变形铝板的分类方法很多。目前，世界上大多数国家通常按照以下三种方法对其进行分类:
　　There are many classifications of deformed aluminium sheets. At present, most countries in the world usually classify them according to the following three methods:
　　(1)根据合金的状态图和热处理特点，将其分为两大类:非热处理强化铝板和热处理强化铝板。非热处理强化铝板:纯铝，
　　(1) According to the state diagram and heat treatment characteristics of the alloy, it can be divided into two categories: non-heat treatment strengthened aluminium plate and heat treatment strengthened aluminium plate. Non-heat treatment strengthened aluminium sheet: pure aluminium,
　　铝锰、铝镁、铝硅合金等。热处理强化铝板包括铝镁硅、铝铜、铝锌镁合金等。
　　Al-Mn, Al-Mg, Al-Si alloys, etc. Heat treatment strengthened aluminium sheet includes aluminium magnesium silicon, aluminium copper, aluminium zinc magnesium alloy and so on.

　　(2)根据合金的性能及使用,它可以分为:工业纯铝、切割铝板、耐热铝合金板、低威力铝板,中度铝板,高强度铝合金板(duraluminum),于铝板(duraluminum)防锈铝板,伪造的铝板和特殊铝板等。
　　(2) According to the properties and usage of the alloy, it can be divided into industrial pure aluminium, cutting aluminium plate, heat-resistant aluminium alloy plate, low-power aluminium plate, moderate aluminium plate, high-strength aluminium alloy plate (duraluminum), rust-proof aluminium plate in aluminium plate (duraluminum), forged aluminium plate and special aluminium plate.

　　(3)根据合金中所含的主要元素，可分为:工业纯铝(1xxx系统)、铝铜合金(2xxx系统)、铝锰合金(3xxx系统)、铝硅合金(4xxx系统)、铝镁合金(5xxx系统)、铝镁硅合金(6xxx系统)、铝锌镁铜合金(7xxx系统)、LXXX系统。7xxx系列(8xxx系列)和储备合金组(9xxx系列)以外的合金。吗?
　　(3) According to the main elements contained in the alloy, it can be divided into: industrial pure aluminium (1xxx system), aluminium-copper alloy (2xxx system), aluminium-manganese alloy (3xxx system), aluminium-silicon alloy (4xxx system), aluminium-magnesium alloy (5xxx system), aluminium-magnesium-silicon alloy (6xxxx system), aluminium-zinc-magnesium-copper alloy (7xxx system) and LXXX system. Alloys other than 7xxx series (8xxx series) and reserve alloy group (9xxx series). Do you?
　　这三种分类方法各有特点，有时相互交叉，有时相互补充。在工业生产中，大多数国家采用第三种方法进行分类，即按合金中所含主要元素的四位数法进行分类。该分类方法能从本质上反映合金的基本性能，便于编码、存储和计算机管理。我国目前也采用四位数字进行分类。
　　These three classification methods have their own characteristics, sometimes overlapping and sometimes complementing each other. In industrial production, most countries use the third method to classify, i. e. according to the four-digit method of major elements in alloys. This classification method can essentially reflect the basic properties of alloys and is easy to code, store and manage by computer. At present, four digits are also used for classification.
