铝卷的密度是多少

来源:

铝卷带属于纯铝卷系列其强度相对比较低,铝卷具有优良的延展性、成形性、焊接性和耐腐性;阳极氧化后可进一步提高耐腐性,铝卷同时获得美观的表面;但不可热处理强化。 纯铝卷系列根据较后两位阿拉伯数字来确定这个系列的较低含铝量,比如1100系列较后两位阿拉伯数字为00,铝卷 根据牌号命名原则,铝卷含铝量必须达到99.00%以上方为合格产品。我国的铝合金技术标准(GB/T3880-2006)中也明确规定1100含铝量达到99.0%。
Aluminum coil strip belongs to pure aluminium coil series, its strength is relatively low, and aluminium coil has excellent ductility, formability, weldability and corrosion resistance; corrosion resistance can be further improved after anodizing, while aluminium coil can obtain beautiful surface; but it can not be strengthened by heat treatment. Pure aluminium coil series determines the minimum aluminium content of this series according to the last two Arabic numbers, such as the last two Arabic numbers of 1100 series are 00, and aluminium coil according to the international brand naming principle, aluminium coil must reach 99.00% or more before it is qualified product. China's technical standard for aluminium alloy (GB/T3880-2006) also clearly stipulates that the aluminium content of 1100 can reach 99.0%.
虽然大家都知道铝的密度是2.7,但是这是指的含铝量为99.9%的铝的密度。而在市场上常见的铝卷都是含有一定合金的,所以密度或大于2.7,或小于2.7。大家今天就普及一下常见铝板的密度。
Although we all know that the density of aluminium is 2.7, it refers to the density of 99.9% aluminium. The common aluminium coils on the market contain certain alloys, so the density is higher than 2.7, or less than 2.7.  Today we will popularize the density of common aluminum sheets.
首先说的是较接近铝密度的铝卷,该系列铝板称为纯铝板,密度为2.71.代表产品为1060,其它几种材质基本上也默认为密度为2.71.在该系列产品中铝含量都超过99%以上,其中还含有锰、硅等合金,所以密度稍微高于铝的密度。
First of all, the most close to the density of aluminium coil, this series of aluminium plate is called pure aluminium plate, the density is 2.71. Represents the product is 106 0, other materials are basically default density is 2.71. In this series of products, the content of aluminium is more than 99%, which also contains manganese, silicon and other alloys, so the density is slightly higher than the density of aluminium.
其次是2系,该系列代表产品是2024,铜合金含量高所以密度也比较大,在2.78.主要是因为该产品内部铜含量达到了3-4%之间,所以密度要高于普通纯铝。
The second is the second series. The representative product of this series is 2024. The density of the product is relatively high because of the high content of copper alloy, which is 2.78. The main reason is that the content of copper in the product reaches 3-4%, so the density is higher than that of ordinary pure aluminium.
3系的密度为2.73,主要是因为内部含有锰合金,5系铝板的密度比较轻,因为5系铝卷内部镁合金含量高,而镁合金的密度要低于铝的密度,通常5系铝板按照2.68密度来计算。6系铝板内部含有镁合金和硅合金,两种中和后密度基本上在2.7附近。
The density of the three series is 2.73, mainly because there are manganese alloys in the inner, but the density of the five series aluminium sheet is relatively light, because the content of magnesium alloy in the five series aluminium coil is high, and the density of magnesium alloy is lower than that of aluminium. Usually, the density of the five series aluminium sheet is calculated according to the density of 2.68. There are magnesium alloy and silicon alloy in the 6-series aluminium sheet. The density of the two kinds of neutralized aluminium sheets is about 2.7.

以上是几种常见铝卷的密度,结果并不像大家想象中的都是2.7,这主要也和合金含量有关,因为铝的密度是恒定的,但是内部合金含量的密度不同。在理论计算式要按照不同的密度来套取公式才能得到准确的重量,当然虽然相同系列的铝卷密度稍微有一点差距,但是差距不大
These are the densities of several common aluminium coils. The results are not 2.7 as you might imagine. This is mainly related to the alloy content, because the density of aluminium is constant, but the density of internal alloy content is different. In order to get the exact weight, the theoretical formulas should be set according to different densities. Of course, although the density of the same series of aluminium coils is slightly different, the difference is not big.
