Abstract

The invention relates to a novel aluminum alloy material, in particular to an aluminum-manganese-magnesium base alloy containing copper, nickel and cerium. The compositions in weight percentage of the aluminum-manganese-magnesium-copper-nickel-cerium alloy are 0.4 to 0.7 percent of copper, 0.2 to 0.7 percent of nickel, 0.02 to 0.05 percent of cerium, 0.8 to 1.3 percent of manganese, 0.6 to 1.2 percent of magnesium, and the balance being aluminum and inevitable impurity elements. The aluminum-manganese-magnesium-copper-nickel-cerium alloy has the advantages that the alloy can simultaneously have high strength and good thermal stability, thermal fatigue property and fluidity, and is suitable for manufacturing thin-wall pipe fittings after adoption of multicomponents of the copper, the nickel and the cerium for composite microalloying on the basis of the aluminum-manganese-magnesium base alloy. The invention also provides a method for manufacturing the aluminum-manganese-magnesium-copper-nickel-cerium alloy.

Description

technical field

[0001] The invention relates to a novel aluminum alloy material, in particular to an Al-Mn-Mg base alloy containing Cu, Ni and Ce and a manufacturing method thereof. Background technique

[0002] The fixing rollers used in laser printers and copiers require light weight, non-magnetic properties, excellent thermal conductivity, heat resistance and corrosion resistance, etc. Therefore, the fixing rollers are usually made of antirust aluminum alloys that cannot be strengthened by heat treatment. The working temperature of the fixing roller generally does not exceed 200°C, and it works alternately between hot and cold. Therefore, the aluminum alloy used to make the fixing roller is required not only to have sufficient strength in the annealed state, but also to have excellent thermal stability and thermal fatigue performance. At home and abroad, Al-Mg anti-rust aluminum alloy 5052 or 5056 alloy has been mostly used to manufacture fixing rollers. However, since th...
