Beschreibung
Zusammenfassung:	The invention provides high-strength high-conductivity Al-Fe-La-xCu aluminum alloy foil. The foil is prepared from 0.06-0.3wt% of Fe, 0.06-0.2wt% of La, 0-0.3 wt% of Cu, and the balance Al. The aluminum alloy foil maintains both high strength and high conductivity, the tensile strength of the cold-rolled aluminum alloy foil is 203-235 MPa, and the conductivity is 56-59% IACS; and after being subjected to heat treatment at 160 DEG C for 5 hours, the aluminum alloy foil has a tensile strength of 180-219 MPa and a conductivity of 56-58.7% IACS. 本发明提供一种高强高电导率Al-Fe-La-xCu铝合金箔，成分组成包括Fe：0.06～0.3wt％、La：0.06～0.2wt％、Cu：0～0.3wt％，其余包括铝。本发明的铝合金箔同时保持了高强度和高电导率，冷轧态的铝合金箔抗拉强度为203～235MPa，电导率为56～59％IACS；经160℃5小时热处理后的铝合金箔抗拉强度为180～219MPa，电导率为56～58.7％IACS。
