Aluminum alloys for high-pressure die casting (HPDC) usually contain sufficient quantities of dissolved iron to reduce die wear and soldering. Unfortunately, iron reduces ductility, making the product unsuitable for crash-resistant automotive components. Recent improvements in machine design and new alloys allow the production of high ductility, structural HPDC components. This paper details the chemical and metallurgical factors underlying this development .

结构高压压铸铝合金的冶金学

用于高压压铸的铝合金(HPDC)通常包含足够量的溶解铁,以减少模具磨损和焊接。不幸的是,铁降低了延展性,使该产品不适合用于耐碰撞的汽车部件。机器设计和新合金的最新改进允许生产高延展性的结构HPDC组件。本文详细介绍了这一发展背后的化学和冶金因素。
