合金铝板和纯铝板区别：

The difference between alloy aluminum plate and pure aluminum plate:

1、用途不同

1. Different uses

由于铝合金成分不同，铝板与铝合金板的特性也不尽相同，适用范围也大不相同。铝板主要用于电器产品、模具加工、船板等，而铝合金板主要用于工业生产铝型材，广泛应用于城市轨道、电子电气等方面。

Due to the different compositions of aluminum alloys, the characteristics and applicability of aluminum plates and aluminum alloy plates are also greatly different. Aluminum plates are mainly used for electrical products, mold processing, ship plates, etc., while aluminum alloy plates are mainly used for industrial production of aluminum profiles, which are widely used in urban rail transit, electronics and electrical, etc.

2、强度不同

2. Different intensities

合金铝板的强度应大于铝板的强度。铝合金板材是在铝板的基础上加入铜、硅、镁、锌、锰等铝合金元素，其强度将超过铝板的强度。合金铝板的耐蚀性比铝板好得多。因此，在一些有腐蚀的制造业中，铝合金板比铝板更受欢迎。

The strength of the alloy aluminum plate should be greater than that of the aluminum plate. Aluminum alloy sheet is made by adding aluminum alloy elements such as copper, silicon, magnesium, zinc, manganese, etc. on the basis of aluminum sheet, and its strength will exceed that of aluminum sheet. The corrosion resistance of alloy aluminum plate is much better than that of aluminum plate. Therefore, in some corrosive manufacturing industries, aluminum alloy plates are more popular than aluminum plates.

3、合金成分不同

3. Different alloy compositions

铝板是由铝制成的板材，根据合金成分可分为纯铝板、合金铝板、复合铝板和包铝铝板，还可按照尺寸分为常规板、中厚板、厚板和薄板，铝板就是指的纯铝板。铝合金板是以铝为主要原材料，加入铜、镁、锌等金属而成的铝型材。

Aluminum plate is a sheet made of aluminum, which can be divided into pure aluminum plate, alloy aluminum plate, composite aluminum plate, and aluminum clad aluminum plate according to the alloy composition. It can also be divided into conventional plate, medium thick plate, thick plate, and thin plate according to size. Aluminum plate refers to pure aluminum plate. Aluminum alloy plate is an aluminum profile made mainly from aluminum as the main raw material, with the addition of metals such as copper, magnesium, zinc, etc.

4、应用领域不同

4. Different application fields

铝板主要用于家用电器、模具制造、船板等，铝合金板主要用于工业型材，在航空航天、轨道交通、电子电器方面应用广泛。

Aluminum plates are mainly used for household appliances, mold manufacturing, ship panels, etc. Aluminum alloy plates are mainly used for industrial profiles and are widely used in aerospace, rail transit, and electronic appliances.

5、概念不同

5. Conceptual differences

铝合金是工业中应用广泛的一类有色金属结构材料。铝板是指用铝锭轧制加工而成的矩形板材。

Aluminum alloy is a widely used non-ferrous metal structural material in industry. Aluminum plate refers to a rectangular plate made by rolling and processing aluminum ingots.
