理想,加上自然时效老化问题长期得不到解决,战后相当一段时间内,锌基合金的应用受到限制,未引起人们的重视,直到60年代初,才有“国际铅锌研究组织”研制出ILZRO12,以适应当时能源紧张的局面。70年代,加拿大NORANDA矿业公司和美国EASTERN合金公司相继研制成功ZA27和ZA8,逐步
As early as during the Second World War, the shortage of copper and tin resources, Germany developed a zinc-based alloy instead of bronze as a sleeve material, due to the large proportion of alloy, elongation and dimensional stability are not ideal, coupled with natural aging The problem has not been solved for a long time. For a long time after the war, the application of zinc-based alloys was limited and people’s attention was not paid attention. Until the early 1960s, ILZRO12 was developed by International Lead and Zinc Research Organization to adapt to the current energy Tense situation. 70 years, Canada NORANDA Mining Company and the United States EASTERN alloy companies have successfully developed ZA27 and ZA8, and gradually
