铝板通常是指纯铝板，是由铝锭压制而成，形状为长方形，厚度在0.2mm-500mm之间，可以按照合金成分和厚度来分类。
Aluminum plate usually refers to pure aluminum plate, which is pressed from aluminum ingots, with a rectangular shape and a thickness between 0.2mm-500mm. It can be classified according to alloy composition and thickness.
①按照合金成分可分为纯铝板（纯铝制成）、合金铝板（以铝为主要成分，加入其它的合金元素制成铝合金板材）、复合铝板（多种材料复合而成，作特殊用途使用）；
① According to the alloy composition, it can be divided into pure aluminum plate (made of pure aluminum), alloy aluminum plate (made of aluminum as the main component and added with other alloy elements to make aluminum alloy plate), and composite aluminum plate (made of multiple materials for special purposes);
②按照厚度可分为三种：薄板（厚度为0.15mm-2.0mm）、常规板（厚度为2.0mm-6.0mm）、中板（6.0mm-25.0mm）、厚板（25.0mm-200mm）、超厚板（200mm以上）。
② According to thickness, it can be divided into three types: thin plate (thickness 0.15mm-2.0mm), regular plate (thickness 2.0mm-6.0mm), medium plate (6.0mm-25.0mm), thick plate (25.0mm-200mm), and ultra thick plate (over 200mm).
用途：不同厚度的铝板用于不同的领域，薄板可用来作照明用具用、家用电器如冰箱或微波炉使用、电梯、汽车装饰件；厚板可用于航空航天飞机、军工用品、轮船的甲板等。
Usage: Aluminum plates of different thicknesses are used in different fields, and thin plates can be used for lighting appliances, household appliances such as refrigerators or microwaves, elevators, and car decorations; Thick plates can be used for decks of aerospace shuttles, military supplies, ships, etc.

铝合金板是在铝中加入各种不同的合金元素，如镁、铜、铬、硅、锌等通过挤压、时效等而制成的一种铝合金型材材料，用于各种不同的工业领域。铝合金板的厚度在2mm以上，也是铝板的一种，它可以分为很多不同的系列，不同的系列合金成分不同，用途也存在差异。
Aluminum alloy plate is an aluminum alloy profile material made by adding various alloy elements such as magnesium, copper, chromium, silicon, zinc, etc. to aluminum through extrusion, aging, etc., used in various industrial fields. The thickness of aluminum alloy plate is over 2mm, which is also a type of aluminum plate. It can be divided into many different series, with different alloy compositions and uses.
铝合金板可分为7大系列，分别为1系纯铝板；2系铝铜合金板；3系铝锰合金板；4系铝硅合金板；5系铝镁合金板；6系铝镁硅合金板；7系铝镁锌铜合金。
Aluminum alloy plates can be divided into 7 series, including 1 series of pure aluminum plates; 2 series aluminum copper alloy plate; 3 series aluminum manganese alloy plate; 4 series aluminum silicon alloy plate; 5 series aluminum magnesium alloy plate; 6 series aluminum magnesium silicon alloy plate; 7 series aluminum magnesium zinc copper alloy.
用途：每一系列的铝合金板的用途都不同，例如6系铝合金板是以6063-T5为代表的合金板材，应用范围广，灵活性好。可以用来制作各种流水线框架，工作台，设备机罩，机箱机柜等等。
Usage: Each series of aluminum alloy plates has different uses, for example, the 6-series aluminum alloy plates are alloy plates represented by 6063-T5, with a wide range of applications and good flexibility. It can be used to make various assembly line frames, workbenches, equipment covers, chassis cabinets, and so on.
