自2014年12月份以来，美铝(Alcoa Inc.) 陆续发布了 Micromill 技术的一些细节。2015年9月份宣布与Ford在下一代汽车用铝合金板材上的合作。

       Micromill 技术是一种高效生产铝合金板材的技术，从公布的一些信息来看，美铝的Micromill 技术是采用水平式高速铸轧高效生产铝合金薄板，推测是在铝合金水平式高速铸轧生产薄板的技术上实现了较大的突破，解决了比较大的技术问题。

       Micromill 技术的特点如下：

• Micromill produces automotive alloy that is 40% more formable and 30% stronger than incumbent aluminum, while meeting stringent automotive surface quality requirements

• Automotive parts made with Alcoa Micromill^® material will be twice as formable and 30%  lighter than parts made from high strength steel

• Alcoa Micromill reduces time to transform molten metal into aluminum coil from 20 days to 20 minutes

• Micromill technology has the flexibility to transition seamlessly between producing rolled products for automotive, industrial and packaging markets

• Alcoa has completed successful customer product trials and is qualifying Micromill material for next-generation automotive platforms

   总结起来就是：与现有铝合金板材相比，成形性提高40%，强度提高30%；从铝液到到卷板的时间从20天缩短到20 min，更优良的表面质量。
