制造铝饮料罐罐盖所需要的材料性能,随着这一工业在过去30多年内的发展产生了极大的变化。本文追溯了罐盖坯料用合金从50年代至现在的发展过程,回顾了早期使用 H19状态的刚性容器板材并导致5182合金开发的经历,着重说明了其加工硬化及不完全退火性能,并讨论了这一工业中迫使改善产品冶金性能的一些变化,尤其是卷材涂层及新的罐盖结构设计。 The material properties needed to make aluminum beverage can lids have changed dramatically as the industry has evolved over the past 30 years. This paper traces the development of the alloy for cans and billets from the 1950s to the present and reviews the experience of early use of rigid container plates in H19 state and leads to the development of 5182 alloy with emphasis on work hardening and incomplete annealing. Some changes in the industry that have forced the improvement of metallurgical properties of products, especially coil coatings and new can-lid designs.
