The theoretical weight calculation formula for aluminum plates is as follows:

重量（单位：千克）= 长度（单位：毫米）× 宽度（单位：毫米）× 厚度（单位：毫米）× 密度（单位：千克/立方米）

Weight in kilograms=length in millimeters ×  Width in millimeters ×  Thickness in millimeters ×  Density in kilograms per cubic meter

其中，密度是铝的密度，一般为2.7克/立方厘米或2700千克/立方米。

Among them, density is the density of aluminum, typically 2.7 grams per cubic centimeter or 2700 kilograms per cubic meter.

需要注意的是，这只是铝板的理论重量，实际重量可能会因为制造过程和材质差异而有所偏差。另外，如果铝板存在其他形状或结构，例如弯曲、孔洞等，也需要进行额外的计算来得到准确的重量。

It should be noted that this is only the theoretical weight of the aluminum plate, and the actual weight may vary due to differences in manufacturing process and materials. In addition, if the aluminum plate has other shapes or structures, such as bending, holes, etc., additional calculations are also required to obtain accurate weight.

怎样计算铝板重量？

How to calculate the weight of aluminum plates?

重量计算公式：m=ρ*V（m是质量，ρ是密度，V是体积）不一样合金的铝板密度（ρ）是不一样的，在这里以3mm*1000*2023的1060铝板（也称纯铝板）作为例子。这张铝板的重量（m）=2.71（密度）*3（厚度/毫米）*1（宽度/米）*2（长度/米）=16.26kg。

Weight calculation formula: m= ρ* V (m is the mass, ρ Density, V is volume) The density of aluminum plates with different alloys（ ρ） It's different. Here, we take a 3mm * 1000 * 2023 1060 aluminum plate (also known as pure aluminum plate) as an example. The weight of this aluminum plate (m)=2.71 (density) * 3 (thickness/mm) * 1 (width/meter) * 2 (length/meter)=16.26kg.

纯铝的密度（ρ=2.7g/cm3）比较小，大概是铁的1/3。但是，纯铝的强度很低，退火状态σb值约为8kgf/mm2，故不要作结构材料。

Density of pure aluminum（ ρ= 2.7g/cm3) is relatively small, about one-third of iron. However, the strength of pure aluminum is very low and in an annealed state σ The value of b is approximately 8kgf/mm2, so it should not be used as a structural material.

通过长时间的生产实践和科学实验，大家渐渐以加入合金元素及运用热处理等方式来强化铝，这个问题就得到了一系列的铝合金。

Through long-term production practice and scientific experiments, people have gradually strengthened aluminum by adding alloying elements and using heat treatment methods, resulting in a series of aluminum alloys.

添加一定元素形成的合金在保持纯铝质轻等优点的同时还能具有非常高的强度，σb值分别可达24～60kgf/mm2。

The alloy formed by adding certain elements can maintain the advantages of pure aluminum being lightweight while also possessing very high strength, σ The b values can reach 24-60kgf/mm2, respectively.

这样让其“比强度”（强度与比重的比值σb/ρ）胜过不少合金钢，成为理想的结构材料，广泛用于机械制造、运输机械、动力机械及航空工业等方面，飞机的机身、蒙皮、压气机等常以铝合金制造，以减轻自重。

This makes it "specific strength" (the ratio of strength to specific gravity) σ B/ ρ） Compared to many alloy steels, it has become an ideal structural material and is widely used in mechanical manufacturing, transportation machinery, power machinery, and aviation industry. The fuselage, skin, and compressor of aircraft are often made of aluminum alloy to reduce self weight.
