Embodiment 1

[0049] This embodiment discloses a method for preparing an aluminum alloy, comprising the following steps:

[0050] A. Melting

[0051] Melting Al, Si, Fe,, Mn, and Cu according to the mass fraction;

[0052] The melting temperature is 726°C;

[0053] Let stand for 10 minutes; then,

[0054] Stir, add Mg and Ti, mix well;

[0055] Refining degassing with nitrogen;

[0056] B. Deep well casting

[0057] Temperature 715°C;

[0058] Casting speed 90mm / min;

[0059] Adjust the frequency of the water pump to 28 Hz;

[0060] C. Hot rolling

[0061] Homogenization of cast aluminum ingots prior to hot rolling. The crystallization inside the aluminum ingot is uniformly adjusted by heating for a long time to ensure that the cast aluminum ingot is suitable for hot rolling.

[0062] The technological conditions of the homogenization treatment are: temperature 600° C., holding time 10 hours. The heat preservation temperature and heat preservation time of this homogeneous treatme...

Embodiment 2

Abstract

The invention discloses an aluminum alloy. The aluminum alloy comprises the following components of, 0.15%-0.25% of Si, 0.5%-0.6% of Fe, 0.95%-1.2% of Mn, 0.03%-0.05% of Ti, less than or equal to 0.08% of Mg and less than or equal to 0.05% of Cu. The invention further discloses a preparation method of the aluminum alloy; and the method comprises the steps of smelting, deep well casting, hot rolling, homogenizing, cold rolling and annealing to obtain an aluminum alloy plate. The aluminum alloy has good tensile strength and hardness, and meanwhile, has relatively high fracture elongation.

Description

technical field [0001] The invention relates to the field of aluminum alloys, in particular to an aluminum alloy with good flexibility and softness and a preparation method thereof. Background technique [0002] Various aluminum alloy products produced in the prior art are widely used, and also enrich various industrial production fields. However, due to the unreasonable formula and preparation method of the existing aluminum alloy products, certain characteristics are not outstanding, the cupping phenomenon is unstable, and the softness and flexibility cannot meet the requirements of high-end cookware sheets. Great constraints. Application number 2018109038638 Chinese invention patent application discloses the production method of aluminum alloy base material for IH rice cooker lid. The aluminum alloy prepared in this application has strong tensile strength, but its softness and flexibility are poor, and its elongation is It is 14%, which is not conducive to the forming o...
