Abstract

"PROCESSO PARA PREPARAçãO DE UMA CHAPA DE LIGA DE ALUMìNIO COM FLEXIBILIDADE MELHORADA E A CHAPA DE LIGA DE ALUMìNIO DELE PRODUZIDA". A presente invenção refere-se a um processo para produção de uma chapa de liga de alumínio tendo uma excelente flexibilidade para uso em conformação de painéis para automóveis. é usada uma liga de alumínio compreendendo 0,5 - 0,75% em peso de Mg, 0,7 - 0,85% em peso de Si, 0,15 - 0,35% em peso de Mn, 0,1 - 0,3% em peso de Fe, opcionalmente 0,2 0,4% em peso de Cu e o saldo sendo Al e as impurezas incidentais, e essa liga é fundida em lingotes por fundição semi-contínuo. O lingote é submetido à laminação a quente e à laminação a frio, seguido por tratamento térmico em solução da chapa conformada. Esse material chapa é então pré-envelhecido resfriando-se rapidamente a partir de uma temperatura inicial de pré-envelhecimento de pelo menos 80<198>C até a temperatura ambiente a uma taxa de resfriamento de mais de 5<198>C/hora.
