Abstract

La presente tiene por objeto una chapa para pieza embutida de revestimiento o estructura de carrocería de automóvil, también llamada carrocería en bruto, de aleación de aluminio, de composición (% en peso): Si: 0,85 - 1,20; Fe: < 0,30; Cu: 0,10 - 0,30 Mg: 0,70 - 0,90; Mn: < 0,30; Zn: 0,9 - 1,60; V: 0,02 - 0,30; Ti: 0,05 - 0,20; otros elementos < 0,05 cada uno y < 0,15 en total, resto aluminio, que presenta, tras solubilización, temple, revenido previo o reversión, eventual maduración a temperatura ambiente comprendida entre 72 h y 6 meses, deformación previa por tracción controlada de un 2% y tratamiento de cocción de las pinturas de 20 min. a 185ºC, un límite elástico Rp₀,₂ de por lo menos 300 MPa. Las chapas según la presente permiten reducir el espesor de las piezas, cumpliendo a la vez con todas las otras propiedades requeridas. Reivindicación 10: Proceso de fabricación de una chapa según una de las reivindicaciones 1 a 9, que consta de las siguientes etapas: colada típicamente semicontinua vertical de una placa y su eventual escalpado, homogeneización de dicha placa a una temperatura de 550 a 570ºC con mantenimiento de entre 2 y 12 h, preferentemente de entre 4 y 6 h, seguida de un enfriamiento rápido, calentamiento a una temperatura comprendida entre 450 y 550ºC con mantenimiento de 30 min. a 3 h, preferente y sensiblemente de 2 h, laminado en caliente de la placa en una banda cuyo espesor está comprendido entre 3 y 10 mm, laminado en frío hasta el espesor final, solubilización de la banda laminada a una temperatura superior a la temperatura de solvus de la aleación, pero evitando la quemadura, es decir entre 550 y 570ºC durante 5 s a 5 min., seguida del temple a una velocidad de más de 50ºC/s y preferentemente más de 100ºC/s, revenido previo, o reversión, por bobinado a una temperatura de por lo menos 60ºC seguido de un enfriamiento al aire libre de la bobina obtenida.
