Abstract

The invention discloses an aluminum alloy thick plate for a high-strength mold and a production method thereof. The aluminum alloy thick plate has the following chemical elements in percentage by mass: Si not more than 0.25%, Fe not more than 0.45%, 1.5-1.8% of Cu, Mn not more than 0.25%, 2.4-2.8% of Mg, 0.19-0.25% of Cr, 5.3-5.8% of Zn, 0.02-0.03% of Ti, and the balance of Al. Firstly, raw materials are put in a smelting furnace for smelting, and are put in a refining furnace for refining; obtained molten aluminum is stood, refined and cast; and an obtained ingot performs surface milling, thermalization, hot rough rolling, quenching, stretching and aging in sequence to obtain the aluminum alloy thick plate for the high-strength mold. The aluminum alloy thick plate for the mold with high strength and flatness, no hole and slag in the internal and higher ductility and yield strength is prepared.

Description

[0001] 1. Technical field: [0002] The invention belongs to the technical field of aluminum alloys, and in particular relates to an aluminum alloy thick plate for a high-strength mold and a production method thereof. [0003] 2. Background technology: [0004] At present, molds are mainly made of steel. The advantages of steel are high strength, good wear resistance and not easy to deform after quenching. However, there are still defects such as easy to rust, heavy installation, and poor elasticity. Ordinary aluminum alloys such as 1-series, 3-series, 4-series, 5-series, and 8-series cannot be used as molds, mainly because such alloys have low strength, low hardness, and cannot be strengthened by heat treatment. If they are made into mold materials, they will cause serious deformation and scrap;7 Series aluminum alloys are the most commonly used aluminum alloys at present. The strength and hardness of 7 series aluminum alloys are poor in hot-rolled and cold-rolled states, but ...
