Abstract

The invention relates to an aluminum alloy checkered plate in the state of 4017-H2X and a preparation method thereof. The checkered plate comprises the following raw materials in percentage by weight:0.6-1.6% of Si, less than or equal to 0.7% of Fe, 0.1-0.5% of Cu, 0.6-1.2% of Mn, 0.1-0.5% of Mg, less than or equal to 0.2% of Zn, less than 0.05% of other single impurities, less than 0.15% of total impurities and the balance of Al. The preparation method comprises the following steps of material preparing, smelting and casting; ingot soaking, machining and milling surface; hot rolling; cold rolling and cogging; cold rolling embossing; continuous annealing; and tension correction or crosscutting. The checkered plate in the state of 4017-H22 or 4017-H24 prepared by the preparation method hasno naked eye crack, no orange peel lines and fine surface after being bent at 90 degrees. The checkered plate prepared by the preparation method can be painted and is suitable for being used as building materials and manufacturing decorative parts.

Description

technical field [0001] The invention relates to the field of metal manufacturing, in particular to a 4017-H2X state aluminum alloy checkered plate and a manufacturing method thereof. Background technique [0002] Ordinary checkered plates are mostly processed with 1060, 3003, and 5052 aluminum alloys in series 1, 3, and 5 as the base, and rarely use 4-series aluminum alloys as the base. In comparison, the 1-series and 3-series aluminum alloy checkered plates have lower hardness and slightly poorer wear resistance, and are mostly used for rust prevention in ordinary environments and application requirements that are not strict. Although the corrosion resistance of the 5-series aluminum alloy plate is better, the anodic oxidation effect is slightly worse than that of the 6-series aluminum alloy. The 4-series tread plate has particularly good wear resistance and good anti-slip ability. It is usually used as building materials and manufacturing decorative parts, such as transpo...
