A kind of aluminum alloy material and its production process

Abstract

The invention provides an aluminum alloy material and a production process thereof. The aluminum alloy material comprises the following components of: aluminum, silicon, iron, magnesium, manganese, copper, zinc and lead, wherein the weight percentage of each component is as follows: 10.5% to 11.8% of silicon, 0 to 0.30% of iron, 0.10% to 0.25% of magnesium, 0.10% to 0.25% of manganese, 2.80% to 3.25% of copper, 0.10% to 0.25% of zinc, 0 to 0.20% of lead and the balances aluminum and inevitable impurities. The mass ratio of all components of ZLD113 aluminum alloy is further optimized and refined based on national standards so that the mechanical properties such as the tensile strength, the extension property and the hardness of the aluminum alloy can be limited and judged more accurately; the aluminum alloy can be conveniently applied to practical production and living; the potential safety hazards in use are reduced; the aluminum alloy produced by adopting the production process provided by the invention is low in impurity rate and high in purity; the mass percentage of each component is precise after a plurality of times of sampling inspection; few pinholes are generated; and thepercent of pass of products is high.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy production, in particular to an aluminum alloy material and a production process thereof. Background technique [0002] At present, there are more than a thousand types of aluminum and aluminum alloy materials, and more than 440 types are routinely used, which are covered in 1XXX to 9XXX alloys in terms of international conventions. Of course, many new alloys will be researched and developed according to their own needs, either in pre-research or development or application finalization. [0003] In the aluminum alloy smelting industry, as the price of non-ferrous metals continues to rise and the market is flooded with a lot of waste aluminum, recycled aluminum alloys are mostly used as casting production materials in the civil aluminum alloy industry, such as the auto parts industry, building materials industry, etc. The production process of the existing recycled casting aluminum alloy in...

Problems solved by technology

Due to the large range of each component, the various mechanical properties of the produced ZLD113 aluminum alloy are uneven, which will affect the mechanical properties of the aluminum alloy in severe cases, such as tensile strength, elongation and hardness, which cannot meet expectations. There are many hidden dangers
