系列: Aluminum Alloy
Magnesium-Silicon Alloy (Al-Mg-Si). AA designation 6111.
Overview
AA 6111 is an automotive body-sheet alloy in which raised copper content (about 0.5–0.9%) is added to the aluminium–magnesium–silicon base to strengthen paint-bake hardening and lift finished-panel strength above 6016. It combines excellent outer-panel surface quality with high dent resistance after the paint-cure cycle. The alloy is used for hood outer panels, trunk lids, and deck lids that demand the greatest dent resistance after baking.

说明
AA 6111 is an automotive body sheet aluminum alloy with elevated copper content (~0.5–0.9% Cu) added to the Al-Mg-Si base for enhanced paint-bake hardening and higher finished-panel strength compared to 6016. It offers excellent outer panel surface quality and high dent resistance after the automotive paint-cure cycle. The alloy is used in automotive hood outer panels, trunk lids, and deck lids requiring the highest dent resistance after baking.
