Abstract

"EXTRUSãO DE LIGAS DE ALUMìNIO TENDO UMA ESTRUTURA SUBSTANCIALMENTE NãO-RECRISTALIZADA". A invenção refere-se a uma extrusão substancialmente não-recristalizada compreendendo cerca de 3,6 até cerca de 4,2% em peso de cobre, cerca de 1,0 até cerca de 1,6% em peso de magnésio, cerca de 0,3 até cerca de 0,8% em peso de manganês, cerca de 0,05 até cerca de 0,25% em peso de zircónio, o saldo sendo substancialmente alumínio, elementos incidentais e impurezas. A extrusão tem uma força de alongamento longitudinal de pelo menos cerca de 344,7 mPa (50 ksi) e uma resistência à tração longitudinal final de pelo menos cerca de 482,6 mPa (70 ksi). Em uma base preferida, as extrusões desta invenção incluem níveis muito baixos tanto de ferro quanto de silício, tipicamente da ordem de menos de 0,1% em peso cada um, e mais preferivelmente de cerca de 0,05% em peso ou menos de ferro e cerca de 0,03% em peso ou menos de silício.
