Abstract

The invention discloses a rare earth aluminum-manganese alloy foil used for an aluminum honeycomb panel core and a preparation method thereof. The alloy foil uses Al-Mn alloy as basis, and comprises chemical compositions by mass percent: less than or equal to 0.3 % of Si, less than or equal to 0.6 % of Fe, 0.12-0.18 % of Cu, 1.1-1.4 % of Mn, 0.10-0 .25 % of La, less than or equal to 0.01 % of Mg, less than or equal to 0.03 % of Zn, less than or equal to 0.05 % of Ti, and the balance being Al. The preparation method uses a continuous roll-casting method, and comprises firstly producing casting rolls, secondly rolling the casting rolls, and annealing by using a furnace gas temperature control way. The invention provides a rare earth aluminum-manganese alloy foil which is uniform in crystal grain and high in intensity, and does not has intergranular corrosion and segregation; the preparation method combines casting and rolling, and thus improves compactness of metal organization, eliminates defects of shrinkage cavity and loosening, reduces segregation, eliminates head and tail cutting, increases a yield by more than 15 %, realizes continuous and automatic casting-rolling production, and shortens production period.

Description

technical field [0001] The invention relates to the field of processing aluminum alloy materials and aluminum alloy plates, in particular to a rare earth aluminum manganese alloy foil used for the core of an aluminum honeycomb panel and a preparation method thereof. Background technique [0002] Honeycomb aluminum sheet has excellent properties such as high wind pressure resistance, shock absorption, sound insulation, heat preservation, flame retardancy and high strength, and is currently the preferred lightweight material for various industries and construction industries. At present, the output of aluminum honeycomb panels in my country is increasing in geometric progression. Al-Mn alloy foil is the key material for manufacturing honeycomb aluminum panel cores, and the production method of Al-Mn alloy foil has always been the rolling process mainly using hot-rolled blanks and cold-rolled Foil rolling processing. Since aluminum-manganese alloys are non-heat-treatable streng...
